I see, I think then that's why there's a separate disk cache option (tapetype:part-cache-type)? So if have a very large DLE and I use disk for cache, it will spool chunks to disk and starting streaming to tape before the whole DLE is written to disk? I want to avoid memory cache since I'd end up with lots of smaller parts (~14GB on my system).
But how do I specify to use disk-cache'ing for level 0, but holding disk for >= level 1 dumps? -M On Thu, Feb 27, 2014 at 5:20 PM, Debra S Baddorf <[email protected]> wrote: > I believe the whole dump has to be done before it starts to write to tape. > This prevents incomplete dumps from wasting space on the tape. > > I try to have numerous smaller DLEs, so that it takes several DLEs to fill > a tape.
