Figure 1–3 Tape Library
Oracle Secure Backup automates the management of tape libraries, thereby enabling
efficient and reliable use of their capabilities. Oracle Secure Backup controls the tape
library robotics so that tapes can be managed easily.
Oracle Secure Backup supports the following features of tape libraries:
■ Automatic loading and unloading of volumes
When you add a tape library to your administrative domain, it is configured in
automount mode by default. In this mode, Oracle Secure Backup sends commands
to the robotic arm of the tape library to mount tapes for backup and restore
operations. When a new volume is needed, Oracle Secure Backup scans the tape
library until it finds a suitable volume. If sufficient eligible tapes are contained in
the tape library storage elements, then no operator intervention is required to load
the volumes needed to store the complete backup image.
■ Barcode readers
A barcode is a symbol code that is physically applied to volumes for identification
purposes. Some tape libraries have an automated barcode reader. Oracle Secure
Backup can use barcodes to identify tapes in a tape library.
■ Automatic tape drive cleaning
Oracle Secure Backup checks for cleaning requirements when a tape is loaded into
or unloaded from a tape drive. If cleaning is required, then Oracle Secure Backup
loads a cleaning cartridge, waits for the cleaning cycle to complete, replaces the
cleaning cartridge in its original storage element, and continues with the requested
load or unload. You can also schedule a cleaning interval.
As shown in Figure 1–3, a tape library has a set of addressable elements, each of which
can contain or move a tape. Libraries can contain the following types of elements:
