zfs-auto-snapshot script creates automatic snapshots of all zfs filesystems and volumes.
The script will automatically rotate snapshots deleting old ones.
The script will temporarily avoid backups on damaged pools or pools with scrubbing going on.
It creates:
4 snapshots per hour to rotate every 15 minutes
24 hourly snapshots
30 daily snapshots
12 weekly snapshots
12 yearly snapshots
Script has been tested on zfs on linux 0.8.3, centos 7
Original script from https://github.com/zfsonlinux/zfs-auto-snapshot
