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 reading-list in 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 Amanda backup 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.
