Best Practices: RDA with NetVault Backup and vRanger and the DR Series System

This topic introduces some recommended best practices for using DR Rapid operations with the DR Series system.

RDS and non-RDS type containers can exist on the same DR Series system
The DR Series system supports having both RDS and non-RDS containers on the same appliance. However, this can cause incorrect capacity reporting as both container types share the same underlying storage.
RDS replication and non-RDS replication on the same DR Series system
Non-RDS replication must be configured, and it is replicated on a per-container basis. However, this type of replication will not replicate RDS containers. RDS replication is file-based and is triggered by the DMA.
Do not change the container connection type from NFS/CIFS to RDS
A non-RDS container must be deleted before this container can then be created as an RDS container using the same name.

Setting client-side optimization

Client-side optimization (also known as client-side deduplication) is a process that can contribute to saving time performing backup operations and reducing the data transfer overhead on the network.

To configure dedupe/passthrough before the client makes a connection, you need to use the DR Series system command line interface (CLI).

* 
NOTE: To update a client in the DR Series system GUI, the client must already be attached (and therefore enabled to appear in the GUI). If a client connection exists, you can select the radio button in the GUI to modify it.

You can turn client-side optimization On or Off by using the CLI commands, rda --update_client --name --mode. For more information about DR Series system CLI commands, see the DR Series System Command Line Reference Guide.

Adding RDS devices in NetVault Backup

To add RDS devices in NetVault Backup:

1.
Start the NetVault Web user interface (UI), and log on to the NetVault Backup Server.
2.
Start the configuration wizard by doing one of the following:
◦
In the Navigation pane, click Guided Configuration, and then, on the NetVault Configuration Wizard page, click Add Storage Devices.
◦
Alternatively, in the navigation pane, click Manage Devices, and then click Add Device.
3.
Select the RDA Device option, and click Next.
The Add RDA Device page is displayed.
4.
In Host, enter the IP address or the system host name of the DR Series system.
5.
In Username, enter backup_user.
* 
NOTE: The Username, backup_user is case-sensitive. You can configure RDS containers only while logged on the DR Series system with username backup_user.
6.
In Password, enter the password used to access the DR Series system.
7.
In LSU, enter the name of the RDS container.
* 
NOTE: The RDS container name in LSU is case-sensitive. Ensure that you enter the RDS container name exactly as it is on the DR Series system.
8.
In Block size, enter the block size for data transfers. The block size is specified in bytes. The default block size is 131,072 bytes.
9.
If the device is already added to another NetVault Backup Server with the same name, select the Force add check box. This option can be useful if you have performed a disaster recovery to rebuild the NetVault Backup Server.
10.
Click Next to add the device.
After the device is successfully added and initialized, a message is displayed.

Removing RDS Devices From NetVault Backup

Refer to the following steps to remove existing RDS devices from NetVault Backup.

* 
NOTE: Removing an RDS device from NetVault Backup does not delete the data stored in the RDS container on the DR Series system.
1.
Start the NetVault Web user interface (UI), and in the Navigation pane, click Manage Devices.
2.
In the list of devices, locate the device, and click the corresponding Manage Device icon.
3.
Click Remove, and then in the confirmation dialog box, click Remove again.
* 
NOTE: Ensure that you remove the RDA device from NetVault Backup before you delete the container from the DR Series system. You must force remove the RDS device from NetVault Backup, if you delete an RDS container from the DR Series system before removing it from the NetVault Backup server.
4.
If NetVault Backup fails to remove the device, select the Force Removal check box in the confirmation dialog, and click Remove.

The selected RDS device is removed from NetVault Backup. The RDS container can now be removed from the DR Series system.
