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 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.

Click Next to add the device.

After the device is successfully added and initialized, a message is displayed.

Migrating savesets and backup jobs from NetVault SmartDisk to QoreStor

Use the migration feature to move savesets and backup jobs from NetVault SmartDisk device to QoreStor. As part of migration, all saved and scheduled backup jobs are redirected from the targeted NetVault SmartDisk device to the targeted QoreStor device. This process is completed before the data from existing backups is migrated.

Important notes
•
QoreStor is only supported on Linux-based platforms.
•
All savesets associated with a specific NetVault Backup Server and NetVault SmartDisk are migrated to the new target. You cannot select specific savesets.
•
Although migration moves the backup and saveset data to a QoreStor device, NetVault Backup does not delete the data from NetVault SmartDisk. Additionally, you cannot use NetVault Backup to delete the data from NetVault SmartDisk after migration is finished; you must manually delete the data.
•
The Expire All function is automatically disabled during the migration process. However, it is not disabled on the new target.
•
If migration fails or you manually stop the process, savesets that were already migrated automatically point to the new target. If you restart migration, only savesets that have not been migrated yet are addressed. Additionally, corresponding backup jobs are also automatically updated to point to the new target; they do not revert to the original target even if migration of the applicable savesets is interrupted.
If migration of a specific saveset fails, you can run migration again after the first pass is finished. Depending on the reason for the failure, the remaining savesets might complete migration on the subsequent pass.
•
If you interrupt the migration process to select a different target, you must manually update the backup jobs that have been redirected to point to the new target.
•
Although NetVault Backup does not limit the number of migrations that you can perform simultaneously, Quest recommends that you process each migration separately.
•
You can migrate multiple savesets from different NetVault SmartDisk devices to the same QoreStor device if the target contains sufficient space. If space is not available, migration fails.
•
You can migrate the same saveset to different QoreStor devices; however, the saveset points to the last QoreStor device that you selected.
•
During the migration process, Quest strongly recommends that you avoid initiating a backup job that targets the NetVault SmartDisk device that you are migrating.
•
You can create up to five storage groups and 16 containers across all storage groups.
QoreStor does not support multi-tenancy.
•
NetVault Backup does not support migration of a Secondary Copy from one type of RDA Device to another.
If you use a Duplicate method of a Phase 2 backup job to create a Secondary Copy that also targets a NetVault SmartDisk device, the job might fail after migration is finished. This occurs when both jobs targeted a NetVault SmartDisk device. During migration, the primary job is migrated to the new target, such as a QoreStor device, and the backup job completes successfully. The secondary job still identifies a NetVault SmartDisk device as the target, which causes it to fail.
•
You can use the Secondary Copy feature with different RDA device types, but you cannot use it with an RDA device and a NetVault SmartDisk device. You must create a new Secondary Copy that uses an RDA device as the target.
