Subject: Re: Why diskdirs pools
The main benefit that I see is that you can backup more clients simultaneously
than you have tape drives in your library.
For example, if you want to backup 10 clients at the same time and only have 4
tape drives 6 of the clients will just sit there waiting for tape mounts. If
they backup up to a disk pool first then you don't have this problem.
