Preparing for SAP HANA application protection

Before you start protecting SAP HANA applications, you must prepare your environment for application data protection. Preparing your environment for SAP HANA application data protection includes the following tasks:

Task	Instructions
Mandatory. Make sure R‑Cloud can access applications that you want to protect.	Enabling access to application data
Optional. Configure SAP HANA application backup options.	Configuring SAP HANA application backup options

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
	R‑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 SAP HANA applications.
	The instance credentials do not have proper permissions and R‑Cloud cannot access applications. To enable R‑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. On the Credentials tab, 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 SAP HANA 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.

Configuring SAP HANA application backup options

Before you start protecting SAP HANA applications, you can adjust application protection to the needs of your data protection environment by configuring backup options.

Backup options

Backup option	Description
Temporary instance configuration	Enables you to specify the region, the zone, and the subnet where you want R‑Cloud to create a temporary instance during the backup. By default, the temporary instance is created in the original project of the application.
Backups	Enables you to configure 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.

Prerequisites

• Only if you plan to configure backup options for multiple applications. All applications must have the same values set for each option that you plan to configure.

• Only if you plan to specify the temporary instance location and subnet. 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 applications for which you want to configure backup options.
2. Click  Configuration. The Application Configuration dialog box opens.

3. Depending on what you want to do, perform the required action:

   I want to...	Instructions
   Specify the temporary instance location and subnet.	On the Temporary instance configuration tab, do the following: From the Region drop-down menu, select the preferred region. From the Zone drop-down menu, select the preferred zone. 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.
   Configure the backup chain length.	On the Backups tab, in the Backup chain length field, specify when you want a new backup chain to be started.

4. Click Save.
