[SOLVED] Backup ownership problem backup@pam vs root@pam, deleted old versions, multi terabytes transfers

[carsten2]

I minimize data transfer over the internet (multi terabytes), I backed up all VMs to a second PBS while this PBS server was on the local intranet.
Then I moved the server to a another location and want to sync the backups from the main site to this remote site. However the sync job gives errors like:

 sync group ct/103 failed - owner check failed (backup@pam != root@pam)

Also it seems that it does not transfer only differences but the whole VMs (resulting in multi terabytes transfers) and also it seems to delete the old versions of the backup which had root@pam as the owner.

How to ensure, that the old backups are kept and only differences are transfered?

The setup is as follows
* local PVE Cluster with pve1 and pve2 which replicate the VMs between the to servers.
* local PBS to which the cluster VMs get backuped
* two remote PBS which should sync the backups from the local PBS

you can manually change the owner (it's in the file called 'owner' in the backup group dir). see https://bugzilla.proxmox.com/show_bug.cgi?id=2847 https://bugzilla.proxmox.com/show_bug.cgi?id=2864 for related tracking entries

Thanks. Now the error is gone.

It still seems that the the container package (2GB) is transfered in total every time. Is this correct? Should't it be a differential transfer?

post a full log, it should indicate what's going on.

By again checking the data transfer with iftop, it seems to transfer 378MB instead of 2GB so it seems to be differential. Is there any means to see the data transfer by in the job or GUI?

you can look at the backup log on the PVE side, and the corresponding task log on the PBS side
