Backup to External FRA (Network File System)
Specifying a Network File System (NFS) location for backups, enables you to safely
and securely store or retrieve a database backup at any time.
The advantages of using NFS backup location are:
•
With NFS, you can access remote files, locally, by mounting local file systems on a
network.
•
Provides a centralized backup location, without requiring manual refresh.
•
Supports enhanced security options using firewalls and Kerberos.
•
Support for encrypted backups using passwords. You optionally, set the backup
password, and provide the same during restore operation.
The following is a high-level overview of the workflow for backup and recovery when
using an NFS location:
1.
Create a mount point for the NFS location.
The mount point must be accessible from both nodes. The
oracle
user must have
read/write permissions to the NFS location. If the request is being made to a
remote server, ensure that it is running. See Creating a Mount Point for NFS
Backup Location for the procedure to create a mount point.
2.
Create a backup policy specifying the NFS location, and the recovery window for
NFS destination.
3.
Associate the database with this backup policy, either during database creation, or
by updating the backup policy for the database.
4.
Backups are automatically created, and you can also run manual backups. You
can specify manual backup options in the Web Console or using ODACLI
commands.
5.
Manage obsolete backups.
6.
Restore from backup. When you save your backups to NFS, you can restore the
database to the same system or to a different system.
7.
Recover the database from a backup on NFS.
Backup to Oracle Object Storage
Oracle Object Storage is a highly secure, scalable storage platform that enables you to
safely and securely store or retrieve a database backup at any time. Data and the
associated metadata are stored as an object in a logical container (bucket). Oracle
Database Appliance creates a Backup Report and a unique ID to identify each backup.
Oracle Object Storage is tightly integrated with Oracle Cloud Infrastructure Identity and
Access Management. The data, user-defined metadata associated with the data, and
encryption keys are automatically encrypted using 256-bit Advanced Encryption
Standard (AES- 256). The encryption keys are rotated frequently and cannot be
disabled. By default, only authenticated users that have explicitly been granted access
to specific resources can access data stored in Oracle Object Storage. Data is
uploaded and downloaded over SSL endpoints using the HTTPS protocol.
When you backup to Oracle Object Storage, you are using your backup policy and
your Oracle ObjectStoreSwift credentials. The credentials are stored in an encrypted
Oracle wallet. You can attach the credentials to one or more backup policies.
