Well, IIRC, DDS2 drives from HP spec 500KB/sec (30MB/min, 1.8GB/hr). Tapetype will have to write 4BG, rewind, write 4GB. You do the math. > My question: Should I have used the compression device (/dev/rmt/0mbn or > /dev/rmt/0hbn) instead of the non-compression device?

Somewhere in the tapetype docs it must say DO NOT USE HARDWARE COMPRESSION! BTW on Solaris at least, /dev/rmt/0 (with no l,m,h,...) means use the default density, not the lowest or no-compression density. In my case, an HP DDS3 drive, the default 0 is the same as 0c, i.e. compression. BTW it will not affect tapetype, but the "b" devices are not recommended for use with amanda. -- Jon H.
