rsync - Mar 2012 - [Bug 8790] New: rsync stream file type

https://bugzilla.samba.org/show_bug.cgi?id=8790

           Summary: rsync stream file type
           Product: rsync
           Version: 3.0.6
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: Dave at Yost.com
         QAContact: rsync-qa at samba.org


Give rsync the ability to write/read its stream to/from an archive file. Almost
certainly the best option would be for rsync to maintain its own archive file
format.

Why do this? Because rsync is awesome, we have learned all of its options by
now, and unlike tar, cpio, etc., rsync captures all metadata, and rsync streams
across a connection.

A future enhancement would be the ability to append an update to the end of the
file.

Another enhancement would be optionally to append an index, so that files could
be retrieved quickly from the archive.

This enhancement could be useful for versioned backups.

Is --write-batch or --only-write-batch what you are looking for?

If it is and you are trying to do backups I suspect you probably want
rdiff-backup instead.  But then you will be back here eventually for
performance reasons.

Yeah, the batch stuff already allows streaming of the protocol, which can batch
up some changes into a single file.  It doesn't allow appending, and really
I
think we should not complicate it further.
