Sorry if this is in the manual set, but I haven't found it yet. We have a Mac with one A/UX disk and one Mac O/S disk connected (these are two separate disks, not partitions) to a network of Suns. What we'd like to do is mount the Mac disk on the network so we can dump its contents to our Exabyte tape drives rather than continue to borrow someone's Apple Tape Drive. Is there a way to do this? Configuration: Mac IIfx running A/UX 2.0 mounted as a yellow pages client on a Sun network running Sun O/S 4.03 and 4.1.1. Thanks in advance, Steve Graham graham@isis.ee.washington.edu

No, but you can consider the following options: 1) Use the MacDump (?) program which is floating around in the MacOS world and which talks to a UNIX host using standard rmt protocols to dump a Mac filesystem. A version of this which works through MacTCP would probably work under A/UX 2.0 and should do proper incremental dumping. Can't say as I've ever tried it though. 2) Use dd under A/UX to save the complete disk image onto the Exabyte. This has the advantage of being much faster than any file-level dumping, but of course you have to pull back the whole thing: you can't get back individual files. The device names to look at are (for SCSI id X) /dev/dsk/cXd0s31 - the complete disk image including MacOS drivers /dev/dsk/cXd0s30 - the HFS volume only The dp program will tell you about the partition sizes, and the block device drivers won't let you run off the end anyway. -- William Roberts ARPA: liam@cs.qmw.ac.uk Queen Mary & Westfield College UUCP: liam@qmw-cs.UUCP Mile End Road AppleLink: UK0087 LONDON, E1 4NS, UK Tel: 071-975 5250 (Fax: 081-980 6533)

Since there are no MacOS programs (that I know of) that do backups using the underlying UNIX facilities you are restricted to ordinary MacOS programs. Hence this question belongs in one of the comp.sys.mac newsgroups ("belongs" just means that you will probably get a better answer there). I know that there are utilities for doing backups over TCP/IP networks. There is at least one free utility for this too. For a pure A/UX solution you can do image backups. If x is the scsi ID of your Mac drive then /dev/rdsk/cxd0s30 contains the image of your HFS partition. You can access it under A/UX as a raw image eg you can do dd if=/dev/rdsk/cxd0s30 | rsh remotemachine ... where ... is the remote backup command you want to use. If you have more than one partition on the dribe you can use pname(1) to access the others. Maybe one day Apple will release UNIX drivers for the HFS filesystem. It won't be an easy job writing the stuff so don't bank on it. Tony Cooper sramtrc@albert.dsir.govt.nz

There is, to my limited knowledge only one MacOS backup program which can also back up A/UX partitions. It works from MacOS (not A/UX), and backs up a full partition at a time. I use Nuvo Lab's ExpressTape to my T150. I use Retrospect for all my Mac stuff, and then ExpressTape to get the A/UX partitions (on a separate tape).
