Hi there,

In my BackupPC, the rrdtool doesn't seem to be properly integrated.
It shows a pool size of 1.4 TB. However, there are 7.7 TB on the
disk in /var/lib/backuppc/pool.

  7,7T    /var/lib/backuppc/pool

According to your graphs you have about the right amount of data in
'cpool' and you are no longer using 'pool' - presumably because you
changed from an uncompressed to a compressed pool.  You will need to
remove the content of 'pool' manually if you no longer need it.

It also shows 100TB as total capacity but I'm poor, have only 10TB ??

The largest value on the graph's vertical axis doesn't show you how
much space you have on the pool filesystem.  RRDtool scales the graph
to accommodate the red line, which shows the total amount of all the
data backed up on all the clients *before* pooling and compression.
To me it looks correct.

In addition it is shown twice in the backuppc homepage (see attachment).

I'm running Debian 11 with Backuppc 4.4.0-3 and rrdtool 1.7.2-3+b7

I don't know what you've done to deserve that.  It may take a little
sleuthing.  In the first instance perhaps you can save the status page
as an html file and let us see that?  There might be clues within.
