I recently deployed an HP changer with SDLT320 drives. Like you, I couldn't find any canned tapetypes or other information. I scaled up an existing SDLT220 tapetype, and so far that has worked fine, but I'm nowhere near filling up a tape, so I'm not confident I got it right. ;) define tapetype COMPAQ-SDLT320 { comment "StorageWorks MSL5026S2 library" length 163010 mbytes # educated guess filemark 736 kbytes # ditto speed 15360 kbytes # this isn't really used } I also shamelessly ripped off an idea that someone posted here with regard to ensuring HW compression is turned off. Since you are also planning to run Linux, this should work for you. in /etc/modules.conf: post-install st mt datcompression off This instructs the kernel to run the command 'mt datcompression off' after loading the st driver. That should ensure that HW compression is turned off even after resetting the drive and/or rebooting the host. As for your question 3), I like to use software compression since I have fairly fast clients, and it helps AMANDA make better estimates of how much tape will be used. Cheers, Eric
