Planning

Review planning information for backup strategies, storage requirements, network considerations, and performance optimization.

Planning your backup strategy
To avoid data loss from SAP HANA databases, you must run full backups and redo log file backups regularly.
Optimizing Data Protection for SAP HANA performance
When SAP HANA backs up data, it sends data for all SAP HANA services, such as nameserver and indexserver in parallel from all nodes. If data is intended to go directly to tape, the number of allowed mount points for the IBM Storage Protect™ node must be adjusted.
Optimizing data transfer performance
When you use Data Protection for SAP, data is passed from disk through to the network and finally to tape. A balanced configuration can help to prevent bottlenecks and to ensure optimized performance.
Optimizing network performance
When you are setting up the network, there are some items to consider that can improve network performance.
Optimizing backup server resources
Data Protection for SAP uses the IBM Storage Protect™ archive function for all backup activities. When you are setting up the IBM Storage Protect™ server for use with IBM Storage Protect™ for Enterprise Resource Planning, the following considerations help you to optimize performance when you set up the IBM Storage Protect™ server.
Planning storage space for SAP HANA backups
Before Data Protection for SAP HANA sends data to IBM Storage Protect™, it notifies the IBM Storage Protect™ server of the amount of data that is going to be sent. This enables the IBM Storage Protect™ server to select the appropriate storage pool that accommodates this specific amount of data.
Planning Parallel backup paths and backup servers
Data Protection for SAP can use several communication links between IBM Storage Protect™ clients to control alternative backup paths and alternative backup servers. This feature can increase throughput by transferring data over multiple paths simultaneously or to and from several servers in parallel. It can improve the availability of the IBM Storage Protect™ client to server communication and enable disaster recovery backup to a remote IBM Storage Protect™ server.
Archiving inactive data
Data Protection for SAP creates a database image that is stored at the bit-level and can be used for routine backup operations.
Backup and restore performance considerations
Configuration changes and infrastructure problems affect backup and restore operations.
Creating multiple redo log copies
Data Protection for SAP can save a number of copies of each redo log by using different IBM Storage Protect™ server management classes. By creating multiple redo-log copies on separate physical media, the administrator can restore and recover a database even if a backup tape becomes corrupted.
Creating a user with limited permissions
The profile parameter HDB_KEYSTORE_ENTRY specifies the name of a key in the user store. The credentials of the named key are used to connect to the HANA database. IBM Storage Protect™ for Enterprise Resource Planning: Data Protection for SAP HANA uses this key to gather details about the database size, and the status of backup from the SAP HANA database.
