About the types of NetBackup for DB2 BLI backups
NetBackup performs BLI backups with Automatic Full Backup, Automatic Differential Incremental Backup, and Automatic Cumulative Incremental Backup schedules.
NetBackup for DB2 checks that a full backup was performed before it proceeds with an incremental backup. If the NetBackup scheduler or user initiates an incremental backup, and NetBackup for DB2 finds no record of a full backup using the same policy, it performs a full backup.
To ensure that it has a proper set of images to restore, NetBackup performs a full backup when it encounters the following situations:
If the number of backup streams that is specified changed from the previous backup. This change can be made through the GUI or through a DB2 command.
If NetBackup does not have a valid full backup image for the same policy in its database. For example, this situation can occur if images were expired.
NetBackup for DB2 always initiates a full backup under these conditions, even if you want to perform an incremental backup.
