b
Under Copy Type, configure the following options.
 
Option
Description

Copy a full backup to produce a new independent copy of the data

This option is recommended when you want to create a copy for off-site storage.

The Data Copy method breaks down the backup into segments and copies the segments to the backup device. During restore, either the primary backup or the secondary copy is used to recover data. The segments from the primary backup and secondary copy are not interchangeable. Therefore, it is possible to enable encryption for the Data Copy when the primary copy is unencrypted. This option is useful when you want to use the deduplication option for the primary backups.

 

The Data Copy option can be used to create a copy of the Full as well as Incremental Backups. This method removes all links between the Full and Incremental Backups, and allows you to set a new retention period for the copy.

NOTE: Before creating a Data Copy of regular Incremental Backup, you must have created a copy of the initial Full Backup and the previous Incremental Backups in the backup sequence. Otherwise, the plug-in reports an error. For more information, see Important notes.

Duplicate a backup

This option is recommended when you want to migrate the saveset to different media.

The Duplicate method creates an exact copy which is linked to the original backup. This method breaks down the backup into segments and copies the segments to the storage device. During restore, the segments from the primary backup and secondary copy are interchangeable. As it is not possible to mix unencrypted segments with encrypted segments during restore, you cannot enable or disable encryption for the Duplicate. If the original saveset is encrypted, the Duplicate method creates an encrypted copy. If the original saveset is not encrypted, this method creates an unencrypted copy.

This option can be used to create a copy of the Full as well as Incremental Backups. The savesets created using the Duplicate method automatically share the original saveset’s name and reference.

NOTE: When restoring copies of Incremental Backups, NetVault Backup requires the original Full Backup. On the Create Restore Job page, only one saveset is listed for the original and duplicate backup.

Use saveset name from original backup

By default, the plug-in assigns a new saveset name to a copy created using the Copy a full backup to produce a new independent copy of the data option. This name is derived from the Job Name.

If you want to use the original saveset name for such copies, select this check box.

Allow streams to share media

This check box is not selected by default. You can use this option with the Duplicate a backup method.

When creating a Duplicate of a multi-stream backup, you can use this option to convert multiple data streams into a sequential data stream. If you do not select this check box, each stream is written separately.

If you are using a disk-based device to store the Duplicate backup, multiple streams are recommended. For such jobs, there is no need to select this check box.

If you do not select the Allow Streams to Share Media check box for tape devices, each data stream targets a separate media item. Any tape that is used to write a stream is excluded from the allowable media items. If enough tapes are not available for the job, the job fails. When using tape devices to store the Duplicate backups, you can select this check box to use minimal media items.

Automatically get a set's last full backup

You can use this option with the Backup Sets method to create a copy of the last Full Backup that was performed using a particular Backup Selection Set.

The Incremental Backups are not copied when you select this option.

Use a set's most recent job regardless of type

You can use this option with the Backup Sets method to create a copy of the last backup, regardless of its type (Full or Incremental Backup).

This option allows you to create copies of Incremental Backups.

NOTE: When you use this option, you must run the data copy job before the next primary backup (Full or Incremental) for that backup sequence is run; otherwise, the plug-in creates a copy of that primary backup.

Tagname

When you create multiple copies of an Incremental Backup Sequence, you must provide a tag can be used to identify each copy. A tag can contain any string value. Without a tag, the plug-in cannot distinguish between the multiple copies of a backup sequence.

On the data selection page for restore, the savesets created with the Plug‑in for Data Copy are labeled as follows:

•
Data copies created without a tag:
<Saveset Name> — DataCopy of <Selection Set Name> (Saveset <#>) <Timestamp>
•
Data copies created with a tag:
<Saveset Name> — DataCopy of <Saveset #>, Tag '<User Tag>' (Saveset <#>) <Timestamp>

Example:

The following example explains how to use this option.

1
Create a Backup Selection Set, and perform a Full Backup using the set.
2
Create a copy of the set using device 1. While creating the copy, specify a unique Tagname on the Data Copy Options page.
3
Create a second copy of the set using device 2. While creating the copy, specify a unique Tagname on the Data Copy Options page.
4
Perform an Incremental Backup for the set.
5
Repeat steps 2 and 3 for the Incremental Backup.
6
On the data selection page for restore job, both the original backup and two copies of the backup sequence are displayed.
7
To restore data from a specific copy, select the applicable saveset. You can identify a copy using its Tagname.
c
Configure the required additional options.
 
Option
Description

Migrate (Discard original backup)

To migrate the backup instead of creating a copy, select this check box. After copying the data, NetVault Backup deletes the index for the original backup.

NOTE: When creating copies of the Plug-in for FileSystem backups, the Migrate option can only be selected for Full Backups that do not have any associated Incremental or Differential Backups. If you select this option for a Full Backup that has an associated Incremental or Differential Backup, NetVault Backup creates the secondary copy successfully, but it does not delete the index for the primary or original backup. For such backups, after creating the copy, you must manually retire the primary or original backup.

Use optimised replication between devices that support this feature

Optimized replication enables transfer of deduplicated data directly from one device to another device of the same type during a Data Copy or Duplicate operation. It provides an efficient method to create secondary copies and offers the following advantages:

•
Copies data in its deduplicated form, which greatly reduces the amount for data transferred over the network.
•
Copies data directly from the source to the destination without using any resources on the NetVault Backup Server.

The following storage devices support optimized replication:

•
Quest DR Series Systems: To perform optimized replication, both the source and target Quest DR Series systems must be running the same release version of the DR OS. Replication is not supported between systems that run different releases of the OS.
For example, to replicate data from a source system that is running DR OS 3.x, the target system must be running the same OS release version. Replication is unsuccessful if the target system is running DR OS release 2.0.x or 3.0.x.
NOTE: When optimized replication and backups are performed simultaneously on a Quest DR Series system, the backup throughput is affected.

 
•
NetVault SmartDisk devices: To perform optimized replication, you require NetVault SmartDisk 2.0 or later.
If the login credentials configured for the source and destination NetVault SmartDisk Servers do not match, replication fails. To ensure a successful replication, do one of the following:
- Disable WebDAV authentication on both NetVault SmartDisk Servers.
- Enable WebDAV authentication only on the source server.
- Configure the same login credentials on both servers.
NOTE: When copying a backup from a NetVault SmartDisk to a different device type (for example, VTL, Quest DR Series System, or Data Domain System), you must clear this check box. If you do not clear this check box, the Data Copy or Duplicate job fails or stops responding.
•
DD Boost-enabled Data Domain Systems: The secondary copy backups between two DD Boost-Enabled Data Domain Systems use the managed file-level replication feature provided by DD Boost.
File-level replication requires the DD Boost Replicator license, which must be installed on both the source and destination Data Domain systems.
NOTE: 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.

Acquire Source Media before Target Media

When you select this check box, the Plug-in for Data Copy tries to acquire the source media before it attempts to acquire the target media for the Data Copy and Duplicate backups.

Maximum Streams for Data Copy

Type or select the maximum number of parallel streams that can be generated for the Data Copy job. By default, a single data stream is generated to copy the data items in a sequential manner.

Media Request Timeout

Type or select the amount of time NetVault Backup waits for the backup media. This timeout value is specified in number of minutes. If the required piece of media is not available within the specified interval, the job is aborted.

The default value is 10 minutes. If you set the value to zero (0), the Data Copy job waits indefinitely until the media is provided or the job is manually aborted.

The maximum timeout period that can be set is 1440 minutes (24 hours), which ensures that current instance is aborted before NetVault Backup runs the next instance of a Daily job.

NOTE: The media request timeout for Phase 1 Data Copy jobs (created using the Plug-in for Data Copy) is controlled by the Media Request Timeout setting in the Backup Options Set; it is not controlled by the Media Request Timeout setting in the Target Set. The media request timeout for Phase 2 (Secondary Copy) Data Copy and Duplicate jobs is controlled by the Media Request Timeout specified in the Backup Advanced Options Set

Run data copy on client

By default, the Data Copy job runs on the NetVault Backup Server. To run the job on a different NetVault Backup machine, select the client in the list.

d
Under Backup Life, configure the following options.
 
Option
Description

Use originals life

To use the original saveset’s retention period, select this option.

Use 'Backup Life' on 'Advanced Options' tab

To set a different retention period for the data copy, select this option, and then specify the retention period in the Backup Advanced Options set. For more information about these options, see the Quest NetVault Backup Administrator’s Guide.

e
Click Save, and in the Create New Set dialog box, type a name for the set. Click Save to close the dialog box.
5
Select or create the Schedule Set, Source Set, Target Set, and Advanced Options Set. For more information about these sets, see the Quest NetVault Backup Administrator’s Guide.
 
* 
NOTE: When performing Duplicate and Data Copy backups, you cannot use media items that contain the original saveset or a copy of the same backup. NetVault Backup excludes these media items to ensure that copies and original backup do not exist on the same media item.

The concept of media does not apply to disk-based devices. If the original saveset is stored on a disk-based device, NetVault Backup does not exclude that device when you run a Duplicate or Data Copy job for that backup.

 
* 
NOTE: When performing multi-stream backups, do not select the Ensure backup is the first on the target media check box. If you select this check box for multi-stream backups, each data stream targets a separate piece of media to exist as the first backup on the media item. Thus, if a backup generates five streams, the job tries to obtain five blank or new media items.

This option does not apply to disk-based storage devices.

6
To submit the job for scheduling, click Save & Submit. You can monitor the job progress from the Job Status page and view the logs from the View Logs page.
To save the job definition without scheduling it, click Save. You can view, edit, or run this job from the Manage Job Definitions page. This job is not displayed on the Job Status page until you submit it.
For more information about Job Status, View Logs, and Manage Job Definitions, see the Quest NetVault Backup Administrator’s Guide.

Important notes

•
When you create a Data Copy of any backup sequence, you must create a copy of each backup in the sequence to maintain data integrity of the copy. If you try to create a copy of an Incremental Backup without creating a copy of the original Full Backup or previous Incremental Backup, the job reports the following error and fails:
“Cannot DataCopy this incremental as the previous DataCopied backup it depends on is missing. Please ensure the entire series has been DataCopied.”
•
The Plug-in for FileSystem supports two types of Incremental Backups: Regular Incremental Backups and Dump Type Incremental Backups.
•
Regular Incremental Backups are linked to the initial Full Backup and the previous Incremental Backups. Before creating a Data Copy of a regular Incremental Backup, you must have created a copy of the initial Full Backup and the previous Incremental Backups in the backup sequence. Otherwise, the plug-in reports an error.
•
Dump Type Incremental Backups are standalone Incremental Backups. You can copy these backups without creating a copy of any other backup in the backup sequence.
•
The Advanced Backup Option Enable Encryption can be used only with the Copy a full backup to produce a new independent copy of the data option.
If the primary copy is encrypted, the Data Copy method automatically creates an encrypted saveset whether you select the Enable Encryption check box or not. Therefore, this option is only useful when you want to create an encrypted secondary copy from an unencrypted primary copy.
Encrypted primary backups are not encrypted again if you select the Enable Encryption check box.
To restore data from an encrypted Data Copy, you must use the primary copy’s Encryption Key
•
The option Automatically get a set's last full backup is incompatible with the backups performed using NetVault Backup Plug-in for NetWare. The Plug-in for Data Copy creates a copy of the last backup regardless of its type (Full or Incremental).
•
The Plug-in for Data Copy cannot distinguish between the NDMP Level 0 Full Backup and Levels 1–9 Incremental Backups. An NDMP backup of any level appears as Full Backup to the Plug-in for Data Copy. So, if you are trying to make a copy of the latest saveset, and you have selected the options Copy a full backup to produce a new independent copy of the data and Automatically get a set's last full backup, the Plug-in for Data Copy still creates a copy of the last backup (of any level). It does not create a copy of the Level 0 backup for that Backup Selection Set.
•
On NetVault Backup Server 10.0.5 and later, the Plug-in for Data Copy creates index version 4, which is incompatible with earlier versions of NetVault Backup. A client running NetVault Backup 10.0.1 or an earlier version cannot read these index files. To restore Data Copy savesets generated from NetVault Backup Server 10.0.5 or later, the client must also be running NetVault Backup 10.0.5 or later.

Restoring a Data Copy

For a restore job, you can use either the original saveset or a Data Copy. The procedure for restoring data is the same for the original saveset and the data copy saveset, and depends on the plug-in used to create the original saveset. For information about restoring the data, see the relevant plug-in user’s guide.
