backup to 150-MB cartridge tape

[Patrick Goebel]

This is in reponse to Danielle's question about backing up to 150-MB tapes
instead of the 60-MB ones.  These are the parameters I was told to use by
our Sun FE:

/usr/etc/dump [0-9]uctsdf 18 620 1250 /dev/nrst0 /dev/rsd6[a-h]

where the named devices are obviously specific to your system and the tape
length (in this case 620') might vary according to manufacturer.  Using
these parameters, dump issues reasonable estimates of needed tape capacity
for a given file system, assuming the full tape capacity is 150 MB.
