zfSnap is a simple sh script to make rolling zfs snapshots with cron. The main
advantage of zfSnap is it's written in 100% pure /bin/sh so it doesn't require
any additional software to run.

zfSnap keeps all information about snapshot in snapshot name.

zfs snapshot names are in the format of Timestamp--TimeToLive.

Timestamp includes the date and time when the snapshot was created and
TimeToLive (TTL) is the amount of time for the snapshot to stay alive before
it's ready for deletion.
