Introduction

In the upcoming weeks we will be posting new videos to the SAP HANA Academy to show new features and functionality introduced with SAP HANA Support Package Stack (SPS) 11.

What's New with SAP HANA SPS 11 - by the SAP HANA Academy

The topic of this blog is database backup and recovery.

What's New?

Enhancements for SAP HANA Cockpit

Using the SAP HANA Backup tile in the SAP HANA cockpit, you can now not only make full backups, but also delta backups. Delta backups, both incremental and differential were introduced in SAP HANA SPS 10. For more information about delta backups, see SAP HANA SPS 10 What's New: Database Backup and Recovery - by the SAP HANA Academy. To make delta backups in SPS 10, you could only use command line and SAP HANA studio. With SPS 11, this functionality has now been made available for cloud computing in the SAP HANA cockpit.

Resuming an Interrupted Recovery

Recovering a very large database can be time consuming. Having to repeat the whole recovery process because the connection to the recovery tool was temporarily lost, for example, is nobody's definition of fun. As of SPS 11, it is now possible to resume a SAP HANA database recovery.

The way it works, is that during recovery, SAP HANA automatically sets fallback points. The first fallback point is after the backup restore phase when the data files are put back into place. Then at intervals during the recovery phase, that is when HANA is going through the log backups, additional fallback points are set. When there is a failure during this stage, recovery can be resumed. These fallback points are recorded in backup.log.

You can recover a database using SQL statements and the tool (Python script) recoverSys.py.


RECOVER DATABASE UNTIL TIMESTAMP '1999-12-31 23:59:59' USING RESUME



Multistreaming Data Backups with Third-Party Backup Tools

You can now use multiple channels to write the backup data for each service with third-party backup tools. This will make it possible to considerably speed up the backup time by distributing backup data in parallel to multiple devices.

New Certification for Third-Party Backup Tools

In the last months, several new tools have been certified in the BACKINT program, amongst which HP StoreOnce Catalyst Plug-in for SAP HANA.

You can look them up on the SAP Partner Directory with filter "HANA-brint".

For the program, see Backup/recovery API for the SAP HANA database (Backint for SAP HANA (HANA-BRINT 1.1))
