Tape Backup Setup Question
2007-12-25 11:44:00
have not had a chance
to work on this system to try anything. Regardless, here is the summary.
Original question:

> Backing up a system with a few ~3G partitions to an EXB-8500 tape.
Using ufsdump
>with "0cfu" options to /dev/rmt/0mn for one of these partitions
usually ends up with a tape change,
>and only about half the first tape used. Changing to "0bdsfu 126
54000 13000", as was suggested
>to me, yields the same results. If I'm correct, I should be able to
dump about 5G to an
>8mm tape on an EXB-8500, correct?

>Any hints/pointers to correct this is greatly appreciated. I have
looked at man st and man

The main suggestions, in order, were:
1. Remove the s and d parameters and let the system do it's own end
of tape detection.
2. Have the tape drive checked for proper operation
Thanks, all. I'll give these a try in order, as soon as They quit
throwing fires at me. :-)
