I'm backing up numerous large files on another machine on my local

might be able to save some time and space if I incorporate tar and
bzip2. How will rsync interact with those? If I turn the whole
backup into a big tar.bz2, would rsync need to redownload the whole
thing if I change one file? If so, maybe I should turn different
groups of files into tar.bz2 archives so rsync only needs to
redownload an archive if one of its files has changed?
Another way, although a bit more work to setup, whould be to use a "Network
block device". Unlike NFS, the server just exports the block device,
everything else (mkfs, encryption) can be done on the client.

rsync will download only if source and destination files are different.
From my experiences using rar is faster and save more space than bz2.
