Storage.... 4x2TB Seagate's in a ReadyNAS NV+. NetGEAR's "RAID-X" system, pretty much a basic RAID 5 setup, 6TB storage.
6x500GB in the PC i'm using.. RAID 10 configuration. 1.5TB storage space.
Critical stuff on a external 1TB WD drive thats only used for adding or removing stuff from the drive, and spends the rest of the time shut down.
And of course... Duplicate CF's for the Amiga it self.
But i got no real backups.
