The other xfer methods transfer everything, but rsync should only
transfer changes from your last full run.

Full rsync runs should do block-checksum compares of all files which may
take a long time but should not take a lot of bandwidth. Incremental
runs will be faster because they only transfer the differences in files
where the timestamp or lengths have changed.

It should be doing what you want now. You just need to balance the full
vs. incremental runs for the tradeoff you want in runtime vs. rebuilding
the tree for the next comparison.
