[rdiff-backup-users] Backing up sound files

[Jeffrey Barish]

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.  I think that it would be more useful if I could tell 
rdiff-backup simply to check the modified time and the size when deciding 
whether to update the mirror and to not store a diff.  Is this possible with 
rdiff-backup?  Am I fantasizing a problem?  Is there a tool that might be 
better suited for what I am trying to do?
