[clug] Deduping backups from more than one workstation?

[Kim Holburn]

There's an option for rsync that does it.  Something like:

rsync  -av --link-dest=DIR  src/dir/ new/dir/

You can make rsync do something very similar to time machine.  Only possibly better - comparing with several directories.  It uses hard links instead of copies.
