10.12 BACKUP DATABASE

|10.12.1 Syntax Diagram

|The syntax diagram for BACKUP DATABASE will be updated to reflect the new |INCREMENTAL parameter and the optional DELTA argument. Specifying the INCREMENTAL |option alone will result in a cumulative backup image being produced. The |optional DELTA argument can be used to specify the production of a non-cumulative |backup image.

|10.12.2 DB2 Data Links Manager Considerations

|If one or more Data Links servers are configured for the database, the |backup operation will succeed, even if a Data Links server is not available. |When the Data Links server restarts, backup processing will be completed on |that Data Links server before it becomes available to the database again.

|Note:
If there are twice as many backups still waiting for an unavailable |Data Links server as are retained in the history file for the database (database |configuration parameter num_db_backups), the backup operation will fail. |
