Hello,

Today, I noticed that my backup folder is empty. Actually an automatic backup should be stored here every 7 days, which also worked once.
So I tried to create a manual backup (Including Data, without compression).
it failed with the following output:

[ nc-backup ] (Wed Oct 4 13:32:09 CEST 2023)

Does anyone see a solution?
Are there other ways to perform a backup?

maybe useful information:
The “nextcloud check” in the Systeminfo says “error”

I checked the file that is supposed to keep the function isn’t present at my site (/var/www/nextcloud/apps/groupfolders/lib/Versions/VersionsBackend.php). It seems as if you’ve installed a app that deals with groupfolders. I’d even deactivate and/or reinstall this app before running a backup.

For my backups (including nextcloud data and database) I use this tool :
https://www.borgbackup.org/
it’s foss, it’s reliable, it’s effecient, it’s complete, and extremely well documented.
I tested it recently after a full server migration.

Thanks for the hint regarding the “groupfolders” app.
In fact, there was a pending update for this app and after installation, the update process worked again.

Also i will have a deeper look at borgbackup :slight_smile:
