The following prerequisites need to be in place before any further configuration can occur :
- A VERITAS Netbackup Master server is installed and fully licensed.
- The VERITAS Netbackup Client for RHEL or SLES has been installed on all SAP HANA systems in the landscape. The clients are also fully registered and there are no communication issues between the client and master servers.
- (Optional) A media server is installed and configured with either AdvancedDisk or Media Server Deduplication Pool (MSDP) using NFS shares from a FlashBlade.
- SAP HANA is installed and running on either a Scale Up on or Scale Out instance.
- The Maximum jobs per client value in the Global Attributes of the Netbackup Master server is set to the amount of expected jobs per SAP HANA database.
- Access to the client has been allowed by adding the media server to the Clients Properties under Servers->Media Servers.
Create a Policy for the SAP HANA Backup and Recovery Operations
A single policy can be used for a range of systems or a policy can be created for each individual tenant including the SystemDB.
Under "Netbackup Management" locate "Policies" and under "All Policies" right-click to bring up the context menu and then select "New Policy".
Give the new policy a name and select "Use Policy Configuration Wizard".
Create a backup policy for "File systems, databases, applications".
Select a Policy Type of "SAP".
In the client list, all systems which need to have access to this policy should be added. In a Scale Up landscape this could be individual instances with no relation to one another using the same policy, or systems being used as a part of a storage or system replication group. In a Scale Out landscape all of the nodes must be added to the policy.
If using ActiveCluster and want to incorporate host failover into the failover domain , the second host (Scale Up) or host group(Scale Out) must be added to the client list for the same policy as the first.
Scale Up Landscape:
Scale Out Landscape:
Set the Backup Type to be "Full Backup".
Set the Frequency and Retention Schedules.
Set the schedule windows.
The backup policy has now been created. To set the FlashBlade NFS stores used for AdvancedDisk or MSDP as the storage unit for this policy right click on the policy to bring up the context menu and select "Change".
In this policy, the policy storage has been set to "FB-Dedupe-Pool-stu".
In the Schedules view note the name of the Schedules. SAP HANA will use the default "Default-Application-Backup" unless otherwise specified.
It is important to note that for the storage unit, if parallel data streaming from Backint is going to be used, then the Storage Unit must be capable of and have the Maximum concurrent jobs set to match the parallel value.
Each tenant in a system using multiple database contains (MDC) will use the parallel streams set for the system if the database size is above 128GB. A 4 tenant system set to use 8 streams in the backint configuration will then use 32 streams if all of the tenants are being backed up at once.
