Oracle Secure Backup Administrative Domain with Multiple Hosts

Tape Devices

Oracle Secure Backup maintains information about each tape library and tape drive so
that you can use them for local and network backup and restore operations. You can
configure tape devices during installation or add a new tape device to an existing
administrative domain. When configuring tape devices, the basic task is to inform
Oracle Secure Backup about the existence of a tape device and then specify which
media server can communicate with this tape device.

This section contains these topics:

Tape Drives

Tape Libraries

Device Names and Attachments

Tape Drives

A tape drive is a tape device that uses precisely controlled motors to wind a tape from
one reel to another. The tape passes a read/write head as it winds. Most magnetic tape
systems use small reels fixed inside a cartridge to protect the tape and make handling
of the tape easier.
