Re: tape pools, wrapping my mind around them
You want 3 storage A vtape can only contains backup from one storage. You use the storage 'dump_selection' and the dumptype 'tag' to specify which dle go to that storage You could use a different pool for each storage. But using the same pool for all storage have a big benefits: - no need to allocate a specific range of slot for each storage sales use vtape-001, after a few days it is no longer needed (from the policy), then research or support could use vtape-001 Jean-Louis Le jeu. 15 nov. 2018, à 15 h 30, Jon LaBadie a écrit : > I currently have 240 Vtapes in a single changer. > Suppose I have 3 "departments", sales, research, > and support. > > Could I create 3 dumptype definitions so that > all "sales" DLEs are backed up to a tape pool > consisting of vtapes 1-80, "research" to vtapes > 81-160, and "support" to vtapes 161-240? > > If so, then a single config could handle keeping > the various data separated while still maintaining > balance etc. Of course, is the balance on a tape > pool basis or on a total configuration basis? > > Jon > -- > Jon H.

RE: tape pools, wrapping my mind around them
I believe that you would define tape pool of 80 for each, with regular expressions you may be able to have the same label string format but different tape number ranges. Maybe like this? Sales POOL1[0-9][0-9] Support POOL2[0-9][0-9] Research POOL3[0-9][0-9] For sanity I think I'd define 3 tape pools in the one changer. You spend time loading and unloading tapes to find the pool and tapes you want, but since this is done without having to access a physical tape drive or robot it will take virtually no time at all. -Original Message- From: owner-amanda-us...@amanda.org On Behalf Of Jon LaBadie Sent: Thursday, November 15, 2018 3:25 PM To: amanda-users@amanda.org Subject: tape pools, wrapping my mind around them ATTENTION: This email came from an external source.
