You modified topdir in config.pl and mounted your external drive in
the wrong location. Basically you can't modify topdir in the config.pl
(at all if you are using a package installed version of backuppc). To
solve your 1st problem, umount the drive from /media/BackupPC and
mount it on /var/lib/backuppc and revert the change in config.pl. That
should fix the pooling issue.

2nd possible problem, make sure you exclude /var/lib/backuppc from
your localhost backups, or configure to only backup a single
filesystem at a time.

3rd problem, broken graphs - I'm not sure if this is related to the
above, but fix the first two problems, and then look through the log
files to find an error message relating to the graphs and we should be
able to help further.

PS, if you installed from source code, then please ignore almost
everything I said above, but in either case, read the wiki for how to
change the topdir correctly (there are methods for both building from
source and installing from a package).


Regards,
Adam
