Note that most people probably don't need to worry about this
nowadays.  Disk $/gigabyte just keeps dropping and is now at
absolutely abysmally small levels.  You can only fill up your disks if
you download tons of movies and/or create tons of VMs.

If you're struggling with a laptop drive that's too small, just buy a
new one for $100 and solve all your problems.

So you're fine with storing multiple copies.  Just make sure your
backup/syncing software has an expiration algorithm so you don't end
up storing *all* the historical copies.

I'd like to adapt bup to support this usage model eventually.
However, I haven't yet written the expiration algorithm and it doesn't
yet support two-way syncing.  The fundamental design allows for this,
though, so it's just a matter of having some free time.  Meanwhile,
you might want to take a look at something like rdiff-backup.

Have fun,
