Humm, thats not too bad, although the $ for the changer would scare this SS recipient off I'm afraid. As would a fifty per disk when the tapelist gets up towards 20 or so. OTOH, with that 36GB capacity, I could do a dumpcycle of 2 days here, so I'd only need 4 or 5. >> Jon (or anyone else with some thoughts here) how would one go >> about dealing with the fact that the Iomega drive is probably a >> random access drive, meaning it would need to use the FILE: >> device, *and* treat it as a robotic changer mechanism to bring the >> proper disk into the drive proper? >> >> The first thing would be to investigate and find out if the mtx >> driver can control the robot. > >Assuming mtx can control the beast, it shouldn't be too difficult to >modify chg-zd-mtx to mount and unmount the media. > >> Without the robotics, and just feeding it the disk cartridge by >> hand, and using the FILE: device, it seems to me that wouldn't be >> too hard to setup assuming that Tom can build snapshot >> 2.4.5b1-20041221.tar.gz, obtainable from the amanda.org front page >> via link near the bottom of the page. > >For those of us who haven't been keeping up with the betas, what's > the must have feature in that one?

I've been using the 2.4.5 stuff almost since it was first added to the snapshot repository with only minor teething pains as I learn about any new features that might be usful to me. Its running so well here, the next step is probably to remove the beta designation. Jean-Louis? >> Whats the rated read/write speeds on that drive Tom?
