Enable checksum-caching, modify IncrLevels so that you don't re-transfer
more and more data during each incremental.

Also, I frequently add bwlimit to rsync so it doesn't 'flood' the remote
link during backups. This can allow me to do some backups during periods
which would otherwise not be possible (ie, business hours).

Adam
