I would like to use rdiff-backup to back up sound files (among
others). Some of
the files could be as large as 0.5 GB or more. I am worried about how
rdiff-
backup handles files of this size. I think that performing a diff
would waste
time and disk space.
Hi Jeffrey,
we frequently backup files larger than this all the time. It is
reasonably efficient, as diffs are compressed. Is the audio already
compressed?

Yes, the audio is already compressed. Usually the sound files are
encoded using FLAC.

See this option (from the man page
http://www.nongnu.org/rdiff-backup/rdiff-backup.1.html):
*--no-compression-regexp* *regexp*
Do not compress increments based on files whose filenames match
regexp. The default includes many common audiovisual and ar-
chive files, and may be found in Globals.py.
