You should be able to mount it, depending on your OS, and run "rsync
-avH ---delete [rsnapshotdir] [USBmountdir]/snapshot" to synchronize
the material.

Be sure to use a subdirectory on the USB drive, and avoid taking the
full contents of rsnapshot if the target drive isn't the same
filesystem. Backing up from a Linux style filesystem to NTFS, for
example, witll throw out most of the ownership information and handle
symlinks very differently.
