Backups

Your Company’s Take on Backups

Backup and recovery for a SAP instance is best handled along with the other
backup and recovery needs of your company’s computer systems. But for those company’s who do not yet possess a solid backup and recovery solution, or who simply want to segragate the SAP landscape from all other internal IT solutions, here are a few things you need to know.

Online versus offline, high availability, frequency, are all decisions your IT staff need to make based on their history with similar procedures at your company, the recommendations of SAP, and the guidance of your implementation Basis consultant. Enforced backups, and detailed and tested recovery procedures should be part of any Disaster Recovery plan, and a documented part of any SAP implementation project.

If your company falls into the latter category, SAP does supply tools for your uses which can be used in either line command form or from within the SAP instance. If you SAP server contains a tape drive or has access to the network tape unit, transaction DB13 can be used to schedule periodic backups. This is the same transaction where weekly statistics, log cleanup, and database verification jobs are scheduled in the post-installation work after installation of a new SAP instance. DB13 scheduled BRCONNECT runs which can also be CRONed in command line form by the IT staff.

For more information, please see the SAP Online Documentation for DB13 by going to the DB13 transaction and clicking Help -> Application Help or referring to the section Creating Database Statistics, Index Rebuilds, and Log Backup Jobs – Oracle. More information regarding BRCONNECT can be found in the SAP BRCONNECT Guide which can be found at http://service.sap.com/instguides.
