Mark,

That is a pid 10878; you can use the command:

# lsof

to see all of the files and threads open on your system; piping to grep for
pid # or process name.

This is a root owned rsync --server process, as you said associated with
backuppc.  Not a lot more to talk about?
But if you would like to, why not address those questions to the correct
source:

https://lists.sourceforge.net/lists/listinfo/backuppc-users

Mark Sanborn describes the use of rsync for incremental backups:
