Having just started to use a Compaq 386 with SCO Xenix, I find myself in a state of requiring some decent backups. My disk is 300 Meg, with two file systems on it. I don't want any piddly 60 Meg tape drive units. I would like to get something on the order of 300 Meg, if not higher. Anyone have any of these beasts? If so, which ones (and who supplies the driver?). Also, I'll be adding additional machines of the same configuration and will be networking them via Ethernet. It would be nice to have *one* backup device to do all of the work. Thanks. milan@gpu

Your only other alternative is to get a mag tape drive.

The January 17, 1989 (volume 8, number 1) issue of PC magazine has a review of the only (I think) two 2 GIGABYTE backup devices available. The only one that provides drivers for XENIX is the VAST device from Emerald. The other, POWERstreamer IV from Performance Technology Development, only has software for DOS and PC networks. Both devices are based on the Exabyte EXB-8200 tape drive, using 8mm tape and helical-scan technology. The VAST device, according to the review, is slower due to the 8-bit SCSI controller it uses, but still faster than most of the 1/4 inch vertical-scan technology systems available. Barring the VAST device, your best bet seems to be 150MB 1/4-inch devices. There's a significant difference in cost, but look at the differences in speed and storage capacity! To back up several systems on a network using 150MB tapes, figure 4 tapes and user time on a daily basis. With one of the helical-scan devices, on tape could last several days and backups could be entirely automated! I recommend reading the reviews in PC Magazine. -- : Steven List @ Transact Software, Inc. : {apple,coherent,limbo,mips,pyramid,ubvax}!mrspoc!itkin : Voice: (415) 961-6112
