Oracle Secure Backup
Oracle began bundling its own Secure Backup solution with Oracle Database 10g.
Called Oracle Secure Backup Express (XE), it replaced Legato??™s Single Server Version
(LSSV) tape storage management. Since Enterprise Manager 10g Release 2,
Secure Backup is integrated into the Enterprise Manager interface. Secure Backup XE
leverages RMAN??™s reading the database block layout directly and provides tape data
protection for one server attached to one tape drive. Where an enterprise solution is
needed, Oracle offers an optional Secure Backup version that can support multiple
drives for any number of servers.
Making Sure the Backup Works
The key to providing an adequate backup and recovery strategy is to simulate recovery
from failure using the backups from your test system before using the backups to
restore a live production database. Many times, backup media that were thought to be
reliable prove not to be, or backup frequencies that were thought to be adequate prove
to be too infrequent to allow for timely recoveries.
