Dan,

do you have bonnie++ installed? Would you please benchmark your 
filesystems with:

bonnie++ -u root -f -n 10:0:0:1000 -s0

And post the file creation results? Thanks a lot!

Additionaly it would be very interesting to get your inode creation rate 
while incremental dumps are running:

cd /path/to/your/backuppc/storage
while true; do df -i -P . |tail -1| awk '{print $3}'; sleep 10; done

Christoph
