rsync uses TCP, so if the network goes "down" it will detect that.
TCP is a reliable protocol, it has checksums for it's packets so in the
general case no corruption will appear.

Anyway, if you are paranoid you can enable the -c option of rsync in which
case it calculates a checksum of the eligible files, and only transfer
those that its checksums don't match.

In the general case, rsync only compares files based on file-size and
modification time.
