Re: trying to use dump for backup.....

[Alex Vorobiev <sasha forum swarthmore edu>]

i've got an RH 5.1, HP SureStore, diff. capacity...  

had the same problem. 
someone a couple of years back suggested specifying tape capacity in 
blocks explicitly instead of relying on the densityXlength calculation
by dump.  so, my dump command looks something like this (for a 120m tape, 
assuming that its default capacity, i.e. uncompressed, is 4 gig):

dump 0uBf 4000000 /dev/nst0 FILESYSTEM
