When you upgraded from scratch, did you change CPU architectures? IE, from 
i386 to amd64? If so, you've just learned that rrdtool produces CPU-specific 
files.

Copy /var/lib/backuppc/log/pool.rrd to a server of the same architecture as 
your old server. Run:

rrdtool dump pool.rrd > pool.xml

Then copy pool.xml back to your new server and run:

rrdtool restore -f pool.xml /var/lib/backuppc/log/pool.rrd
chown backuppc:backuppc /var/lib/backuppc/log/pool.rrd
chmod 640 /var/lib/backuppc/log/pool.rrd
