Auto Backup & Export for Fusion 360 — User Guide

Platform: Windows and macOS. Every version is published as a Windows build and a separate macOS build with the same commands.

Auto Backup and Export keeps copies of the designs in your Autodesk cloud on storage you control. Each time you save, when you answer its daily or weekly reminder, or whenever you click Back Up Now (you choose), it copies the designs and files that changed to a folder you choose. Backups only read your cloud data: nothing in your Autodesk projects is ever changed, saved or deleted. When you need your designs back, Restore to Fusion uploads them into Fusion as new files, in this account or another one; see Restore to Fusion.

Quick start

1. Install the add-in from the Autodesk App Store and start Fusion. In Utilities > Add-Ins, Auto Backup and Export must be running with Run on Startup ticked: backups after each save and reminders happen only while the add-in runs. For a ZIP download, follow the installation guide. On macOS, the first start can show a security prompt; follow the add-in's notice and approve it in System Settings > Privacy & Security.
2. In the Design workspace, open the Utilities tab and find the Auto Backup panel: Back Up Now, Backup Settings, Backup Status, Restore to Fusion and About Auto Backup and Export.
3. Open Backup Settings while signed in to Fusion and online. The first time, a message says the license is being checked, then a notice confirms your free 3-day trial. Open Backup Settings again.
4. Under Backup folder, click Browse... to choose any folder, or pick a detected Google Drive, OneDrive or Dropbox folder under Cloud folders; the backups then go into a Fusion Backups folder inside it.
5. Under What to back up, tick the projects to back up under Projects. None is ticked at first, and nothing is backed up until you choose: tick every project to include new projects automatically, or set Back up from to Chosen folders to back up only some folders. Under When, choose in Back up what starts a backup: Each save (the default), Reminder (every day or every week the add-in asks whether to back up now) or Manual (only Back Up Now); see When backups run. Click Save.

That is all. With Each save, each design you save from now on is backed up. The designs you already have are not copied until you click Back Up Now once: it checks every selected project and backs up everything, in a progress window with a percentage and a Cancel button. With many designs this takes a while; see The first backup. With Reminder, click Back Up Now once for the first backup too; after that the add-in asks every day or every week whether to back up now. With Manual, backups run only when you click Back Up Now.

Backup Settings

What gets backed up

Like Fusion's own exports, these extra files contain the visible bodies; the .f3d and .f3z keep everything. If one of them fails, the .f3d or .f3z of that version is still kept, Backup Status shows the problem, and the file is tried again on a later check. A format your Fusion license does not allow (IGES and SAT with Fusion for Personal Use) is left out for all designs and named once under Problems; untick it under Also export.

When backups run

Under When in Backup Settings, Back up sets what starts a backup by itself. You choose one of three modes. Back Up Now works in all of them.

Backups are incremental: a file whose cloud version has not changed is not copied again. One design is handled at a time. Fusion is busy while each one is exported, so a large first backup is best started when you can leave Fusion for a while (see The first backup); Cancel in the Back Up Now progress window stops it after the current design. Fusion must be running and signed in. Backups wait while Fusion is offline and while a command is active, for example with an Extrude dialog open, and continue afterwards, so they never break into a command you are using. Nothing is backed up while Fusion is closed, and a design that was being backed up when Fusion closed is tried again later.

If the backup folder is not available, for example because its drive is unplugged or its sync app has stopped, backups wait and Backup Status shows Backup folder unavailable; they continue by themselves once the folder is back. A deleted backup folder is created again only when the folder that contains it still exists, so a missing drive is never re-created on another disk.

Reminders

A full check opens, exports and closes each changed design, which keeps Fusion busy for a few seconds per design. So with Reminder the add-in never starts one by itself: it asks Back up now? and you choose when.

• Yes starts Back Up Now, with its progress window and Cancel. No asks again two hours later, while Fusion is open.
• Counted from Save: the first reminder comes a day (or a week) after you click Save in Backup Settings with Reminder chosen, at that time of day; then every day (Every day), or on that weekday every week (Every week). For a first backup straight away, click Back Up Now.
• A backup covers it: a Back Up Now that finished after the reminder time, also one you started yourself, counts: no reminder comes until the next time.
• Saving again keeps the times. Saving Backup Settings again with the same Back up and Repeat does not move them. Changing Repeat, or choosing Reminder again after another mode, counts from that Save.
• Out of your way: the question comes only while Fusion is open and no command is running, once you have not started one for about a minute, and never during a backup or a restore. A reminder missed while Fusion was closed comes once when Fusion is next open.
• Next time: the note under Repeat in Backup Settings and the Mode line in Backup Status show when the next reminder comes.

Back Up Now

Click Back Up Now to check every selected project and back up whatever changed, straight away, in any mode. It starts at once, without a dialog to confirm, and does not wait for idle time; it only waits while a command is active. A progress window shows how far it is:

1. First the add-in lists the folders of every selected project, so it knows how many files need a backup. The window shows, for example, Checking cloud folders: 12 of 30 (40%) with the number of files found so far; folders found inside others join the count as they turn up.
2. Then it backs up those files one at a time. The window shows, for example, Backing up file 4 of 25 (12% done) and the name of the design; the bar moves on each time a file is finished. A big assembly can take a minute or more, and Fusion cannot report progress inside one file, so the bar waits on it.
3. At the end it waits for any .f3z archives or downloads that Fusion's cloud is still delivering. Then the window closes and a message shows the counts: Backed up, Problems, Waiting (see Designs that wait) and Cloud files checked. It also names the assemblies that are open in Fusion: they are backed up as .f3z once you close them.

Back Up Now does not wait for idle time, so Fusion is busy most of the time while it runs: each design keeps it busy for a few seconds (longer for large designs), and the progress window and its Cancel button respond only between designs. If you start a command meanwhile, Back Up Now pauses until you finish or cancel it, and the window says so. Click Cancel in the progress window when you need Fusion back:

• Back Up Now stops after the design it is backing up at that moment (while it lists the cloud folders, almost at once). No result message is shown.
• Everything already backed up is kept, and .f3z archives that Fusion's cloud is already building still arrive.
• Click Back Up Now again later: it checks again, skips everything that is already backed up, and carries on with the rest.
• Cancel stops only this Back Up Now. With Each save, the designs you save are still backed up. With Reminder, a backup that is due is asked about again two hours after its reminder. To stop backups for a while, choose Manual.

If only Fusion's empty Untitled design is open, Fusion closes it by itself as soon as a backup opens a design; the add-in opens a new empty Untitled design again when it is done. Your saved and changed designs are never closed.

If Fusion goes offline or the backup folder is not available, the window says so and Back Up Now waits; click Cancel if you do not want to wait. Clicking Back Up Now while a check without a window is running (after Retry problems now) turns it into Back Up Now, with the progress window. If no backup folder, or no project (or folder) to back up, has been chosen yet, Back Up Now asks you to open Backup Settings first. While Restore to Fusion is running, Back Up Now does not start and says so.

Backing up chosen folders

With Back up from set to Chosen folders, only those folders are backed up, each with all its sub folders: Back Up Now checks only them, and with Each save a design you save elsewhere is not backed up. The backups land in the same place as with whole projects (<hub>/<project>/<folders>), so switching between the two copies nothing twice.

• A chosen folder is remembered by its cloud ID: renamed or moved, it is still backed up, under its new name and place. Backup Settings and Backup Status show the new name after the next full check.
• A chosen folder that was deleted and made again in the same place (for example by Restore to Fusion, where it was, made again) is a new folder for Fusion: it is found at its place and backed up like the old one.
• A folder inside another chosen folder is checked once.
• A chosen folder that is gone is named in the Back Up Now message and under Problems in Backup Status, and marked (not found) in Backup Settings: untick it, or add it again.
• Backup Status shows what is backed up next to Backing up.

After you change the settings

A new backup folder, more projects ticked, other folders chosen, more formats under Also export, or Copy uploaded files newly switched on need a full check to fill them in: click Back Up Now. A Back Up Now that is running when you click Save fills them in too. With Reminder, the reminders keep their times.

Designs that wait

A design that cannot be backed up at the moment is not skipped: it waits and is backed up by itself once the reason is gone. Backup Status lists each waiting design with its reason under Waiting.

Waiting designs are remembered only while Fusion runs. If Fusion is closed first, the next full check backs them up: your next Back Up Now (with Each save, also the next save of that design).

The first backup

The first backup of a large account takes time. Each design that is not open is downloaded, opened hidden, exported and closed, which keeps Fusion busy for a few seconds per design (longer for large designs and with each extra format). With Each save or Manual, start it with Back Up Now when you can leave Fusion for a while, for example before a break; if you need Fusion back, click Cancel and run it again later. With Reminder, answer No until such a moment. You can also tick a few projects first and add the rest later. After that, only changes are backed up.

Stopping backups for a while

Choose Manual in Back up and click Save. Nothing then runs by itself and no reminder comes: designs you save are not backed up, and designs that were waiting are left for your next Back Up Now. .f3z archives that Fusion's cloud is already building still arrive. Back Up Now still works, and a Back Up Now that is running goes on until it is done or you click Cancel, together with the designs waiting at that moment.

To start again, choose Each save or Reminder, and click Back Up Now once for the designs saved in the meantime.

Where files go

Backups mirror your cloud: hub, project, then the project's folders.

<backup folder>/
  Acme Hub/                                  hub
    Fixtures/                                project
      Clamps/                                cloud folder
        Clamp v12 2026-10-06 183005.f3d
        Clamp v12 2026-10-06 183005.step
        Clamp v11 2026-10-02 091542.f3d
        Frame assembly v4 2026-10-05 091218.f3z
        Datasheet v1 2026-09-30 140527.pdf
  .autobackup/
    manifest.json

• File names hold the cloud name, the version number, and the local date and time of that version, to the second. The date and time also tell apart saves that keep the same version number.
• Same names: when two files in one cloud folder have the same name (letter case ignored), each gets a short tag from its cloud ID, for example Bracket [3fa2c1] v3 2026-10-01 101244.f3d, so they never overwrite each other.
• Safe names: characters that Windows or macOS do not allow in file names become _, and long folder and file names are shortened so the full path stays under 240 characters.
• Manifest: .autobackup/manifest.json in the backup folder records every backup: the cloud file, its version and the files written. It is how the add-in knows what is already backed up and which files it wrote, and where Restore to Fusion finds the original folder and file names, so keep it with the backups. A new backup folder starts its own history, and the old folder is left as it is. How the new one is filled: see After you change the settings.
• Backups kept: for each cloud file the newest 5 backups are kept (Backups kept per file, 0 keeps all). Older backup files written by the add-in are deleted. Nothing else ever is: files you add yourself, and anything outside the backup folder, are never touched.
• Missing files: if a backup file of the current version is missing, the next run writes it again. A backup file you rename or move is no longer managed by the add-in, so it is never deleted.
• Sync folders: each file is exported and checked on this computer first, then written under a temporary name and renamed when it is complete, so a sync app never uploads a half-written backup.

Restore to Fusion

Restore to Fusion puts backed-up designs back into Fusion: into a new project (the default) or one you already have, in this Autodesk account or in another one you sign in to. It uploads the newest backup of each file and, with the backup history, recreates the original folders and file names. Use it when designs were lost or deleted in the cloud, or to move your designs to another account. Single files can also be uploaded by hand; see Restore by hand.

How to restore

1. To restore into another Autodesk account, first sign in to Fusion with that account. Then open Restore to Fusion in the Auto Backup panel.
2. Under From the backup, Backup folder shows the folder from Backup Settings. To use another one, for example a copy of your backups on another drive or computer, click Browse.... A folder inside a backup folder works too: choosing a project's folder there chooses that project.
3. Project lists the projects found there, each with its number of files and its hub. A project renamed in Fusion is listed once, under its newest name. The line below it says whether the backup history was found; see What comes back.
4. Folder is Whole project, or one of the project's folders: then only that folder comes back, with all its sub folders. A folder chosen with Browse... inside the backup is chosen here too. See Restoring one folder.
5. Under Into Fusion, choose the Hub (the active hub is chosen first), then the Project: New project (the default for a whole project) or one of the hub's projects. For a new project, New project name holds its name: the backed-up project's name followed by (restored), which you can change. Into folder says where in that project the files go: Project root, the folder's own path, or a folder chosen with Choose folder... (Fusion's own folder picker, where you can also make a new folder). The line below it says what happens. Before you choose an existing project, read What a restore does not do.
6. Under Options, all on by default:
   • Skip .f3z parts: see Assemblies.
   • Uploaded files: your non-Fusion files go back as well.
   • STEP fallback: a design whose .f3d and .f3z backups are all gone comes back from its newest STEP file, as plain geometry without the timeline.
7. Click Restore. A progress window opens. The add-in first reads the backup (a large backup in a cloud-synced folder can take a moment), then the window shows the file being uploaded, how many files of how many, and the percentage. Two files are uploaded at a time.
8. At the end, a message shows how many files were uploaded, how many parts were left out because their assembly brings them, how the parts of assemblies were put in place, any problems with their reasons (the log lists them all), and the project's name. Open that project in the Data Panel to see the files.

Click Cancel in the progress window to stop: the window closes at once and no more files are uploaded. Files that Fusion is already uploading (at most two) still arrive, and the message then shows what was uploaded. Cancel before the first upload creates nothing, not even the new project.

• The progress window does not lock Fusion: you can keep working while the files go up. The restore waits while Fusion is offline or a command is open (the window says so), and goes on afterwards.
• While it runs, backups wait and Back Up Now does not start; Backup Status shows how far the restore is. Restore to Fusion does not start while Back Up Now is running either: it says so and offers only Close. In Each save mode, the files the restore uploads are not taken for your saves; designs you save elsewhere meanwhile are backed up once the restore has finished.
• A file that Fusion cannot upload is tried once more after the others; only then is it listed as a problem. After three failed uploads in a row (the network may be down), the restore waits a minute before it goes on.
• An upload that Fusion has not finished after 30 minutes is listed as a problem: check that file in the project before you upload it again.
• If Fusion is closed during a restore, the restore stops and does not resume. Restore again into a new project, or upload the missing files by hand.

Restoring one folder

Choose the folder under From the backup > Folder. Its files and sub folders come back; the folders above it do not.

• Back where it was: when the backed-up project is in the Autodesk account you are signed in to (in any of its hubs), that project is chosen, with Into folder on the folder's own path. If the folder is still there, the files are added to it (where it was): nothing in it is replaced, so a design that is still there will be there twice. For a separate copy, click Choose folder... and make a new folder. If the folder was deleted, it is made again in the same place (where it was, made again).
• The old folder is looked for by its name and place: one renamed or moved in Fusion since is not found there. Pick it with Choose folder....
• Somewhere else: any of this can be changed. Choose another project (the same path is made there, or choose Project root), a New project, or click Choose folder... and pick any folder; the folder's files and sub folders then go straight into it. A whole project picked there means its root folder.
• In another account, or when the project is gone, the folder goes into a new project under its own path, unless you choose otherwise.
• Back on Whole project, the project the dialog had chosen for the folder is given back (a new project, unless you had chosen one); a project you chose yourself stays.

What comes back

• The newest backup of each file that is still on disk: the .f3d or .f3z of each design, and your uploaded files. Older versions stay in the backup folder; to bring one back, upload it by hand.
• With the backup history, the .autobackup/manifest.json of the backup folder (also found when you choose a folder inside it): the original folder and file names, including names that were shortened in the backup folder. A name with characters that a file name cannot hold, such as : or ?, is uploaded with _ instead and then renamed in Fusion to its original name. The names are those Fusion showed at the last backup or full check, so a design or folder renamed in Fusion comes back under its new name.
• Without a history, for example a project folder copied on its own, names come from the files: the folder you choose becomes the project, the folders below it become its folders, and the version, date and time are taken off each name, so Clamp v12 2026-10-06 183005.f3d comes back as Clamp. Of several backups of one design, the newest is used. Only files named like this add-in's backups are uploaded; any other file in the folder is left alone. Choose the project's own folder, such as Acme Hub/Fixtures in the backup folder; otherwise the hub and project folders become folders in Fusion as well. A whole drive cannot be chosen.
• Folders: files go into the same folders as in the backup. In an existing project, a folder that is already there with the same name is used.

Assemblies (.f3z)

An assembly backed up as .f3z comes back with its linked parts. Fusion first unpacks it into the assembly and a new copy of every design it links to, all in the assembly's folder. When the uploads are done, the restore puts each part in its own folder, as in the backup, and makes the restored assembly use the newest backup of each part: where a part's own backup went up as well, the assembly is saved as a new version that uses it (described as Restored by Auto Backup and Export). The extra copy that came with the .f3z stays next to the assembly: the assembly's first version still uses it, so Fusion does not let it be deleted, and the message lists it. Each part is then in its own folder, and the restored assembly uses it, not the original design. The progress window says when this is going on; Fusion can take a few minutes to unpack a large assembly.

• With Skip .f3z parts on (the default), a part's own backup is not uploaded when the assembly's .f3z holds the same or a newer version of it: the copy from the .f3z goes to the part's folder. The message counts these parts as left out.
• A part whose own backup is newer than the copy inside the assembly's .f3z (it was changed after the assembly was last saved) is uploaded as well, and the assembly uses it, so newer work is never lost. If an assembly cannot be uploaded, the parts left out for it are uploaded on their own instead.
• Turn it off to upload every part's own backup too: the restored assemblies then use those.
• A part used by several assemblies comes back once, as the newest copy any of them holds, and they all use it.
• A part whose own backup is not part of the restore (one that an assembly links from another project, or from outside the folder you restore) stays next to its assembly, and so does a part whose name another design in the same .f3z also has. Under Left in place, the message lists such parts of an assembly whose other parts were put in place, and anything that could not be done, such as an extra copy that Fusion did not delete.
• With the backup history, parts are matched by their cloud ID. Without a history, a part is matched by its name, and only when one design of that name is in the backup; two designs that share a name both come back.
• An assembly that was backed up as .f3d (with Assemblies as .f3z off, or when no .f3z could be made) still links to the parts in your cloud: in another account, or once those parts are deleted, its links are missing.

What a restore does not do

• No version history: each file is uploaded as a new design at version 1. The cloud version history, comments and share links are not part of a backup. Drawings, Electronics files and configured designs are not backed up in this version, so they cannot be restored either.
• Nothing that was in Fusion before is changed: a restore adds files, and the project and folders they need. It changes only files it has just uploaded itself: it renames one to give it its original name, and puts the parts of a restored assembly in place (see Assemblies). Restoring into an existing project adds the files next to the ones already there, even when the names are the same: you then have two files of that name, never a new version of the existing one.
• Restoring twice gives two copies: restoring the same project again uploads every file again. To redo a restore that stopped half-way, restore into a new project, or upload the missing files by hand.
• Nothing else is deleted, in Fusion or in your backup folder: a restore only tries to delete the extra part copies that its own .f3z uploads made, once no design uses them (Fusion usually keeps them, see Assemblies). The backup files are only read.

Like Back Up Now, Restore to Fusion needs the trial or a subscription of the Autodesk account that is signed in; see License and trial. Restored files are new files in the cloud: with every project ticked under Projects in Backup Settings, your next Back Up Now backs them up as well; with Chosen folders, those in a chosen folder are (a chosen folder the restore made again is followed).

Restore by hand

Any backup file can also be uploaded by hand, for example an older version of a design:

1. In Fusion, open the Data Panel, go to the project and folder where the design should go, and click Upload.
2. Select the .f3d or .f3z backup and upload it. Fusion processes it in the cloud and the design appears in that folder.

• Fusion names the design after the file, so it is called, for example, Clamp v12 2026-10-06 183005. Rename it in Fusion afterwards, or upload a renamed copy such as Clamp.f3d (rename a copy, not the backup file itself).
• An .f3z recreates the assembly with its linked parts as new, independent copies in that folder. The restored assembly refers to these copies, not to the original designs.
• You can also open an .f3d with File > Open > Open from my computer and save it to a project.
• STEP files open in Fusion and most other CAD systems as plain geometry, without the Fusion timeline.
• Uploaded files (PDF, ZIP, images) are plain copies: use them directly or upload them again.

Status and log

Backup Status works without a license, so you can always check and reach your backups (only Restore version needs one):

• Status: what the add-in is doing (for example Waiting for an idle minute or Backup folder unavailable), the Mode, the backup folder, the last full check, the progress of a running backup or restore, and any .f3z archives still being built by Fusion's cloud. Mode is the Back up choice; for Reminder it also shows when the next reminder comes (now: once you have not started a command for about a minute).
• Problems: designs that could not be backed up, with the reason; chosen folders the last full check did not find, and cloud folders it could not read.
• Waiting: designs that are backed up later, each with the reason and what it waits for; see Designs that wait.
• Recent: the backups, restores and problems of this Fusion session.
• Open backup folder, Open log and Retry problems now. Retry problems now clears the problem marks and runs a full check like Back Up Now, but without the progress window: it starts when you close Backup Status, and a message shows the result.
• History: each backup of each design in a backup folder, and Restore version; see Backup history.

When a design fails three times on the same version, it is marked skipped until it changes: backups, including Back Up Now, leave it alone until a new version is saved, or until you click Retry problems now.

The activity log is a plain-text file, logs/autobackup.log, in the add-in's data folder (see Local data). It rotates at about 1 MB and keeps the three previous files. It contains the names of your designs and folders; attach it when you report a problem.

Backup history

The History part of Backup Status shows what a backup folder holds. Choose a Project and a Design (each with the number of backups kept); Version lists each backup of it still on disk, newest first, with its version number, when that version was saved in Fusion and its files (.f3d or .f3z, STEP). The line below adds their sizes and when the backup was made. How many versions are kept per design is set by Backups kept per file in Backup Settings.

• Any backup folder: Backup folder starts with the one in Backup Settings; Browse... opens another, for example a backup folder copied from another computer. Its history (the .autobackup folder inside it) goes with it, so the same designs and versions are shown. A copy of backup files without that history works too: the versions come from the file names.
• Restore version (the button at the bottom) uploads the chosen version as a new design named after its version, for example Bracket (v12): Fusion cannot make an older version the newest one of the existing design, and nothing in Fusion is replaced. A version whose Fusion file is gone comes back from its STEP file (geometry only). An assembly (.f3z) brings its linked parts along, as new copies.
• Restore into: where it was, in its own project and folder (the folder is made again when it is gone), or a folder chosen with Choose folder.... When its project is not in this Autodesk account (a backup from another account, or a copy without its history), choose a folder first.
• It runs like Restore to Fusion, with its progress window and a message at the end, and needs the trial or a subscription.

Nothing is backed up?

• Backup Settings has a saved backup folder, and the folder or drive is available (otherwise Backup Status shows Backup folder unavailable).
• Projects are ticked under Projects in Backup Settings, or folders chosen with Chosen folders. None is ticked after a new install; Backup Status then shows Backing up: no project chosen yet.
• Back up fits what you expect. In Manual, only Back Up Now backs up. In Each save, only the designs you save are backed up by themselves; designs you had before, and changes saved by others or on another computer, need Back Up Now. In Reminder, nothing is backed up until you answer Yes or click Back Up Now; the Mode line in Backup Status shows when the next reminder comes.
• Fusion is signed in and online, and no command dialog is open.
• The design is not listed under Waiting in Backup Status. If it is, the reason says what it waits for.
• The trial or a subscription is active: check About Auto Backup and Export.
• The add-in runs: Utilities > Add-Ins shows it running, with Run on Startup ticked.
• The file is in a ticked project (or in a chosen folder, with Chosen folders) and is not a drawing, an Electronics file or a configured design.

Fusion for Personal Use

With a Fusion for Personal Use license, .f3d backups and the STEP, SMT, STL and 3MF extra files work; Fusion does not allow IGES and SAT. If Fusion refuses an export for your license type, Backup Status shows the reason.

License and trial

• Free trial: 3 days. It starts on VanThanBK's license server the first time you click Back Up Now, or open Backup Settings or Restore to Fusion, while signed in and online. Starting Fusion, or opening Backup Status or About, does not start it.
• Subscription: US$7 per month or US$39 per year, per user, from the Autodesk App Store. The add-in confirms the subscription of the signed-in Autodesk account through Autodesk; a subscription from the Windows or the macOS listing unlocks both platforms.
• Backups run only while the trial or a subscription is active. Without one, Back Up Now, Backup Settings and Restore to Fusion show a license message and close, and backups after a save and reminders stop. Backup Status and About keep working, and your backup files stay where they are; you can still upload them by hand (see Restore by hand).
• About Auto Backup and Export shows the license status, the Autodesk account and the App ID. Use Check license now after buying. If you received an activation code, enter it in Activation code and click Apply. About also opens the product page, this guide and the privacy policy.
• Offline: after a successful online check, the license is remembered for up to 7 days in a signed cache for this product and Autodesk account. Backups themselves need Fusion online.
• Updates: About shows when a newer version is published, and Download latest version opens it in your browser for licensed users. Before installing it, select the add-in in Utilities > Add-Ins, clear Run on Startup and click Stop. Close Fusion, replace the add-in folder, restart Fusion, then run the new version with Run on Startup ticked. See the update guide.

License and update checks run in the background, never on Fusion's modeling thread. The unlocked Autodesk review build performs no identity, cache or licensing network access.

Local data, privacy, and support

Backups are written only to the folder you choose. If that folder is synced by Google Drive, OneDrive, Dropbox or another service, that provider's own app uploads the files under your account. The add-in never signs in to any cloud storage, and your designs are never sent to VanThanBK. Restore to Fusion uploads backups only to the Autodesk account that is signed in to Fusion, through Fusion's own upload.

License checks send your Autodesk user ID, email and the App ID. Update checks send only the App ID and platform. A download request sends your account details, and the download is recorded. Updating or uninstalling the add-in leaves your backups, settings, log and license cache in place; delete them yourself if you no longer need them.

Current limitations

• Fusion must be running, signed in and online. Nothing is backed up while Fusion is closed; a reminder missed meanwhile comes once when Fusion is next open.
• The first backup takes time and keeps Fusion busy for a few seconds per design; see The first backup.
• .f3z archives depend on Fusion's cloud export and take about 20–40 seconds per assembly, longer for large ones. If the cloud does not deliver an archive, that backup is tried again on a later run.
• An assembly that is open in Fusion is backed up as .f3z once you close it, not while it is open; the add-in reminds you with a message. A design that Fusion has loaded only as a linked part of an open assembly waits until that assembly is closed. See Designs that wait.
• Drawings (.f2d) and Electronics files are not backed up in this version, and configured designs are skipped.
• Each backup holds one version. Cloud version history, comments and share links are not included, and Restore to Fusion uploads each file as a new design at version 1; it never adds a version to a design already in Fusion.

Development roadmap

These items are planned. They are not available-feature claims or release-date commitments.

• Drawings to PDF: back up Fusion drawings as PDF files next to their designs.
• Direct Google Drive upload: send backups to Google Drive without the Drive for desktop app.
