Conventional RMAN Backup and Recovery

You can migrate data to Exadata Cloud at Customer by using Oracle Recovery Manager (RMAN). RMAN facilitates a physical migration approach, which is favored in migration scenarios where physical database re-organization is not necessary.

RMAN is an Oracle Database client that performs backup and recovery tasks on Oracle databases. You can use RMAN to migrate data to Exadata Cloud at Customer simply by transferring a backup of your source database to Exadata Cloud at Customer and restoring it there. You can also restore from backups stored in Oracle Database Backup Cloud Service.

If your source database resides on Linux x86–64 (like Exadata Cloud at Customer), and it uses Oracle Database 11g Release 2, or later, you can use RMAN to restore a backup of your source database on Exadata Cloud at Customer.

If you use conventional RMAN backup and recovery to create a database on Exadata Cloud at Customer, note that it is not automatically registered with the Exadata Cloud at Customer console and cannot use cloud tooling for database administration. To enable the Exadata Cloud at Customer console and cloud tooling, see Registering a Database.

RMAN also provides an active database duplication feature, which performs duplication over a network link between the source and target databases. You must consider the size of your source database, and the speed and reliability of your network connection to determine the feasibility of this approach.

For information about using RMAN, see Oracle Database Backup and Recovery User's Guide for Release 18, 12.2, 12.1, or 11.2.

Note:

RMAN provides other options if your source database platform differs from Exadata Cloud at Customer:

  • If your source database resides on another little-endian platform, you can use RMAN to transport the entire database to Exadata Cloud at Customer. See Transportable Database.

  • If your source database resides on a big-endian platform, then you can only use RMAN along with the Transportable Tablespaces feature of Oracle Database. This option can only be used to migrate your data tablespaces, not administrative tablespaces, such as SYSTEM and SYSAUX. See Transportable Tablespaces.
