...and if this post is still valid, this may be the maximum speed (55M/s) given that the LTO-3 and disk are on the same SD (even though tape compression is on.) http://www.mail-archive.com/bacula-de...@lists.sourceforge.net/msg01246.html [Kern]"...so I forget the formulas for calculating this,

Incompatible? That's not good. I guess I will have to purge the tape and run the copy jobs again. I just set the SD Maximum Block Size to 1 megabyte, and this seems to improved things a lot. During a copy job, when I got a storage status from bconsole it said the rate was 54,008,673 Bytes/sec
