Hello,
I’m running Proxmox VE and Proxmox Backup Server in a non-enterprise lab environment and I’m looking for guidance on safely restoring or reinitializing my PBS setup after a host recovery.
Environment
Thank you for your time and for maintaining Proxmox — it’s been invaluable for learning and lab use.
Best regards,
Tom
I’m running Proxmox VE and Proxmox Backup Server in a non-enterprise lab environment and I’m looking for guidance on safely restoring or reinitializing my PBS setup after a host recovery.
Environment
- Proxmox VE 8.x
- Proxmox Backup Server running as a VM
- No enterprise subscription (lab use only)
- PBS datastore backed by a Synology NAS (NFS)
- Previously part of a 2-node PVE cluster (now dismantled)
- One PVE host experienced hardware and networking failures
- Cluster quorum issues occurred and the cluster was ultimately dismantled
- PVE hosts were reinstalled and VMs restored successfully
- PBS VM still exists, but backup jobs and/or datastore access are no longer functioning correctly
- Backup tasks appear stuck or inconsistent after the downtime
- Most VMs are running and data is intact
- PBS VM boots
- Datastore exists but backups are not behaving normally
- I want to avoid corrupting the datastore or orphaning snapshots
- I would like to be able to restore some of the VMs from the PBS datastore that I am not currently able to add to my new PBS instance.
- Recommended steps to:
- Validate PBS datastore integrity
- Determine whether datastore metadata should be repaired, reattached, or recreated
- Safely resume backups from Proxmox VE
- Guidance appropriate for a lab / non-enterprise setup
Thank you for your time and for maintaining Proxmox — it’s been invaluable for learning and lab use.
Best regards,
Tom
