Hi together,

I have 8 containers running with a daily backup pbs. Now I try to restore all containers to a new pve host. 7 containers working fine, regardless if there are privileged or unprivileged.

Now I try the last one to disks (root 10, mp0 650GB). I getting the following error after round about 80-100GB of the recovery process:

recovering backed-up configuration from 'pbs1:backup/ct/103/2021-03-25T01:05:35Z' restoring 'pbs1:backup/ct/103/2021-03-25T01:05:35Z' now.. Error: error extracting archive - error at entry "": failed to apply directory metadata: failed to apply acls: Error while restoring ACL - ACL invalid TASK ERROR: unable to restore CT 103 - command '/usr/bin/proxmox-backup-client restore '--crypt-mode=none' ct/103/2021-03-25T01:05:35Z root.pxar /var/lib/lxc/103/rootfs --allow-existing-dirs --repository sa-bckpve2@pbs@pbs1.canje.net:pve1' failed: exit code 255

The datastore has the same configuration as the original host:
zfs set xattr=sa dnodesize=auto dpool/data zfs set acltype=posixacl dpool

Following the log from pve host:

Same issue with my system. I tried to restore a lxc and got this error:

restoring 'pbsbackup:backup/ct/1100/2021-03-26T00:41:02Z' now..
Error: error extracting archive - error at entry "": failed to apply directory metadata: failed to apply acls: Error while restoring ACL - ACL invalid

I can't restore any lxc because always get this error.

I'm running PBS 1.0-11 and PVE 6.3-6

Edit: Older backups (before march 24th) work fine but i. e. new basic backups from new CT even don't work.

I can't restore some of my lxcs because this error appears, others don't.

Hi.

I got the same error message after trying to restore one CT.

Code: 
unable to restore CT 604 - command '/usr/bin/proxmox-backup-client restore '--crypt-mode=encrypt' '--keyfd=8' ct/602/2021-04-01T01:30:57Z root.pxar /var/lib/lxc/604/rootfs --allow-existing-dirs --repository root@pam@xxx.xxx.com:backups' failed: exit code 255

Same PBS and PVE versions ( PBS 1.0-11 and PVE 6.3-6)


EDIT: I tried to restore an older backup from the same CT, and it worked. So I guess there must be an error creating backups on newer PBS versions. I cannot confirm which PBS version was used when I created this backup, but it was made on March 21th (and I always keep PBS software updated, so maybe anyone can trace it out).
