I haven't touched the rsync-in-perl code and don't know anything about
it but I can say that the hashing/pooling code (and the whole nature &
structure of attrib files) is pretty straightforward. I have gotten
pretty deep in the code from the routines I have written to check/fix
the pool and to delete individual files and directories (correctly)
from one-or-more incremental or full backups. The code for playing
with the pool is all very straightforward.

I agree - I think the ideal combo would be:
- Pooling & compression like with BackupPC (though I would add full
md5sum checksums which you would get anyway I think if we upgrade
to protocol 30)
- Database backend like Bacula (this would get rid of the platform
dependence of hard links along with all the associated limitation
and backup issues caused by them; plus, it would make it much
easier to extend to allow backup of acls, extended attributes, and
any other filesystem entry needed to accurately recreate the
backup)
- Choice between simpler server+rsync method like BackupPC (for SOHO
or personal use) vs. more sophisticated client/server approach of
Bacula
- Modular code that would allow extensions (e.g., alternative
compression algorithms, encryption)
- Choice of interfaces:
web
fuse fs
other modular extensions
- Knowledge of and ability to create full restorable backups of
multiple filesystems (including shadow copies for NTFS and other
ntfs tidbits)

It is fine for small numbers of files and poking around. Certainly
faster than navigating the CGI interface ;)
