To make the initial dump of your /usr partition to a 150 MB QIC tape: dump 0uBf 150000 /dev/rst0 /usr to make the first incremental dump the next day dump 8uBf 150000 /dev/rst0 /usr to make the next incremental dump the other day dump 9uBf 150000 /dev/rst0 /usr where this dump was just the diff to the previous day, so you would require all three tapes to do a full restore. Alternatively, you could dump with level 8 (or less) the third day, thus eliminating the tape from the second day (only the level 0 tape plus the third day level 8 tape were needed for a full restore). As a rule of thumb: the lower the dump level, the more will be on the tapes. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
