Ah, good catch. I didn't double-check that. I just tend to check shadow and
gshadow when I change passwd and group, in case I forgot something. (I
forget a lot).

That's why I suggested checking the whole filesystem right away.

'chown backuppc: <filename>' will set the group to whatever the default
group of the backuppc user is. This may or may not be desireable in all
cases, but it does save some keystrokes when it is desired.

In any case, it is wise to try these sort of things out on a limited area if
at all possible, and read the manual page before getting too fancy.
