About NetVault SmartDisk

NetVault SmartDisk provides disk-based storage with optional data deduplication capability.

NetVault SmartDisk uses byte-level, variable block-based software deduplication, which packs up to 12 times more data into the same storage area for a 92 percent reduction in storage footprint. NetVault SmartDisk is installed and licensed separately from NetVault Backup.

A NetVault SmartDisk instance consists of one or more Storage Pools and a set of processes that perform backup and deduplication operations. A Storage Pool consists of one or more file system volumes, which can be easily extended by adding more file system paths. An instance can accept data streams from heterogeneous platforms.

You can install a NetVault SmartDisk instance that has deduplication enabled (the default mode) on a dedicated NetVault SmartDisk Server or a NetVault Backup Client. (If deduplication is enabled, you cannot install NetVault SmartDisk on the NetVault Backup Server.) If deduplication is disabled, you can also select the NetVault Backup Server as the host machine.

For more information about installing and configuring NetVault SmartDisk, see the Quest NetVault SmartDisk Installation Guide and Quest NetVault SmartDisk Administrator's Guide.

Adding a NetVault SmartDisk

To use a NetVault SmartDisk for backups and restores, you must first add the device to the NetVault Backup Server. You can use the configuration wizard to add and configure this device.

To add a NetVault SmartDisk to the NetVault Backup Server:
1
In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Add Storage Devices.
— or —
In the Navigation pane, click Manage Devices, and then click Add Device.
2
On the Add Storage Devices page, select the NetVault SmartDisk option, and click Next.
3
On the Add NetVault SmartDisk Instance page, provide the following details.

Option
Description

Network name/IP address

Type the Fully Qualified Domain Name (FQDN) or IP address of the host on which NetVault SmartDisk is installed. You must provide this information even if the device is deployed on the NetVault Backup Server.

If the server is unable to resolve the host name, it fails to add the device.

Network port

The default value for this setting is zero (0). If the device is listening on the default port, do not change this value.

If the device is listening on a non-default port, type the port number configured as the Network Settings:Remote Listen Port in the percolator.cfg file. For more information about configuring a non-default port for a NetVault SmartDisk, see the Quest NetVault SmartDisk Administrator’s Guide.

Force add

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.

Configure WebDAV credentials

To prevent unauthorized access to data, you can set up WebDAV authentication for server requests on NetVault SmartDisk. NetVault SmartDisk uses Digest Access Authentication with WebDAV. For more information about setting up authentication on the NetVault SmartDisk Server, see the Quest NetVault SmartDisk Administrator’s Guide.

If WebDAV authentication is enabled on the NetVault SmartDisk, select this check box, and provide the following information:

•
Username: Specify the user account configured on the NetVault SmartDisk Server.
•
Password: Type the password for the user account.
•
Confirm Password: Type the password again for confirmation.
NOTE: If you enable WebDAV authentication on the NetVault SmartDisk Server, but do not configure the authentication details on the NetVault Backup Server, the backups and restore operations using that device fail without reporting any proper error messages. The scan operation also fails for the device.
NOTE: NetVault Backup does not provide any method to disable WebDAV authentication once it has been enabled for a NetVault SmartDisk. The only way to disable WebDAV authentication is to remove the NetVault SmartDisk from the NetVault Backup Server, and add the device again.
4
Click Next to add the device.
5
After the device is successfully added and initialized, a message is displayed.

About EMC Data Domain Systems

EMC Data Domain Systems provide disk-based storage with inline deduplication capabilities that reduce storage requirements by 10 to 30 times.

NetVault Backup provides seamless integration with Data Domain systems through the EMC DD Boost™ software, allowing you to minimize your backup window and perform optimized disk-based backups while reducing your storage and network bandwidth requirements.

 
* 
NOTE: The NetVault Backup Starter Edition does not support DD Boost.
DD Boost components

The DD Boost software includes two components:

•
DD Boost Library: This component runs on the NetVault Backup Server, and provides the interface to communicate with the DD Boost Server running on the Data Domain system.
•
DD Boost Server: This component runs on the Data Domain systems.
DD Boost features

DD Boost offers the following features:

•
Distributed segment processing: DD Boost offloads parts of the deduplication process to the backup client or server, enabling the client or server to send only unique data segments to the Data Domain system.
Distributed segment processing offers the following advantages:
•
It increases the aggregate backup throughput of the storage system and reduces the amount of data transferred over the network.
•
It decreases processor utilization on the backup server because sending data over the network is more CPU‑intensive than the distributed deduplication process.
Without this feature, the DD Boost Library sends all data (unique or redundant) to a Data Domain system for deduplication processing.
•
Advanced load balancing and link failover: This feature lets you combine multiple Ethernet links into a group, and register a single interface with the backup application. The Data Domain system automatically balances the load for backup and restore jobs on multiple interfaces, and routes the jobs to the available interfaces if one of the interfaces in the group goes down.
•
File replication: File-level replication enables transfer of deduplicated data directly between two or more DD Boost-enabled Data Domain systems, and thus reduces WAN bandwidth requirement by up to 99 percent. The Data Domain systems create and transfer the duplicate copies without using any resources on the backup server.
Replication requires optional DD Boost Replicator license. The license must be installed on all participating Data Domain systems.
If the source and target Data Domain systems are running different versions of the Data Domain OS, then for replication to be successful, the target system must be running the higher version of the OS.
