Anyway, I'm preparing a separate test setup now, to be able to do
correct tests (so both BackupPC and an rsync tree are using data from
the same time).
Test results will be here tomorrow.

But I don know that BackupPC does use more bandwidth.
Besides: when dumping a full backup, the 'pool' means (I hope): file
already in pool, using it. If not, then there is a problem, as those
files are already in another backup set of the test host. But BackupPC
pulls them over anyway.

The problem ain't the backup server nor it's speed. The problem is the
data transfer.

And I have set up BackupPC here 'as-is' in the first place, but we saw
that the full backups, that ran every 7 days, took about 3 to 4 days to
complete, while for the same hosts the incrementals finished in 1 hour.
That's why I got digging into the principles of BackupPC, as I wanted to
know why the full backups don't works 'as expected'.
