>I've read that Quantum recommends a blocksize of 128 bytes for their >DLT-7000 drives, and I would ofcourse like to set this in Amanda. Just a caution. In all my testing I **never** saw performance improve (not enough to make it worth while -- maybe a percent or two). In many cases that you would think would "obviously" make it better, it got worse. So the point is, do a **lot** of testing first before deciding to go down this path. The simplest thing is to just look at your daily Amanda E-mail. It reports the tape write speed. Look at the value for full dumps (since they are large enough to be statistically useful). Is it close to the rated drive speed? If so, then messing with the block size isn't going to make it go any faster. >Klavs Klavsen John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]
