  4. Can I delete a dir from inside a .vma file?

    I have a VM backup that I want to restore, a .vma.lzo file. This file is huge because of an out-of-control process. Can I delete a dir from inside a .vma file and then restore the VM? Restoring the entire VM with all the unneeded data inside would take up way too much time.

  8. [SOLVED] Backup causes ZFS: arc_reclaim/arc_prune to nearly freeze system

    Hi, I'm have a backup-job scheduled which will daily backup my system. Sometimes while running the backup, the system will spawn one arc_reclaim and lots of arc_prune processes. All of these processes will eat up the CPU time and cause the VMs which are still running to run into (timeout)...
  9. Proxmox VM backup vs. wbadmin vs. [...]

    Hi, until now I've used wbadmin to backup Windows machines (no matter if VM or on real hardware). But now I've setup a Proxmox test machine and I've found the integrated VM backup feature which looks very interesting to me. Did a short test with a Linux guest, which worked flawlessly. But I...

  13. QMrestore confusion

    Just looking for a bit of knowledge confirmation. I've been using vzdump to take nightly snapshot backups of my VMs. My only question here is that it seems like you cannot restore a snapshot backup to an already existing VM ID.

  16. Backup to samba when the mount fails

    But mounting the remote backup folder via fstab has one danger. If the remote system goes down, the remote folder won't be automounted again after the remote machine comes up again. So the backup will be dropped to the local folder which is used as the mount point. If this folder is on the...
