Has anyone developed a backup strategy for this critter? Our Aux 1.0 came supplied on the drive, and we'd like to back it (or 1.1 if and when it...) such that we have a bootable backup...but...if you can't get to unix because it is crashed catastrophically, how in the heck are you goinng to be able to use cpio or tars to get the bloody thing back? What we would like to do is be able to use the Tallgrass tape bup for the mac, as it is a nice inexpensive model that works nicely with the mac os (better than the apple ver., I think...) but no one at apple, tallgrass, etc., seems to have ever thought of backing up Aux before....surely someone has a plan or at least has thought about it!

You can use the Volume Backup/Restore options in many tape backup programs. Some manufacturers currently support backing up and restoring individual SCSI partitions, while others are working on it. The only people who have *really* done it right, apparently, are Irwin Magnetics. I have mixed feelings about their hardware but they're the only people who have actually written a genuine A/UX driver for a tape unit (as far as I know). Alexis Rosen alexis@ccnysci.uucp

A/UX comes with the BSD dump and restore programs. You can use these to back up to any media supported by A/UX (under 1.0 that's floppy and hard disk. 1.1 supports the apple tape unit) or you can back up over the network (assuming you're running an Ethernet or SLIP under 1.1). As for bootable backups, it's true that there is no "mini-unix" (ala BSD Vax or Sun) to boot and run restore, but there is escatology to allow you to repair your root file system sufficiently to run restore. Or, if you feel real lucky, you can just copy another machine's root file system onto your disk, boot, and run restore (don't try that unless you're real sure what your doing). -- Charles. {sun, amdahl, ucbvax, pyramid, uunet}!unisoft!cander
