as Adam pointed out, block device is block device.

Actually, you can get what you want along this path too. - vgextend your VG to include the RAID device - pvmove your backup LV off the current disk onto the RAID device - vgsplit your backup LV out of the current VG into a new one. The benefit is that you can - in theory - do all of this without stopping BackupPC and unmounting the file system, even during running backups. It probably wouldn't be good for performance, so you'd preferably choose a period of time when BackupPC is idle :). If you're familiar with LVM (and want to keep your pool file system in a LV as opposed to on the RAID with no LVM in between), this gives you slightly more protection against user errors. 'dd' won't complain if you accidentally swap source and destination device, with LVM this can't really happen. If you lose power during the copy operation (pvmove), LVM should be able to resume where it was interrupted. On the other hand, the 'dd' approach is simpler, and you get to keep a working backup of your pool. If in doubt, stick with 'dd'. > I hope someone works out a way to add the above to the wiki, I agree with that part :) ["the above" referring to Adam's message]. > in a more meaningful/less wordy way. There was nothing wrong with your explanation. I'd prefer correct content over well-written content in the wiki any day - not meaning to imply yours was not well-written.
