We have an Exabyte 8mm tape drive hooked up to our Sun 3/60 running 4.0. This tape drive lets you use the 8mm video tapes for backups -- 2 gigabytes per tape. Our largest filesystem is currently 500MB so I want to put two or more filesystems on one tape. Typing dump 0uncsf 50000 /dev/nrst9 /dev/sd0a dump 0uncsf 50000 /dev/nrst9 /dev/sd0h will copy two filesystems OK but I can only get restore to read the first one on the tape. The "s" option doesn't seem to skip like I want it to. So what am I doing wrong? Eric (P.S.: I'm using a length of 50000 because it's a ridiculous length that should more than exceed what I actually need... I have basically no docs on this Exabyte drive so it's been pretty much all guesswork on my part up to now...) Eric Giguere giguere@csg.UWaterloo.CA

I use a dump like the following as a cron job Monday-Thursday /etc/dump 0fubsd /dev/nrst1 50 6000 54000 /dev/rid000a /etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000e /etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000f /etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000g /etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000h /etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid001e If I to restore something, usually off /dev/rid000h which is our /home partition, I use the restore as follows. restore ibfs 50 /dev/nrst1 5 Hope that helps.
