Hello

we use the spooling feature and run all *jobs* concurrently. With this  
you get adjustable sized "blocks" written to tape sequential to  
maximize throughput and concurrent spooling for all other jobs. Works  
trouble free but you need a really fast spool device for anything  
faster than LTO-3.
