Hi, if i had to decide what to do, i would do both, a) and b). Why? you won't beleave it, but a few weeks ago at one of our customers 2 of 3 drives in a scsi raid5-array died in a periode of half an hour. They where more then happy having all their data on tape, and back on a replacement-disk in about 4 hours. Amanda rocks.... But it was a hard fight to convince them to do backups parallel to their raid-5 array. Their argument: why backup, we have raid.... Christoph
