Application Backup

The Application Backup schedule enables user-controlled NetBackup operations from the client. This schedule type allows operations the client initiates and operations an automatic schedule initiates from the NetBackup master server. NetBackup uses the Application Backup schedule when the SAP user starts a backup manually. Configure at least one Application Backup schedule for each SAP policy.

By default, an Application Backup is configured automatically. NetBackup for SAP uses the Application Backup schedule to back up the profile files that are backed up in brbackup phase 2.

Automatic Full Backup

An Automatic Full Backup schedule specifies the dates and times on which NetBackup is to start backups. Backups commence by running the SAP scripts automatically in the order they appear in the file list. If there is more than one client in the SAP policy, NetBackup for SAP runs the SAP scripts on each client. You must configure the Automatic Full Backup schedule in order for Snapshot Client methods to back up Oracle data files.

Automatic Differential incremental backup

In a differential incremental backup, NetBackup for SAP backs up all data blocks that changed since the most recent full or incremental backup. This type of backup can be used with the Snapshot Client BLI method.

Automatic Cumulative incremental backup

In a cumulative incremental backup, NetBackup for SAP backs up all data blocks that changed since the most recent full backup. This type of backup can be used only with the Snapshot Client BLI method or for RMAN stream-based incremental.

Cumulative incremental backups reduce the work that is needed for a restore. You only need one cumulative incremental backup from any particular level at restore time. However, cumulative backups typically require more space and time than differential incremental backups. Cumulative backups duplicate the data that was captured in previous backups at same level.
