SAP differential backup
yesterday I configured the backup of our Oracle based SAP servers (ERP6) using the SAP agent with backint (no RMAN).
I followed the instructions of the "NetBackup for SAP Administrator's Guide" and generally it is working, now.
I used the script "sap_online_backup" as a base and customized it to fit our environment.
Then I created a policy with the following schedules:
Unfortunately the schedule "Differential-Inc" (additional to the archive logs) always backs up the whole database.
Therefore every differential backup has a size of about 100 GB, though only a few MBs were changed since the last backup.
Is this a known problem?
Did I forget something during configuration or do I need to change anything within the backup script?
Thanks for your help,
