amanda-users, amanda-hackers, Is support for simultaneously writing to multiple tape drives on the Amanda roadmap? If so, when can this be reasonably expected? If not, what are the major complexities prohibiting this development and is there anything that is required in order to raise its priority?
My situation is that I manage an Amanda system that uses an MSL4048 dual-drive (LTO-4) library. The system is well tuned, writing as fast as can be expected to a single drive for the duration of the backup run. Obviously I could split my Amanda configuration which I may soon have to do, but I would like to know where Amanda is heading in the medium-term regarding this issue. I may eventually need to upgrade to a quad-drive system (or switch technology) to obtain the transfer rate required to archive some of our huge bioinformatics volumes in the available time window. And as an aside, would anybody please care to comment about their experience of running a split configuration on a single backup host using a single changer library. For example, does chg-zd-mtx play nicely with multiple accessors, or are there other, non-obvious problems that make this a bad idea. Many thanks, Terry
