Dear all, I just want to clarify something about compression:
My understanding is that you can use either software or hardware compression, or can switch between the two if needed. What is generally, in your experience, the best of the two to use? To switch off hardware compression, I believe I should use: mt -f /dev/nst0 compression 0 Does this command switch it off permanently until you use the following?: mt -f /dev/nst0 compression 1 or will hardware compression switch back on, say, after a reboot? I've set up Amanda to use compression as follows, and it seems to work quite well: define dumptype comp-tar { program "GNUTAR" compress fast index yes record yes } But it just dawned on me that I haven't taken into account that our HP SDLT 320 tape drive is probably using hardware compression, so now I'm wondering what's best to do. Thanks in advance. Joe -- View this message in context: http://www.nabble.com/Compression-usage-tf1889370.html#a5165754 Sent from the Amanda - Users forum at Nabble.com.
