Auto backup doesn't delete files

[ottobaer]

Hi,

I've got auto-backup and removal after 3 days enabled, but the cronjob doen't delete the old backups. It creates them just fine and I have the entry in the /etc/cron.d/

steam@b10e80ecd557:/etc/cron.d$ cat auto-backup
*/45 * * * * AUTO_BACKUP_REMOVE_OLD=1 AUTO_BACKUP_DAYS_TO_LIVE=3 /usr/sbin/gosu steam /bin/bash /home/steam/scripts/auto_backup.sh >> /home/steam/valheim/logs/auto-backup.out 2>&1

I tried running the script manually from the scripts directory and it creates a backup but won't delete them.
The owner is the user steam (id 1000) which corresponds to a user on the system, not named steam - is that the problem?

steam@b10e80ecd557:~/backups$ id
uid=1000(steam) gid=1000(steam) groups=1000(steam)

root@server /opt/valheim-mods # id 1000
uid=1000(chb) gid=1000(chb) groups=1000(chb)

Here is my docker-compose.yml

Are you on a recent pull of latest ?

Confirmed this works.

Same issue. My backups are not deleted. I set it up to "1 day to live". However backups from more than 1 days are still there and I'm forced to delete it manually from container's host.

@Moulagofre are they by chance storing the past 48 hours of backups?

[TheDakk]

@Moulagofre read through some of the previous comments, it stores 1 more day than what you configure.

@mbround18 @TheDakk Last time I think there was backups from 3 days ago and that's why I posted a comment. But maybe I'm mistaken and I wonder if, actually, my disk is too small and I can't pass the 48 hours threshold until deletion occurs (because my disk might be full before).
Now I've changed my config to 1 backup every 30 minutes (from 1 every 15). I'll keep you updated guys.
