All other LXC backups are working just fine but this one gives:

Which template did you use to setup the container? What filesystem is in use as / in the container? I cannot reproduce this here, neither with zfs with turned off posixacls, nor with lvm-thin/ext4 nor with local/ext4 with acl=0.
 
That LXC container is: Operating system Linux 4.2.8-1-pve (Ubuntu 14.04)

mount shows:
/dev/loop4 on / type ext4 (rw,relatime,noacl,data=ordered)

After the basic installation I installed Streisand into it => https://github.com/jlund/streisand
That is all that was done to that container as far as I remember.

Thanks for looking into it.
 
Like I said, I have the exact same combination of file systems here (ext4 with noacl and your complete config in the container, ext3 with the same mount flags for backup) and it works as expected. The problem seems to be that rsync thinks that your container file system does not support xattrs. You can try turning acls on for the container's rootfs (and rebooting it for the setting to take effect), but it should work either way..
 
Hello guys, I have the same problem :

Code: 
    support.econcept.local    FAILED    00:07:33    command 'rsync --stats --numeric-ids -aH --delete --no-whole-file --sparse --one-file-system --relative '--exclude=/tmp/?*' '--exclude=/var/tmp/?*' '--exclude=/var/run/?*.pid' /proc/3039/root///./ /mnt/pve/PVE_Backup/dump/vzdump-lxc-103-2017_08_28-20_19_09.tmp' failed: exit code 23

How can I enable acls ? I have many LXC container wich backup without error, but this one failed every backup !
 
this thread is about vzdump tar backups, not PBS - please open a new thread and clearly describe your issue:
- versions of PVE and PBS
- config of containers that fail to backup
- storage.cfg
- full backup task log
