Sanoid is a policy-driven snapshot management system for ZFS that automates creation, rotation, and health checks of snapshots across datasets. You describe retention in human terms—hourly, daily, monthly, yearly—via simple templates, and Sanoid enforces those rules consistently without manual cron gymnastics. It sets and respects ZFS properties, places holds to protect in-use snapshots, and surfaces health issues so you notice problems before recovery time.

rsnapshot is a filesystem snapshot utility for making backups of local and remote systems. It leverages rsync and hard links to create efficient incremental backups, allowing users to maintain multiple backups without consuming excessive disk space.​

...Because it uses native Btrfs primitives, restores are fast and space-efficient, and replicas can be mounted instantly for inspection. Clear logging and dry-run modes make it safe to adopt in production while giving operators visibility into every snapshot and transfer.

OpenSANd is a server system that allows access to disk storage over the NBD protocol. It is designed to work particularly well with VirtualControl and thus allow KVM machines to use disk partitions over Ethernet, similar to expensive, commercial SAN systems using FibreChannel or iSCSI.

rsnapshot is a filesystem snapshot utility based on rsync. rsnapshot makes it easy to make periodic snapshots of local machines, and remote machines over ssh. The code uses hard links whenever possible, to greatly reduce the disk space required.

narc provides simple and efficient "snapshot-like" archiving of a file hierarchy over time on any Unix-like filesystem that supports hard links.
