It is important to create a backup recovery strategy to protect the databases in Oracle
Database Appliance from data loss due to a physical problem with a disk that causes a
failure of a read from or write to a disk file that is required to run the database, or due
to user error. You can create a backup policy in the Web Console or from the
command-line interface.
The following backup options are available:
•
Backup to an Oracle Fast Recovery Area (FRA) disk (Internal FRA)
•
Backup to Oracle Cloud Infrastructure Object Storage (Oracle Object Storage)
•
Backup to a Network File System (NFS) location (External FRA)
You can use the backup, restore, and recovery features with databases that have
backup policy attached to them in the system. You can choose to manage your
backups, and set up your backup, restore, and recovery option.
The backup feature enables you to create a backup policy with your backup
parameters, including backup level and location. For new and existing databases, you
can create and attach a backup policy to a database to perform a daily backup. Once
a backup policy is attached to a database, the
dcs-agent
schedules daily automatic
backups for the database. The default schedule is a level 0 backup every Sunday and
a level 1 backup Monday through Saturday. You can edit or disable the schedule.
The
dcs-agent
generates and saves a backup report for each backup. The backup
report contains the metadata required to recover or restore a database.
Note:
You cannot backup databases that use Transparent Data Encryption (TDE).
Recovering a database in Oracle Database Appliance is a full or whole database
recovery using RMAN. You can recover from a Backup Report, a point-in-time (PITR),
a System Change Number (SCN), or from the latest backup. For recovery of data
block, tablespaces, data files, PDBs, see the Oracle Database Backup and Recovery
Reference Guide.
Backup Policy
The backup policy defines the backup details. When you create a backup policy, you
define the destination for the database backups, either Internal FRA (Disk) or External
FRA (NFS location), or Cloud Object Storage, and you define the attributes such as
the backup level and the recovery window.
If you use the Oracle Object Storage for backup and recovery, you must have an
ObjectStore Resource ID or Name.
You can assign the backup policy to the database when you create the database. You
can attach a backup policy to an existing database or update a backup policy.
Backup Levels
The backup policy that you create defines the backup level:
•
Level 0: The backup captures all blocks in the datafile. By default, level 0 backups
occur every Sunday. You can customize your backup settings through the Web
