One thing that helps is to break it up into separate runs, at least
per-filesystem and perhaps some of the larger subdirectories.
Depending on the circumstances, you might be able to do an initial run
ahead of time when speed doesn't matter so much, then just before the
cutover shut down the services that will be changing files and
databases and do a final rsync which will go much faster.

Also, have you looked at clonezilla and ReaR?
