10 GB, really? That means you are running a 64-bit system and you have *a lot* of RAM. How much *do* you have, and which column of 'ps' output are you quoting? I wouldn't be surprised at all if the cause of the process dying is an 'out of memory'. Is your system swapping?

Honestly, the fact that you don't have an answer to this comment before asking your question below irritates me. > > Also, if you haven't already checked you might want to be sure that no > > other backups are running at the same time as the one having problems. > > Is there a nice way to achieve that with BackupPC ? That has been answered, but really, 10 GB for one backup process feels wrong. Having concurrent backups running would make things even *worse*, but *not* having them running doesn't fix it. You also haven't told us if you actually are using rsync, or in what order of magnitude the number of files you are trying to backup is.
