zfs-auto-snapshot: An alternative implementation of the zfs-auto-snapshot service for Linux that is compatible with zfs-linux and zfs-fuse. Automatically create, rotate, and destroy periodic ZFS snapshots. This is the utility that creates the @zfs-auto-snap snapshots if it is installed. For this version, the different labels (e.g. frequent, hourly, daily, weekly, monthly) are applied as the zfs property com.sun:auto-snapshot-label. This program is a posixly correct bourne shell script. It depends only on the zfs utilities and cron, and can run in the bash shell. It has been adapted slightly to run under FreeBSD, but aside from the location of bash itself and of getopt, it should work on other systems.
