Migrating savesets and backup jobs

1
Make sure that you have added the Linux-based QoreStor device to the NetVault Backup Server.
For more information, see Quest DR Series systems or Quest QoreStor.
2
Make sure that the NetVault SmartDisk device and the QoreStor device are online and assigned to the same NetVault Backup Server.
a
In the Navigation pane, click Manage Devices.
b
On the Manage Devices page, note the status of the NetVault SmartDisk device and the QoreStor device.
Figure 9. Devices are online
3
Verify that the applicable backup savesets are pointing to the online NetVault SmartDisk device.
a
In the Navigation pane, click Explore Storage.
b
On the Explore Storage page, click Explore Disk Storage.
c
On the Explore Disk Storage page, select the applicable device in the repository table, and click Explore Repository.
d
On the Explore Disk Storage Repository page, review the information listed in the Saveset table.
e
To close the dialog box, click Close.
f
Repeat these steps for each saveset that you want to migrate from NetVault SmartDisk to a QoreStor device.
4
When you are ready to start the migration process, click Manage Devices in the Navigation pane.
5
Click the Manage Device icon for the NetVault SmartDisk device.
6
On the RAS Device Management page, click Start Migration.
7
In the Select target device dialog box, select the QoreStor device to which you want to migrate the NetVault SmartDisk saveset.
8
Select an existing Target Set or create a new Target Set that saved or scheduled backup jobs should target, and click Confirm.
9
To monitor the progress of the migration, click Check logs.

The View logs page displays all NetVault Backup logs. To view only the NetVault SmartDisk, enter NVSD in the text box. The process is displayed as a percentage of the savesets that have been migrated.

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.

Data Domain System prerequisites

Before adding a Data Domain system to a NetVault Backup Server, verify that the following requirements are met:

•
Install DD Boost license on the Data Domain System: To use a Data Domain system for backups and restores, install the required DD Boost license and enable DD Boost on the Data Domain systems.
•
Create a DD Boost user account: On the Data Domain system, create a DD Boost user account that can be used to log on to the device for backups and restores.
•
Configure the required DD Boost features: On the Data Domain system, configure the features that you want to use. For more information about enabling and configuring DD Boost features, see the DD Boost section in the DD OS Administration Guide.
•
Open the required firewall ports: To perform DD Boost backups and replication across a firewall, open the following ports on the Data Domain system:
•
TCP 2049 (NFS)
•
TCP 2051 (Replication)
•
TCP 111 (NFS portmapper)
•
TCP xxx (select a random port for NFS mounted)
•
Install Microsoft Visual C++ 2005 SP1 Redistributable Package on Windows: Install the Microsoft Visual C++ 2005 SP1 Redistributable Package on Windows-based NetVault Backup Server. This requirement applies to all supported Windows platforms. The DD Boost library fails to load if you do not install this package on Windows.
•
Configure network time-outs: Backup and restore jobs often take a long time to complete. Although the DD Boost Library can recover from temporary network interruptions, the operating system on the data protection application system might terminate a job prematurely if the data protection application time-outs are set too low. To avoid this, Data Domain recommends setting time-outs to at least 30 minutes (1800 seconds).
