      I recently started getting the below error on one of my VMs. It was backing up just fine and now it errors out every time and won't create any new snapshot or backup. If I remove the snapshot that the backup creates, it behaves differently. It will create a new snapshot and has green for the backup but then still errors out with the same error. I'm unsure of what's going on and googling has been no help. I have no issues on the backup health tab. All other VMs back up without issue. I've never cloned this VM or done anything with the disks.

      Whole error on every backup unless snapshot is manually removed:
      Start: 2024-12-19 05:21
      End: 2024-12-19 05:21
      Duration: a few seconds
      Error: _removeUnusedSnapshots don t handle vdi related to multiple VMs

      Whole error when I remove snapshot then backup:
      Snapshot (successful)
      Start: 2024-12-19 20:06
      End: 2024-12-19 20:06
      Backup (successful)
      transfer (successful)
      Start: 2024-12-19 20:06
      End: 2024-12-19 20:26
      Duration: 20 minutes

        @SudoOracle Can you try recreating the backup job? It won't clean up the previous backups, but it may kick off a new process. Also, (I'm sure you are, but just double checking) are you on the latest XO(A)?

          I am running the latest XO. I ended up fixing the issue, it has backed up successfully 2 times now without any errors. What I did was removed ALL snapshots for the specific VM. Once the tasks finished for removing the snapshots, I created a new manual snapshot. Then let the backup happen as normal. What I noticed though is the backup snapshot replaced my manual snapshot so the VM still only has 1 snapshot. But it seems to be working now.

            We ran into the same issue as well. We removed ALL snapshots of this vm and then it started working again. Comes at a cost since we had to remove the non-backup-related snapshots as well...
