Incremental Data Backup to a File 
You back up all data that has been saved since the last complete data backup of the database instance.
You can display the status of the backup operation with the DBM command backup_state. When you execute this command, the system displays the progress of the backup.
Scenario
You want to execute an incremental data backup for a file.
You have already executed a complete data backup. You have defined a backup template of type FILE with the name DemoDataInc for the incremental backup.
Prerequisites
You can find the prerequisites under Database Manager CLI, backup_start, backup_state.
Procedure
Call the Database Manager CLI in session mode, log on as operator OLEG with password MONDAY, and connect to the database instance DEMODB:
>dbmcli –u OLEG,MONDAY –d DEMODB
dbmcli on DEMODB>
Open a database session:
dbmcli on DEMODB>db_connect
OK
Start the backup operation using the backup template DemoDataInc:
dbmcli on DEMODB>backup_start DemoDataInc
OK

Result
After you have executed the DBM command, information about the backup is output. This information is only output when the backup has been completed or interrupted. The response to this DBM command can therefore take a long time.
