Automatically create, rotate, and destroy periodic ZFS snapshots. This is the utility that creates the @zfs-auto-snap_frequent, @zfs-auto-snap_hourly, @zfs-auto-snap_daily, @zfs-auto-snap_weekly, and @zfs-auto-snap_monthly snapshots if it is installed.

This program is a posixly correct bourne shell script. It depends only on the zfs utilities and cron, and can run in the dash shell.
