I want to use rsync to backup a large file (say 1G) that changes a little each day (say 1M), but I also want the ability to re-create older versions of this file. I could use --backup, but that would create a 1G file each day, even though I only "really" need the 1M that's changed. How do I tell rsync: "while updating, also store the changes you'd need to convert today's backup into yesterday's backup"? I realize I could use diff or something, but since rsync has to calculate minimal changes anyway, it'd be nice to store them. I thought the --itemize-changes option might do this, but no. -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.
