SnapCenter backup operations
You can create an on-demand Snapshot backup and an on-demand block integrity check operation.
Create an on-demand Snapshot backup
Follow these steps to create on-demand Snapshot backups.
In the Resource view, select the resource and double-click the line to switch to the Topology view.
The Resource Topology view provides an overview of all available backups that have been created by using SnapCenter. The top area of this view displays the backup topology showing the backups on the primary storage (local copies) and, if available, on the off-site backup storage (vault copies).
In the top row, select the Back up Now icon to start an on-demand backup.
From the drop-down list, select the backup policy
LocalSnap, and then click Backup to start the on-demand backup.
A log of the previous five jobs is shown in the Activity area at the bottom of the Topology view.
The job details are shown when clicking the job’s activity line in the Activity area. You can open a detailed job log by clicking View Logs
When the backup is finished, a new entry is shown in the topology view. The backup names follow the same naming convention as the Snapshot name defined in the section “Configure and protect a HANA resource”.
You must close and reopen the topology view to see the updated backup list.
In the SAP HANA backup catalog, the SnapCenter backup name is stored as a
Commentfield as well as
External Backup ID (EBID). This is shown in the following figure for the system database and in the next figure for the tenant database PFX.
On the FSx for ONTAP file system, you can list the Snapshot backups by connecting to the console of the SVM.

Create an on-demand block integrity check operation
An on-demand block integrity check operation is executed in the same way as a Snapshot backup job, by selecting the policy BlockIntegrityCheck. When scheduling backups using this policy, SnapCenter creates a standard SAP HANA file backup for the system and tenant databases.
SnapCenter does not display the block integrity check in the same manner as Snapshot copy-based backups. Instead, the summary card shows the number of file-based backups and the status of the previous backup.
The SAP HANA backup catalog shows entries for both the system and the tenant databases. The following figures show the SnapCenter block integrity check in the backup catalog of the system and the tenant database.
A successful block integrity check creates standard SAP HANA data backup files. SnapCenter uses the backup path that has been configured with the HANA database for file-based data backup operations.
