You want to run backups for 6 months with 20 tapes? Tell us more about that, this is not clear to me ...

If you really want to fill your tapes, you could set up vtapes (look into the HOWTO-FILE-DRIVER in the docs) that are nearly as big as your DLTs, and save the vtape-dirs with a second config to your DLTs. I think you should just take the straight way, setup your changer, configure a dumptype for your nearly-static stuff that has a long dumpcycle and start going. If you leave the tapes out, AMANDA will fill your holdingdisk, modify the "reserve"-parameter to even get lev0-dumps in there. -- best regards, Stefan Stefan G. Weichinger mailto:[EMAIL PROTECTED]
