Pakket: simplesnap (2.1.0)

Simple and powerful network transmission of ZFS snapshots

simplesnap is a simple way to send ZFS snapshots across a net‐ work. Although it can serve many purposes, its primary goal is to manage backups from one ZFS filesystem to a backup filesystem also running ZFS, using incremental backups to minimize network traffic and disk usage.

simplesnap it is designed to perfectly compliment snapshotting tools, permitting rotating backups with arbitrary retention periods. It lets multiple machines back up a single target, lets one machine back up multiple targets, and keeps it all straight.

simplesnap is easy; there is no configuration file needed. One ZFS property is available to exclude datasets/filesystems. ZFS datasets are automatically discovered on machines being backed up.

simplesnap is robust in the face of interrupted transfers, and needs little help to keep running.

Unlike many similar tools, simplesnap does not require full root access to the machines being backed up. It runs only a small wrapper as root, and the wrapper has only three commands it implements.
