Guidelines for using RDA with NetVault Backup and with vRanger For best results, observe the following guidelines for optimal performance with your supported RDA with NetVault Backup and RDA with vRanger operations with the DR Series system: • Backup, restore, and optimized duplication operations are performed using the RDA with NetVault Backup or RDA with vRanger plug-in. NOTE: The plug-in is installed on client systems to support client-side deduplication. • Deduplication. The DR Series system supports two deduplication modes: - Passthrough: When this mode is selected, deduplication processing occurs on the DR Series system. Passthrough writes occur when data is sent from a media server to the DR Series system without applying any optimization to the data. NOTE: Passthrough mode requires at least 200MB of free RAM on the backup client. - Dedupe: When this mode is selected, dedupe writes occur when data is sent from a media server to the DR Series system after optimization is applied to the data; deduplication processing would occur on a NetVault Backup client, for example. NOTE: Dedupe mode requires at least 4GB of free RAM on the DR Series system.

Guidelines for using RDA with NetVault Backup and with vRanger
For best results, observe the following guidelines for optimal performance with your supported RDA with NetVault
Backup and RDA with vRanger operations with the DR Series system:
•
Backup, restore, and optimized duplication operations are performed using the RDA with NetVault Backup or RDA
with vRanger plug-in.
NOTE:
The plug-in is installed on client systems to support client-side deduplication.
•
Deduplication. The DR Series system supports two deduplication modes:
–
Passthrough
: When this mode is selected, deduplication processing occurs on the DR Series system.
Passthrough writes occur when data is sent from a media server to the DR Series system without applying any
optimization to the data.
NOTE:
Passthrough mode requires at least 200MB of free RAM on the backup client.
–
Dedupe
: When this mode is selected, dedupe writes occur when data is sent from a media server to the DR
Series system after optimization is applied to the data; deduplication processing would occur on a NetVault
Backup client, for example.
NOTE:
Dedupe mode requires at least 4GB of free RAM on the DR Series system.
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.
