Proxmox Backup Server: Backup for your Datacenter

on YouTube ↗16m

" summary

Proxmox Backup Server stores backups as content-addressable storage of millions of cryptographic-hashed chunks, enabling efficient deduplication and fast incremental VM backups by tracking changed blocks and reusing unchanged chunks. File and container backups use variable-size chunking and a metadata/payload split to avoid rereading unchanged payloads. Offsite sync jobs (pull today, push coming) and scheduled prune plus two-phase garbage collection with a 24h atime grace reclaim space. Also offers LTO5+ tape support, verification jobs and protected snapshots.
