I have excluded the paths correctly, but still fails

You have excluded the only folder that would have been backed up, so of course there's nothing left. If you don't want to backup that container set Skip to Yes.

@Kilrah
I don't want to backup anything from the filesystem, but I still want to make use of the auto-update feature the tool offers. That is why I don't set it to "Skip".

If you notice, the error message actually says that there is a tar problem when checking for a folder that shouldnt even be checked for, the "/logs" folder.
This problem only appears to happen with this particular container (clamav) though. I have another container configured the same way (no need to backup anything, just stop, update and bring back online) and I've excluded all folders related to the container and backup works ok 😓

I have a container that has always failed to backup and I finally tracked down the root of the problem, it's with the tar command itself but I have a workaround that the plugin's cleanup logic is preventing when saving.

The config for that container

I have Save external volumes? set to yes because I want one of the external volumes backed up, but that means I need to exclude /mnt/user obviously.

I figured out the problem with tar is the --exclude '/mnt/user' by taking the Generated tar command from the logs and by adding a trailing / it works. I have a feeling it's because of the /mnt/user0 folder, which I'm not sure why that exists but I'm still troubleshooting that. The problem is if I change the line in the UI to /mnt/user/ when I save it goes back to `/mnt/user`

For now I've disabled Save external volumes? and have a separate script handling the one external volume, but I don't like that solution long term

Are you aware of the auto update plugin?

I am aware, great tool. Although I don't want to have to mantain 2 apps when one could do the trick 💻

Then click "show advanced options" and set it to ignore errors.

Hi,
I have a problem updating the Immich container.
As you can see in the logs, the container is stopped and the update process runs. Packaging the folders also completes without any issues.
However, when it performs the verification afterward, it reports an error even though the container was stopped.

Does anyone maybe have an idea what could be causing this?

A file changed while the backup ran. Immich usually doesn't run alone so make sure to put it into a group along with all its companion containers. / anything else that might touch the folder.

How do you assemble this?

Use the group feature in the plugin, click on them in AB settings

Sorry, but I can’t find this function. Could you maybe send me a screenshot of it?

I found the function responsible for formatting. It’s somehow shifted.

Hi,

I found a line break in the HTML file that's changing the formatting of the container backup settings.

Hello, although I now did this in groups and everything related to Redis was stopped at the same time, this error unfortunately still occurs.

I found a line break in the HTML file that's changing the formatting of the container backup settings.

Please try latest version 2026.03.13.

I recently updated from Unraid 6.12.10 to 7.2.3. After the update, I had to change the Appdata Backup version to a newly maintained version, and I noticed that Appdata Backup is no longer automatically running on my schedule. It's set to run Weekly, Friday, 4am. There are no logs at the time it's supposed to run, it just doesn't run. Anyone else run into an issue like this? I'm running the latest version of Appdata Backup. The plugin works fine if I initiate a Manual Backup, it's just that it's not automatically running on the schedule anymore. Any ideas?

Edited March 13Mar 13 by ccwod

So you did the config import then? Did you saved the settings one more time (even with no change)?

Hello,

I am experiencing an issue with the Appdata Backup/Restore plugin where the settings page only shows a blank white screen.

Environment

• Unraid version: 7.2.4

• Plugin: Appdata Backup/Restore

Problem

When opening the plugin page via:

Settings → Appdata Backup / Restore

the page loads but remains completely blank (white screen).

Accessing the page directly also results in the same behavior:

/Settings/AB.Main

Additional behavior

After opening the plugin page, the Unraid WebGUI becomes unstable.
Sometimes the GUI stops responding and I cannot access it anymore until I restart the web services.

I need to restart the GUI with:

/etc/rc.d/rc.nginx restart
/etc/rc.d/rc.php-fpm restart

After restarting nginx the WebGUI becomes accessible again.

What I already tried

• Reinstalling the plugin through Community Applications

• Removing the plugin and reinstalling it

• Restarting nginx and php-fpm

• Clearing the browser cache

• Testing with hostname and direct IP

• Rebooting the server

Result

The plugin appears to install correctly and the files exist under:

/usr/local/emhttp/plugins/appdata.backup

However, opening the plugin page still results in a blank page with no content.

Additional checks

The server has normal network connectivity and other plugins load correctly.

Question

Has anyone seen this behavior before or knows what might cause the Appdata Backup plugin page to render completely blank?

Any help or suggestions would be appreciated.

Thank you.

Go to Tools -> PHP and enable error reporting and/or display errors (not sure how the wording is). Then try again

Also: Open the log Terminal, open the page and check it for upcoming messages.

I think the problem occurs when the SMB share from my backup NAS is not responding. In that case, I am unable to open the AppData Backup settings.

Does anyone have an idea how I could fix this?

Edited March 16Mar 16 by Toby-ch

Yea, its clearly mentions unassigned Devices.

Nothing to do with this plugin. And also no idea why its coming up on the plugins settings page :(

When opening AB settings it probes the backup destination for some reason (spins my destination disks up if they were spun down) so if the destination is on an unavailable remote it's not surprising it hangs.

Interesting. The settings page is probing nothing. But I include the DockerClient class from Unraid and this includes several other helpers. Maybe one of this causes that issue. However, not a plugin fault. It only triggers this issue.

While looking through my Appdata Backup files, I found that xml files for dockers that I have long since uninstalled are still being backed up.

There are no folders in my Appdata for said dockers, so I am wondering where these residuals are coming from.

Can anyone shed a light on this? There is no sign of residuals when running Cleanup Appdata or Fix Common Errors

Thanks in advance!

EDIT: Found it! Turns out that templates (XML files) are still stored in /boot/config/plugins/dockerMan/templates-user/

As of this past month, my backups seem to be failing. No issues prior to now. Debug Log saying "No space left on device" but my array has about 500GB free, so I'm not sure where that's coming from. Any insight is appreciated!

The backup is .
