how to use the dds-4
Here's how to use the tape, in a nutshell.
The tape is on helen.cs-i aka dendrite.
Use DDS-2 (8/16 gb) DDS-3 (12/24 gb) or DDS-4 (20/40 gb) tapes.
Automatic bakups happen at night, at or after 1am. So:
* Use the tape only between 9am and 1230 am.
* If there is a tape in the drive, don't forget
to put it back in after you finish.
Use the "tape" (/usr/local/bin/tape) command on helen:
tape status: Info on current tape status
tape rewind: Rewind to BOT
tape eject: Eject cassette
tape fsf N Skip over N recordings
tape feom Goto end of recorded, ready to append at end of tape
tape tar Call tar on tape, example:
tape tar cv . Will dump contents of current directory
tape tar tv . Lists contents of tape
tape tar xv Reads files from tape into current dir on disk
tape write Bulk read/write to/from standard input; example:
tape.write < huge.file Dumps the contents of huge
file to tape
Use tape.read/tape.write to write/read from pipes to
the tape, for example
tar cvf - . | ssh -c blowfish helen.cs-i 'tape.write'
(executes tar on remote machine and writes to Helen's
