[PVE-User] Backup Issue

[David Thompson]

Hi all,

I'm having an issue with my backups all of a sudden. The server has been backing up for months without an issue. All of a sudden I am getting errors with the backups. I have snipped some of the errors as the log file is just to massive to include in this email. The error seems to be on only on 2 Containers. All other containers (approx 12) are fine as are the KVM servers.

I thought it might be a RAID issue. The RAID is built as a RAID 10 with 4 drives running off of an Adaptec RAID card 6805 series. It doesnt show any errors at all on the card, so I'm not sure its the card.

I rebooted the entire host over the weekend and ran the first backup of all guests by adjusting the time, and it ran perfectly fine. I then set it back to its normal backup time throughout the evening and it failed again as usual.

The PVE Version is:
pve-manager/2.2/3089a616


Does anyone have any idea why this backup is failing all of a sudden?
