So let me add some more detail, I have a hot swap disk cage that currently
has my backup data on it almost all of them are in VM's.  That disk is my
primary data disk, all I need/want to do is to copy that data periodically
to another disk that I then can rotate offsite, so I will have 2 more disks
and will swap one in and out then during the night either copy or rsync the
data to the offsite disk, rinse, wash and repeat....I have plenty of cpu,
16cores and lots of memory 32Gig....so this disk will not be my primary
backup disk but just my offsite disaster recovery in case the other one ever
bites the dust...
