BackupPC puts substantial additional load on disks, because it forces them
to seek every file, and on a heavily fragmented filesystem this can add up
to a lot of head movement which would normally not take place.
So a drive which might have been marginal before, might fail when you do the
backup of it.
I've had this happen to me once or twice (once with disastrous consequences
when I found that the new external drive enclosure I was using for the backuppc
data pool was no good, so I lost the backup that caused the client disk to
fail, and then discovered that the LVM RAID I had been using to give me a
redundant client disk had stopped replicating a year before and not given me
any signs I recognized... fortunately it was only my own data, and not
someone else's that I lost).
So be aware that this can happen.
