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
