How does the size of cpool compare to pc/host_name?   Basically all
files under the cpool tree should be hardlinks to files in a
pc/hostname/backup_number directory, and BackupPC_nightly should
remove anything that does not have at least 2 links.   If cpool is
substantially bigger, then something is wrong with BackuPC_nightly (a
possibility also indicated by the error messages...).    If your
pc/hostname tree is also that large, then the target must have had
additional filesystems mounted when the backup was taken or perhaps
filesystem corruption that caused some sort of directory recursion
loop.
