rsync - Dec 2012 - [Bug 9498] New: Feature request for extending --backup-dir functionality

https://bugzilla.samba.org/show_bug.cgi?id=9498

           Summary: Feature request for extending --backup-dir
                    functionality
           Product: rsync
           Version: 3.1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: do1 at yandex.ru
         QAContact: rsync-qa at samba.org


Please make --backup-dir option to store differences in rdiff-backup' style
repository. I.e. not complete copy of backup file, but binary diff (like
xdelta3) of backup version up to the new version. That way backup dirs will be
much smaller if actiual file change of big files is small.

Of course there is still problem of restoring, like in plain --backup-dir, but
that is different question. And that new feature will be good step in advance
of better backups with rsync.

I think this would be overly complex.  The rdiff program can be used for
creating rdiff backups.
