Then again, the data is saved decrypted on the destination disk. Maybe
the files should be individually encrypted with a symmetric algorithm on
the source before transmission. This could be done with either a script
or the --source-filter option provided by an experimental rsync patch.
Note that typical encryption algorithms prevent incremental transfer
from identifying unchanged portions of a file; rsyncrypto does not but
I'm not sure I trust its security.
