How big does a single archive have to be? I'm somewhat fanatic about keeping it on a single disk myself so that I can software-mirror to a drive that is rotated offsite. My current version is using one of these: http://www.startech.com/Product/ItemDetail.aspx?productid=HSB320SATBK&c=US replacing the 2 5" bays in a desktop machine with 2 disks permanently mirrored and a pair of extra drives that I rotate in the 3rd slot. The OS runs on separate internal drives. I also have a USB->SATA adapter so I can mount the offsite drive in a laptop if needed for immediate access. I'm using 750 gig drives now because they are cheap and will complete the mirror copy in a couple of hours, but you could go to at least a gig on a single drive these days - and you avoid the overhead of raid5 this way. > Running BackupPC as a Xen guest has the advantage that you can use > resources of the server better - as IO on the SAN holding backup is a > bottleneck, you still have plenty of CPU on a Xen server for running > guests which are not busy most of the time. I can understand that for software that is complicated to install, but backuppc is a perl script and a couple of CPAN modules... > An you can easily migrate the guest to another (stronger) machine, > without any downtime or service interruption. But it's not hard to do that with the base software either - you just need to have the archive self-contained and the ssh key for the backuppc user available. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
