On a debian or ubuntu system the data is held in /var/lib/backuppc/. Under
that directory, the pool/ directory has the hashes of the uncompressed data,
the cpool/ directory has the compressed data.

I'm guessing you're not on a Debian system (or at least you didn't install
from a debian package), so I don't know where yours might be. I believe by
default the data will be compressed, so If you don't explicitly specify in
the configuration file for that host (or change the default value in
config.pl) that you want your data uncompressed, it's probably compressed.

For instance, I have a file /etc/backuppc/localhost.pl with the following
entry in it (among others):

# turning off compression on these files, so they can be recovered without
# backuppc.
# wouldn't make sense to need your backup server, 
# in order to recover your backup server, now would it?
$Conf{CompressLevel} = 0;


So all the backups of files from the BackupPC server itself, are kept in
/var/lib/backuppc/pool. (Of course they're also linked to
/var/lib/backuppc/pc/localhost so they can be found by name as well). (In
case you're wondering, I put the BackupPC data pool on its own disk so if
the OS disk dies the backups are likely to still be good, and if the data
disk dies there is the OS disk there to help recover it).
