Preparing for SAP HANA application protection

Before you start protecting SAP HANA applications, perform the following tasks:

Task	Instructions
Mandatory. Make sure HYCU for Google Cloud can access applications that you want to protect.	“Enabling access to application data”
Optional. Specify the location and the subnet for the temporary instance that HYCU for Google Cloud creates during the backup.	“Specifying the temporary instance location and subnet”
Optional. Configure the backup chain length.	“Configuring the backup chain length”

Enabling access to application data

After you assign credentials to instances as described in “Enabling access to data”, the process of application discovery starts automatically. When the application discovery task completes, the discovered applications are listed in the Applications panel.

Each discovered application has one of the following statuses:

Discovery status	Description
	HYCU for Google Cloud can access discovered applications that you want to protect with instance credentials. However, if your applications require database-level authentication, you must make sure to provide also application-specific credentials before you can start protecting your data. In this case, follow the procedure described in this topic. Otherwise, you can continue with protecting application data as described in “Backing up applications”.
	The instance credentials do not have proper permissions and HYCU for Google Cloud cannot access applications. To enable HYCU for Google Cloud to access the applications, reassign credentials to instances so that they have proper permissions. For instructions on how to assign credentials to an instance, see “Enabling access to data”. After the discovery status of your application is , make sure to provide also application-specific credentials if your application requires database-level authentication. In this case, follow the procedure described in this topic.

Procedure

1. In the Applications panel, select the applications that you want to back up.

2. Click  Configuration. The Application Configuration dialog box opens.

3. In the Credentials section, make sure the Use instance credentials switch is disabled, and then enter credentials for a user account with required permissions and access to the applications.

4. Click Save.

You can continue with protecting application data as described in “Backing up applications”.

You can later unassign the credentials from an instance or delete the instance credentials that you do not need anymore. For details, see “Enabling access to data”. Keep in mind that you can do this only if the discovered applications running on the instance do not have assigned policies or available restore points. Therefore, before unassigning or deleting credentials, make sure to unassign policies or mark restore points as expired.

Specifying the temporary instance location and subnet

You can specify the region, the zone, and the subnet where you want HYCU for Google Cloud to create a temporary instance during the backup. By default, the temporary instance is created in the original project of the application.

Prerequisite

VPC Network Peering must be configured. For details on how to configure VPC Network Peering, see Google Cloud documentation.

Procedure

1. In the Applications panel, select the application for which you want to select the temporary instance location.
2. Click  Configuration. The Application Configuration dialog box opens.

3. In the Temporary Instance Configuration section, specify the region, the zone, and the subnet:

   1. From the Region drop-down menu, select the preferred region.
   2. From the Zone drop-down menu, select the preferred zone.

   3. From the Subnet drop-down menu, select the preferred subnet. By default, the temporary instance is created in the default subnet of the preferred region and zone.

4. Click Save.

Configuring the backup chain length

You can adjust application protection to the needs of your data protection environment by configuring the backup chain length. In this case, a new backup chain is started when the number of the full and subsequent incremental backups in a backup chain exceeds the value you specify. The default value is 7.

Procedure

1. In the Applications panel, select the application for which you want to configure the backup chain length.
2. Click  Configuration. The Application Configuration dialog box opens.
3. In the Backups section, specify when you want a new backup chain to be started.
4. Click Save.
