Learn Proxmox Backup Server - Pre-Requisites Skill & Setup Environment
Before touching Proxmox Backup Server, you need to master Linux administration (network, storage, services), understand the backup concepts as well as Proxmox VE basics, and prepare the right software and hardware: PBS 4.2, ZFS/LVM/NFS storage, and Proxmox VE 8.x/9.x clients. In this episode you will also verify that your entire environment is ready for backup.

Learn Proxmox Backup Server - History, Background & Why You Need It
This episode traces the origins of Proxmox Backup Server: a project started by Proxmox in 2018 with the first stable 1.0 release in 2020 as the backup backbone of the Proxmox VE ecosystem. You will also understand why PBS is needed — per-chunk deduplication, client-side encryption, instant restore, native integration, off-site sync, and its role as a Veeam/Bacula target.

Learn Proxmox Backup Server - Core Concepts & Key Architecture
This episode dissects the Proxmox Backup Server architecture: the datastore as the home of chunks, content-defined chunking for dedup across backups, and backup groups and snapshots per VM/CT/host. You will also understand the supporting components — the proxmox-backup server, the web UI on port 8007, the proxmox-backup-client CLI, and the API — plus its integration with the PVE datacenter.

Learn Proxmox Backup Server - Installation & Initial Configuration
This episode guides you through installing Proxmox Backup Server 4.2 via the ISO installer or the apt repository, disk and ZFS selection, and network and hostname configuration. You will also create the first datastore with GC and verify schedules, then understand the user realm options — PAM, AD/LDAP, and Proxmox VE — before adding the first user.

Learn Proxmox Backup Server - VM/CT Backup from Proxmox VE
This episode guides you through integrating PBS into the Proxmox VE datacenter: adding PBS as storage via Datacenter → Storage with the server, datastore, and certificate fingerprint. You will also choose the backup mode (guest agent, snapshot, suspend, stop), schedule regular backups from PVE, and verify that snapshots appear in PBS.

Learn Proxmox Backup Server - Restore VM/CT & File-Level Recovery
This episode covers the most important side of backup — recovery. You will fully restore VMs/CTs to the original PVE or a different node, use the file restore feature to grab individual files without a full restore, and perform file recovery and boot testing of restored results to ensure your RTO is met.

Learn Proxmox Backup Server - Deduplication & Garbage Collection
This episode dissects PBS efficiency: content-defined chunking that produces dedup across backups and VMs, and how to read the dedup metrics in a datastore. You will also understand the prune (retention) then garbage collection flow to delete unused chunks, and schedule GC so your storage does not balloon.

Learn Proxmox Backup Server - Client-side Encryption
This episode secures backup data with client-side encryption: creating a base64 key on the client side, pointing it to PVE/PBS backup tasks, and verifying that the server only stores unreadable ciphertext. You will also learn proper key management — because without the key, restore is impossible.

Learn Proxmox Backup Server - Retention & Prune Policy
This episode manages the snapshot lifecycle: the prune policy with keep-last, keep-daily, keep-weekly, and keep-monthly per backup group, and how sync jobs maintain retention on the remote side. You will learn to align retention with RPO/RTO targets and verify prune results so the datastore stays healthy.

Learn Proxmox Backup Server - Verify & Integrity Check
This episode ensures stored snapshots do not silently corrupt: scheduling a verify job that re-reads and validates every chunk's checksum, using the verify-new option for new snapshots, and performing integrity audits via task logs and datastore checks. A backup that corrupts undetected is a disaster waiting to happen.
