Backing up Citrix MetaFrame server

Re: Experience with VXA drive Retro 4.2?

I promised an update on Retrospect over my 10Base-T network. In a word: slow. I don't have the exact figures with me, but we're peaking at about 60 MB/min. over 10Base-T ethernet. The good news is that's really all you can expect from 10Base-T -- and most of the Macs at home don't support 100B

Time for backup at home

Much as I'd love to put a VXA or AIT drive on my home network, I don't want to spend that much money on the drive. I've had enough bad experiences with DAT and DAT-II drives that I've ruled out that option. It seems to be coming down to NS-20 and Onstream ECHO 30. DRIVE NS-20 ECHO 3

Re: AIT tape loaders-any real world experiences?

I have a different solution: two AIT drives. 1. If one drive fails for some reason, you can still run backup and do restores. 2. You can always have a blank tape in the second drive just waiting until it's needed. 3. You can double overnight and weekend backup with two tapes. 4. You're not d
