Hi, I have newly setup ON 7.2 private cloud (all hosts Debian 12), with few test VMs and Restic backup. Now I have a problem which could be a software or setup bug. For VM#1 (on on-node11.lcl KVM host) imported from oVirt both full and increment backup works. Another VM#2 (on on-node10.lcl KVM ho…

Just made successful incremental backups of 2 other VMs running on the same KVM host.

Hi Andrei, Thanks for the additional logs. After comparing the working and failing VMs, this does not appear to be a Restic issue or a general OpenNebula backup subsystem issue. The failing VM (#30) has a different disk layout from the working VM (#40). In particular, disk.0 is an absolute symlin…

[image] Dmitrii: The failing VM (#30) has a different disk layout from the working VM (#40). In particular, disk.0 is an absolute symlink: Hi, so this is possibly an issue with VM creation code generating wrong link format.
