Follow-up Comment #1:

Hi Guru,

rdiff-backup uses the Rsync algorithm for comparing files, not hashing.

The unstable version of rdiff-backup has a feature to calculate sha1 hashes,
but those are only used as a consistency check during the restore operation
(not to check if a file has changed).

A metadata file that large probably contains .... a lot of metadata. If you
are on a Mac, this would be all of the resource forks as well (thumbnails for
each file).

You can open the metadata file to see what it is full of -- it is simply a
gzip compressed text file.

As a backup program, I do not think "speed improvements at the cost of
integrity" ever makes sense. If that is what you need, then perhaps
rdiff-backup is not for you. rdiff-backup tries very, very hard to maintain
absolute integrity of the mirror.


Since this is not a bug, I am closing the report. If you want to add a
feature request, please put it on the Wiki: http://wiki.rdiff-backup.org


Thanks,
Andrew
