NetBackup for DB2 backup types
Each database agent has a unique set of backup schedules.
Table: DB2 backup types shows the DB2 backup schedules you can specify.
Table: DB2 backup types
Backup type | Description |
|---|
Application Backup
| The Application Backup schedule enables user-controlled NetBackup operations from the client. These operations include those initiated from the client and those initiated by an automatic schedule on the master server. NetBackup uses the Application Backup schedule when the user starts a backup manually. Configure at least one Application Backup schedule for each database policy. The Default-Application-Backup schedule is configured automatically as an Application Backup schedule.
|
Automatic Full Backup
| An Automatic full backup contains a copy of all the data. A full backup is not the same as a whole database backup. Full means that the backup is not one of the incremental backup types.
To perform a stream-based Automatic full backup, also specify an Automatic Full Backup schedule for scheduled NetBackup operations.
Snapshot Client only supports this type of backup and the Block-Level Incremental (BLI) Backup.
|
Automatic Differential incremental backup
| An Automatic Differential incremental backup is an incremental backup that is not cumulative. The backup contains a copy of the database data that has changed since the most recent backup, full or otherwise. This type of backup corresponds to the INCREMENTAL DELTA option of the DB2 BACKUP command.
This type of backup takes less space and time than a cumulative incremental backup. The backup includes only the data that changed since the last backup of any type.
This type of backup is supported only for stream-based backups and for BLI backups.
|
Automatic Cumulative incremental backup
| An Automatic Cumulative incremental backup is an incremental backup that is cumulative. The backup contains a copy of the database data that changed since the most recent full backup. This type of backup corresponds to the INCREMENTAL option of the DB2 BACKUP command.
Automatic Cumulative Incremental backups are supported only for stream-based backups and for BLI backups.
This backup takes less time and space than a full backup; it contains only the data that changed since the last full backup.

For the types of backup schedules, the information in this topic pertains to stream-based backups. If you use the Snapshot Client option, some of the information in that table may differ.
More information about backup schedules and Snapshot Client features is available.
