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 .

Solved in the Unraid Discord! Thanks. Explanation below in case anyone comes across this looking for the solution:

Check min free space setting on your backups share.

I was surprised to discover, after upgraded to 7.3 and internal boot, "flash backup" still works. No reconfiguration necessary. Thank you!

hi guys, i recently discovered that as of december 2025 my plugin never run again.
there are no files in /tmp/appdata.backup
just run a manual backup and it ran fine so its probably my custom cron that is silently failing:
0 10 * * 4#3

it was suppose to run every 3rd (#3 )Thursday (day 4) of the month at 10:00AM. Its probably the hash that is breaking this. Do I need a different format for unraid?

https://crontab.guru/ says it's invalid too.

yes I saw that too.
wanted to try this next but its not allowed:
0 10 22-28 * * [[ $(date +%u) -eq 4 ]]

input field seems to be limited by nr of characters.
Thought I'll just do it once every 4 weeks then but even that seems impossibe in cron.

update: I looked at the cron line created when scheduling inside the plugin, I now set it up running as a user script using:
0 10 22-28 * * [[ $(date +%u) -eq 4 ]]
I switched to 4th Thursday as the 3rd aleady passed :). Fingers crossed

I mean to me what would be "really bad" is to only backup appdata once a month 😁 for me it's nightly

Hi

I’m trying to exclude the relevant Plex folders from the appdata backup, but the backup is still taking a long time and growing very large. I’ve added entries to the “Global exclusion list” (see below), yet it still spends ages on Plex and the file size keeps increasing. I suspect the path is incorrect, but I’m not sure how to identify the correct one. Can anyone advise?

mnt/User/appdata/binhex-plex/Plex Media Server/Cache

mnt/User/appdata/binhex-plex/Plex Media Server/Media

Do any of your paths loop into one another? I had a file in my Plex Library and loading that file into the paths to hold media files will cause a loop that is purpetual and will fill your log file in minutes.

This fixed it! Thank you!

So I got the plugin setup with order for the containers to be started after backup but it does not seem to work as my VPN container should start first and then the others but timing is off as the others that depend on it start up either before or same time.

Did you group the containers that should be together and set order for that group?

How do you group them? i see no settings for groups in the appdata backup settings.

Only see startup order.

Expand container settings, enter a group name, apply, then select the group on any other container that needs to be part of it, then you have a separate block on the right to order them.

I have a container which I recently transitioned to being managed/run via docker compose (specifically, a dockhand client running on another host) rather than the Unraid Community Apps template.

Whenever the container is stopped/started, for example for app data backup, or for auto update applications (side note: forgot I had this and turned off for all docker containers) it restarts an older version of the container: namely a different container build, not routing the container through gluetun, etc.

I deleted the template in /boot/config/plugins/dockerMan/templates-user/ and I am hoping this fixes it. I had already disabled the container from being backed up but maybe because gluetun was backed up via app data backup, it still stopped and started the container in question. Basically I want to make sure if Unraid/the plugin ever stops this container, the newer version managed by compose (with all its variables, network, etc) is setup. Any advice?

TLDR: Migrated qBittorrent from Unraid Community Apps to Docker Compose (managed by Dockhand on a separate host). Unraid's Appdata Backup plugin keeps restarting the old version of the container.

It can't start something that isn't there, so that suggests you didn't remove the old container before moving to compose

Believe I did. Also I believe if you try and start a docker compose stack where the container name is the same as a created but stopped container, it will give an error.

My plugin has been working for a couple of years, but recently it's not been working right. I haven't made any changes to any of the settings. I don't know if something changed with an update, or if something happened with my dockers, but the last few backups the plugin has made ended up with lots of errors about the dockers not restarting. I came home from work today and had another dozen emails about the dockers not starting. HOWEVER, when I checked, all the dockers were started fine. Checking the logs and the debug logs, it appears they're starting, just not as fast as the plugin would like.

Is there a way to set a longer delay before it gives up and throws an error?

Update logs

I would like to request a 'feature' request, more of a settings tweak request. That you can limit the error messages being sent to just 1 per backup. If I have new containers added that don't have a volume, I am getting 'error' messages for each one, so for example, recently I installed Nextcloud AIO, with its internal multiple container system. Today's backup, I got 6 notification messages sent to my phone.

Although I think they should probably be 'warnings' instead of errors, my request is that you only get 1 error notification message per backup, to reduce the spam. Thanks for the plugin.

I have changed the scheduling in the WebGUI to daily 1 pm. An overview of all cron jobs with "crontab -l" shows that this change has no effect.

But backup is still running at 2 am, 14 pm, and 18 pm.

How can I make the changes I made in WebuGUI take effect?
