= Obsessive copying disorder ?? After a major 2x drive loss last year I decided to "up the stakes" or perhaps lower them, with a very extensive backup strategy. Here's what I have, tell me I didn't go TOO far Mac Pro system : 1x Complete system drive clone. 2x Samples/data drive clone 1x Audio/project drive clone 1x TM backup of all three across 2 x 3tb drives ( 2 x TM copies ) MBP system : 1x CCC of system drive 1x TM backup of system drive 1x Mac Install ESD on 16gb thumb drive 1x original apple 750gb Lion system ( outdated but also bootable ) Clones I will update when new programs / data added, once a month. TM backups end of every day on both systems. How's that sounding ?? Marty.
