ZFS snapshots on Proxmox make VM backups instant, consistent, and space-efficient.
A single command like zfs snap pool/vmdata@backup lets you capture a full system state you can roll back to in seconds — no downtime, no duplicate data.
Efficiency, reliability, and simplicity—built right into ZFS.

Turn on fast, transparent compression with zfs set compression=lz4 pool/fs
lz4 compression saves space without slowing down your workloads — giving you more efficient storage and better performance, automatically.
Simple command. Big impact.
