I have a group of people using various kinds of pc's. I need on occasion to be able to back up - and let them back up - their machines to tape. I dont want to buy 25 tape drives. The machines are all on an ethernet but we dont run novell... Anyone know of a setup where everyone can have a controller and we pass the tape drive around? Or does anyone have any other sugestions? Thanks Larry Fischer

I use a Colorado Memory 60MB drive to backup network machines via ethernet/TOPS. This works fine, except the archive bits on the clients are not reset. (Not a problem for me) You can go that route, or buy one drive (about $300), an "External Kit" (about $150), and an adapter for each machine (about $100). So your cost to have the clients do local backup is $300+$150+($100 X #machines). Theoretically, you don't need the adapter board; the CMS drive will run off the floppy controller. But that's for internal mounting -- if you want to drag the drive around you'll want the adapter for its connector if nothing else. (Unless you like opening the machines a lot?) You didn't specify the network you're running, but if it's TOPS then the obvious cost-sensitive solution is to get the CMS drive and backup over the ether. CMS might work with other networks also; the tech guy I talked to didn't know anything about backing up over a non-novell network, but no gyrations were needed for TOPS. (CMS's driver program says "Backing up non- DOS drive", but it backs it up anyway...) The tapes for the CMS drive hold 60MB, but with compression on claims are made for 120MB - 150 MB per tape. I'd say 100MB/tape is probably a solid prediction overall. A single backup set can span 99 tapes, according to the manual. Lots of people sell CMS: Look in the Shopper. ----------------------------------------------------- Gordon S. Hlavenka cgordon@vpnet.chi.il.us Disclaimer: Yeah, I said it. So what?

We have done this in the past, but I've found that my users a much more judicious about using backups if they don't have to go get the drive and hook it up to their machines. I buy internal drivers for all new systems and they get a LOT more use. Every week! >Theoretically, you don't need the adapter board; the CMS drive will run off >the floppy controller.

Sounds like a lot of hassle. I seem to remember that the old XTs had an external floppy connector on the controller card. I think this is where these kind of drives became popular. -- Marshall L.

Internal drive = $249 External kit + adaptor board = $100 total = $349/drive Plus, $75/board for each client if you want local backup. These prices are for Hard Drives International - see any PC related magazine. -- ___Mark S.
