How-to

Add a hosted PBS target to Proxmox VE.

Connect your cluster to a dedicated Proxmox Backup Server, add the datastore, run a backup, and verify the snapshot.

Steps

  1. Get PBS credentials. Collect the PBS hostname/IP, datastore name, username (token recommended), and password/token.
  2. Trust the PBS fingerprint. In Proxmox VE UI, go to Datacenter > Storage > Add > Proxmox Backup Server, enter the endpoint, user, and hit Fingerprint to approve.
  3. Add the datastore. Select your PBS datastore, name it, and enable Content: VZDump backup file. Save.
  4. Run a test backup. Create or use an existing backup job targeting the new PBS storage. Run once and confirm it completes.
  5. Verify the snapshot. In PBS, check Verify for the new snapshot, or trigger a manual verify to confirm integrity.
  6. Schedule regular backups. Set the backup job schedule and retention per your policy (daily/weekly/monthly) and align with prune/GC windows.

Prereqs

  • PBS hostname/IP reachable from Proxmox VE
  • PBS user or API token with datastore access
  • Datastore name (case sensitive)
  • TLS fingerprint ready to trust
  • Backup window and retention plan

Quick checks

  • Storage shows Active in Proxmox VE.
  • Initial backup finishes without fingerprint or auth errors.
  • Verify completes in PBS for the new snapshot.
  • Retention/prune matches your schedule.

If something fails

  • Re-approve the PBS fingerprint and retry.
  • Confirm user/token permissions include the datastore.
  • Check time sync (NTP) between PVE and PBS.
  • Review firewall rules for 8007/backup traffic.
