9.2.4. Backing up data using a tape device
This is done using tar (see above). The
mt tool is used for controlling the magnetic
tape device, like /dev/st0. Entire books
have been written about tape backup, therefore, refer to our
Appendix B for more
information. Keep in mind that databases might need other backup
procedures because of their architecture.
The appropriate backup commands are usually put in one of the
cron directories in order to have them executed on a
regular basis. In larger environments, the freely available
suite or a commercial solution may be implemented to back up
multiple machines. Working with tapes, however, is a system
administration task beyond the scope of this document.
