Overview of Protected Database Recovery Settings

Table 3-3 describes the recovery settings for protected databases. The values of some settings (for example, fast recovery area), are assigned based on how the protected database is configured for the Recovery Appliance.

Table 3-3 Protected Database Recovery Settings

Recovery Setting Description

Recovery Setting	Description
Desired mean time to recover	The Mean Time to Recover (MTTR) is the time required to recover the protected database. Plan your backup strategy based on an MTTR that is acceptable for your protected database.
`ARCHIVELOG` mode	The `ARCHIVELOG` mode enables archiving of filled groups of online redo log files immediately after a redo log switch occurs. Optionally, configure the following additional properties for the protected database: Log Archive File Name Format Specifies the default file name format for archived redo log files. Use a text string and variables to specify this value. Valid variables are described in Oracle Database Reference. Archived Redo Log Destination To use the fast recovery area as the redo log destination, set the Archived Redo Log Destination to `USE_DB_RECOVERY_FILE_DEST`. Note: Running the protected database in `ARCHIVELOG` mode is mandatory if you want to send redo data to the Recovery Appliance. See Also: Oracle Database Administrator's Guide for information about configuring your database to run in `ARCHIVELOG` mode.
Fast recovery area	A fast recovery area is a disk location that stores backup-related files such as RMAN backups, archived redo log files, control file and online redo log file copies. The fast recovery area automates management of backup-related files and minimizes the need to manually manage disk space for backup-related files. See Also: Oracle Database Backup and Recovery User's Guide for more information about configuring a fast recovery area.
