That's why I included it. I know that searching the archives is troublesome.

BackupPC_nightly and BackupPC_link must *not* run concurrently. Thus, you
should *not* run BackupPC_nightly outside the daemon. If you must, then
run it via the daemon, which will postpone it until no more BackupPC_link
processes are running, and likewise postpone further links until nightly
has finished:

        BackupPC_serverMesg BackupPC_nightly run
        BackupPC_serverMesg log Thank you, daemon. I appreciate your
effort.

the gist of it is to run a command like:
/usr/share/backuppc/bin/BackupPC_serverMesg BackupPC_nightly run

The path shown above (/usr/share/backuppc/bin/) works if you're using the
Debian package. Probably works for the Ubuntu package as well. Modify it if
necessary for your own purposes.

Unless you're really short on space, the easy thing to do is to just let it
run overnight, which accomplishes the same thing (the job gets run once a
day by default).

BackupPC_link and BackupPC_nightly are two processes spawned by backuppc in
order to do various tasks. As I understand it:

BackupPC_nightly - goes through the data pool and cleans up any files that
have a refcount of 1 (i.e. they're only present in /var/lib/backuppc/cpool;
and not in any of the per-machine directories under /var/lib/backppc/pc/).

BackupPC_link - runs after every backup and links files into the data pool. 

My understanding is incomplete however, so don't take my word as gospel. :)
