Will the Fastpath be good enough to do the dumping or do I need a direct Ethernet connection? What is your set up? I would like to get this working here. From: efwjr@triton.paradyne.com (Ellsworth Warmouth (813)530-2882) Path: triton!efwjr Some other questions: Have you ever had a disk fail? Can you do a full restore after replacing the hard-drive or do you have to have most of the system software in place? Do you do incremental backups or a full image every night? Any other suggestions for getting macdump working smoothly? Thanks >----- >Randy Thomas Voice: (404) 631-2246 >Americas Field Technical Support Pager: 800-SKY-PAGE id #27606 >Cray Research, Inc.

CAP is the Columbia AppleTalk Protocols; a set of libraries that allows most *nix boxes to speak AppleTalk. Look on cunix.cc.columbia.edu; there is also a rutgers version that fixes some bugs. Look on rutgers.rutgers.edu for ru-cap.tar.Z. There is a lot of black magic (and other colors, too :-) in getting it to work; don't ask me what I did, I'm sworn to secrecy - well, okay, I'm not sure why what I did worked. Seems to be a common occurrence in Tech Support :-) Yes, I've dropped (well, the user did) a disk. Made a mess on the floor. I replaced the drive with a spare, went to another mac, daisy-chained the disks together, and ran the restore program to suck the disk back down from the Sun. The user was happy, I was happy, the local KFPS-4 breathed a sigh of relief when the traffic stopped. I do full dumps once a week, incrementals nightly. The entire Sun filesystem where the Mac dumps are stored gets a full backup weekly, incrementals nightly; it's all timed so the Macs dump and then the Sun dumps. I had to bash on the Unix sources for macdump and macdumpmgr to get them to put things where I wanted, and log the messages I wanted logged. Mostly tinkering; the guts of the backup code were left unchanged. ----- Randy Thomas Voice: (404) 631-2246 Americas Field Technical Support Pager: 800-SKY-PAGE id #27606 Cray Research, Inc.

I just hooked a Sun boot box with a approx 600MB WREN-VI and a 60MB archive tape and tried running Fastback II and it was able to see and use the tape drive. I didn't get any "extra" driver. Since the Exabyte is seen on the SCSI bus as a tape device, I'd expect this to work as well. (When I get a chance, I'll try it and let you know. We just put an Exabyte on a Sun SLC workstation, and it`s protable so I can just hook it up and try it out.) -Carl PS. Does anyone know what is a good tape-reading/writing program for the Mac? I'd like to maybe write TAR format tapes and read/write them on the same portable tape drive... thus I can backup my Mac, and also move very LARGE amounts of data between my Sun/Unix system and my Mac. -- Carl A Baltrunas 408/922-6206|SMTP:carl@doctor.TYMNET.COM,carl@tymix.tymnet.com BT Tymnet (Network Services) |UUCP: ...!{ames,pyramid}!oliveb!tymix!doctor!carl PO Box 49019, MS/C41 |PDP-10 support: 36-bits forever! well, awhile!
