Hands-on how-tos for Proxmox Backup Server.
Short, practical walkthroughs for connecting Proxmox VE to a hosted PBS, setting up replication, enabling immutability, running restores, and keeping verify/prune healthy.
What’s inside
Do it fast, then verify.
- Add hosted PBS targets and run the first backup
- Remote Sync offsite with verify scheduled
- Immutability via snapshots + WORM/object-lock
- Restore VMs, CTs, and files with validation
- Monitor verify/prune/GC with alerts
