full or incremental really discribes how they are stored on backuppc. a
full will hang around longer than an incremental. As far as the actual
transfer, the only real difference is that a 'full' doesnt skipp files that
have the same mtime where an incremental skips those files. This causes a
full to hit the CPU on both sides more but it doesnt use very much more
bandwidth as the only added data transfer is the checksum of those files.
