How-to

Add a hosted PBS target to Proxmox VE.

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

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. Confirm the snapshot. In PBS, confirm the new snapshot appears after the job completes.
  6. Schedule regular backups. Set the backup job timing and retention per your policy.

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 timing and retention plan

Quick checks

  • Storage shows Active in Proxmox VE.
  • Initial backup finishes without fingerprint or auth errors.
  • Snapshot appears in PBS after the job completes.
  • Retention matches your policy.

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.
