The capacity of the HP35470A drive is 2GB and the total capacity of the filesystems I am backing up is less than 2GB, so I don't worry about hitting the end of the tape: dump 0ufB /dev/nrst0 2000000 / dump 0ufB /dev/nrst0 2000000 /usr dump 0ufB /dev/nrst0 2000000 /var dump 0ufB /dev/nrst0 2000000 /www mt -f /dev/nrst0 rewoffl I should subtract the space used from 2000000KB after backing up root, but I'm lazy. This puts the entire system (less /tmp and swap of course) on one tape. This is from a FreeBSD v1.1.5.1 system by the way. With a larger system I would break up the backup sessions to make sure this scheme would not overflow the tape (combining small filesystems) and put any large filesystems onto multiple tapes in additional sessions, keeping tape capacity at 2000000 blocks (or somewhat less) so dump knows when to ask for another tape. | John Lucas jlucas@uvi.edu | | Academic Computing NIC Handle: JL423 | | University of the Virgin Islands (809) 693-1216 | | St. Thomas, VI 00802 http://www.uvi.edu/jlucas.html |
