with BackupPC, using the web interface, it's much the same, because it lets
every backup appear "filled" even if it isn't. Navigating the file system
under $topDir, BackupPC's file name mangling poses a further difficulty that
your script avoids. BackupPC needs it for pooling files with different
attributes (what does your script do if file attributes change?).

For the record: making hardlinks to files does *not* consume inodes. It adds
further directory entries pointing to the same inode. The only problem is that
file link counts are limited to something like 32000 (your file system may
vary), so you will eventually have a problem (in about a hundred years, if you
do no further pooling).
