zrepl, automatic ZFS snapshots and replication, protecting your filesystems from first boot.
zrepl is an open source ZFS snapshot management and replication daemon. It takes automatic periodic snapshots and replicates them between datasets and machines with configurable pruning, giving you dependable, filesystem level backups and disaster recovery for ZFS.
cloudimg ships zrepl hardened and fully patched on Ubuntu 24.04 LTS, preconfigured with a ready to run demo pool and a local push job so snapshot and replication work out of the box, with no shipped credentials. 24/7 support is included with every image.
