Try this: # /sbin/dump 0uBbf 1200000 10 /dev/nrst0 /[path] * B = number of records per volume * b = number of kilobytes per dump record The above command allows me to dump all 6 partitions, about 500meg. I too was curious as to just how many records fit on a 295 foot/ 90M tape. Is this a fixed number? Specifying the BPI & total feet on the tape won't work.
