I have yet to see someone mention ZFS in this discussion, so there. I said it. We're currently testing FreeBSD7.0-BETA1.5 on a HP DL380/StorageWorks 30 with 2TB (expandable to 4TB) in raidz. This will be the main backup server which is located in the same room as the servers. This will then use zfs send|get with another backup server running the same ZFS-version in a remote location. And, it can also be used with iSCSI (snapshotting) which makes backups easypeacy. ZFS eliminates the need of fancy RAID-controllers, too. You just need disks. And lots of 'em. If you can; stay put a few more months and wait eagerly on ZFS/7.0 to become STABLE :-) At least, that's what I would (and will) do. -- Håkon
