Hi Matthew, I don't think the concern is so much that a client computer's drive and one of your backuppc box's drive would fail at the same instant, but rather what the cost of one drive in the backuppc box's drive would be. Loosing a single drive if you pool them all together with LVM means you loose the entire logical volume, which means you have to start all backups over again from scratch. That's too much of a waste of resources to me (particularly if you are using rsync.) but that is just my perspective, it may be perfectly acceptable in your environment, and is a decision you have to make.
If you go the RAID 1 option, I'd create two RAID 1 arrays and LVM them together, or perhaps look at the RAID 10/0+1 option and put all 4 drives in the same array. I still think that I would use LVM since it gives you some flexibility in the future. Red Hat's new LVM guide is pretty decent, gives lots of real world examples, you may want to check it out as well.
