Quest QoreStor

Quest QoreStor is software-defined storage that provides deduplication, compression, and replication support. As a result, you can retain more backup data for a longer period in the same footprint.

 
* 
IMPORTANT: QoreStor is only supported on Linux-based platforms.

QoreStor uses the Plug-in for RDA to integrate its data-storage operations with NetVault Backup. This plug-in is automatically installed on the NetVault Backup machines when you install the NetVault Backup Server or Client software.

While QoreStor supports the RDAv2 and RDAv3 protocols, NetVault Backup uses the RDAv2 protocol to communicate with QoreStor. QoreStor also uses a secured connection to NetVault Backup, which ensures protection of your data as it moves between NetVault Backup to QoreStor.

Before you can add and use QoreStor, you must install the applicable software. For more information, see the Quest QoreStor Installation Guide.

Secure Connect

Secure Connect encompasses a set of client and server components that creates a secure channel for QoreStor communication with WAN-connected clients that is also resilient to WAN outages. For more information, see the Quest QoreStor Installation Guide.

Secure Connect between NetVault Backup is enabled by default upon setup; however, you can disable Secure Connect using the sc_manager script, if that is your preference.

For a Linux client, the location of the script is /usr/netvault/dynlib/sc_manager. To disable the script, set the manager status to false.

For a Windows client, the location of the script is C:\Program Files\Quest\NetVault Backup\dynlib\sc_manager.

Table 32. Add a container as a media for QoreStor
Option
Description

Storage Group Name

Select the name of the storage group.

Container

Select the name of the storage container.

Block size

The default block size is 512 KiB. The block size cannot be changed for Quest QoreStor systems.

Stream Limit

The default value for this setting is 64streams. This setting applies to all NetVault Backup Servers to which the container is added. If the number of data streams exceeds the defined limit for the container, the Media Manager reports an error (“Device has too many streams”).

You can set the soft stream limit to any value between 1 and 512.

NOTE: You must consider target device capability before changing stream limit value for QoreStor.

If the container is added to more than one NetVault Backup Server, set the same soft stream limit on all servers.

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.

* 
NOTE: The Quest QoreStor Series systems support three deduplication modes:
•
Passthrough: When this mode is selected, deduplication processing occurs on the Quest QoreStor system. The passthrough mode requires at least 200 MB of free memory on the NetVault Backup Client.
•
Optimized: When this mode is selected, deduplication processing occurs on the NetVault Backup Client. The Optimized mode requires at least 4 GB of free memory on the NetVault Backup Client.
•
Auto: When this mode is selected, NetVault Backup decides the deduplication mode (Passthrough or Optimized) based on the criteria for Passthrough and Optimized.
