rdiff-backup keeps a normal uncompressed copy of every file.
Compression is only used for maintaining the history of the file

So you need to put your backup destination on a compressing
filesystem.  I've never tried that with linux and have no

Metadata is maintained by default.

rdiff-backup sends a rsync like set of deltas from the source computer
to the backup computer.  The previous backup is then used to create a
new backup by applying those deltas.  And a reverse delta is created
and maintained that allows the current backup to be reverted to
historical versions.  I'm not sure if that satisfies your desire or

I don't think you have any control of the process.

I keep a local rdiff-backup of my files and a remote copy.  I rsync
the local copy to the remote.  rsync has lots of options for how that
is done.  If you want details, I can give you my command line for

You get a increment every time you call rdiff-backup.  So use cron to
invoke it daily.  If there are no changes between calls, then your
backup won't be modified.

note: I have a nightly backup script which invokes rdiff-backup.  It
does several other things, so it is my backup script I call from cron,
not rdiff-backup directly.

note2: There are some scripts running around that read rdiff-backup
logs and statistics and email you a nightly summary.  I do that for
each of my machines I backup.
