Yes, when using rsync as the xfer method, 'full' backups do the block 
checksum comparison on everything while 'incremental' runs skip files 
where the timestamp and length match the base copy (normally the last 
full but you can adjust it to include other incrementals in the 
comparison base).

Yes, that is one of the choices and probably the best.

It normally checks once an hour for any computers where the time between 
backups has elapsed so the scheduling will accommodate unavailable 
targets.  It doesn't have a concept of it's archive directory being 
gone, though.  You'll probably have to start and stop the service when 
you connect/remove it.
