hmm.....  can you send me the output of dumpe2fs /dev/sdXX?  You can
run that command while e2fsck is running, since it's read-only.  I'm
curious exactly how big the filesystem is, and how many directories
are in the first part of the filesystem.

How big is the filesystem(s) that you are backing up via BackupPC, in
terms of size (megabytes) and files (number of inodes)?  And how many
days of incremental backups are you keeping?  Also, how often do files
change?  Can you give a rough estimate of how many files get modified
per backup cycle?

Thanks,
