Creating Backup Advanced Options Sets

An Advanced Options Set is used to specify backup retirement settings, Secondary Copy job definitions, and other advanced options. You can create a Backup Advanced Options Set from the Create Backup Job page.

1
Start the backup job wizard, and click Create New next to the Advanced Options list.
2
On the Advanced Options page, click the corresponding button, and configure the options described in the following sections:
3
Click Save, and in Advanced Options Set Name, type a name for the set.
Click Save to save the Advanced Options Set.

Setting backup retirement options

1
On the Advanced Options page, click Backup Life, and configure the following settings.

Archive

To create an archive, select this option.

An archive cannot be used as a base for Incremental or Differential backups. When archiving data, you must always select the Full Backup type. If you select Incremental or Differential Backup type, the restore job fails.

Backup

This option is selected by default. To create a backup, use this option.

Backup Life

This option specifies how long a backup is retained.

A backup can be retained indefinitely or retired after a specified period. NetVault Backup supports generation- and time-based retirement methods for backups. For more information about backup retirement methods, see Backup retirement.

You can specify the retirement options in the Backup Advanced Options Set. Alternatively, you can use the Change Expiry method to set or change the expiry date or generation count for existing savesets. For more information about the Change Expiry method, see Configuring saveset expiry options.

To set the Backup Life option, do the following:

Backup life — based on Full Backup count: To configure generation-based retirement, select the Discard After Full Backup Count option. In the associated list, type or select the maximum number Full Backups that you want to retain.
Backup life — based on time: To configure time-based retirement, select the Discard After option. Type or select the period, and in the associated list, select the Days, Weeks, Months, or Years option.
By default, the Backup Life option is set to Discard After and the retirement period is set to three months.

 

Force Expiry: By default, if a backup has any dependent backups, its retirement is deferred until all dependent backups are ready for retirement.
To apply this rule globally to all backups, you can modify the Media Manager settings. For more information, see Configuring retirement rules for dependent backups. If the Retirement Timing Control option is set to Force Always, the Force Expiry is option is used, regardless of state of this check box.
Retain a backup indefinitely: To retain a backup indefinitely, select the Don't Discard based on Full Backup Count and Don't Discard based on Time options.

 

NOTE: If you set both Discard After Full Backup Count and Discard After options for a Full Backup, the backup is retired only when both conditions are met. For example, if you set the Discard After Full Backup Count option to four Full Backups and the Discard After option to 30 days, the backup is retired after five Full Backup counts and 30 days.

Offline Index After

Online backup indexes allow you to quickly scan through the contents of a saveset without loading the media. However, these indexes can increase the overall size of the NetVault Database. To manage the database size, you can delete the online indexes.

You can use different methods to delete online indexes:

You can configure the Offline Index After option in the Backup Advanced Options Set to automatically delete the online index for a backup after the specified period. This method is described in this section.
You can use the Days of inactivity before an index is offlined setting to configure a global policy for deleting online indexes after a specified period of inactivity. For more information, see Configuring Media Manager settings for backup indexes.

To specify the index retention period in the Backup Advanced Options set, select Offline Index After option. Type or select the length of time that you want to retain the index, and in the associated list, select the Days, Weeks, Months, or Years option.

Specifying additional options

1
On the Advanced Options page, click Additional Options, and configure the following settings.

Enable Encryption

NetVault Backup provides two encryption plug-ins:

NetVault Backup Plug-in for Standard Encryption (Plug-in for Standard Encryption)
NetVault Backup Plug-in for Advanced Encryption (Plug-in for Advanced Encryption)

These plug-ins provide support for CAST-128, AES-256, and CAST-256 algorithms to meet regulatory backup security requirements. For more information about these plug-ins, see the Quest NetVault Backup Plug-in for Standard Encryption User’s Guide or Quest NetVault Backup Plug-in for Advanced Encryption User’s Guide.

Once the Plug-in for Standard Encryption or Plug-in for Advanced Encryption is installed on a client, you can do either of the following:

The job-level encryption option is useful in the following situations:

To perform job-level encryption for a primary backup, select the Enable Encryption check box. For more information about using job-level encryption for a secondary copy, see Encrypt Secondary Copy Only.

Enable Deduplication

Deduplication is enabled by default. Clear this check box if the target device does not support data deduplication.

When performing backups to devices that support deduplication, we recommend that you clear this check box for the following jobs:

Incremental Backups that you want to consolidate using the Plug-in for Consolidation. By not selecting this option, you eliminate the unnecessary overhead of rehydrating the deduplicated Incremental Backups during the consolidation process. You can enable deduplication while backing up the Consolidated Full Backup.

Verify After Backup

To verify the stream length written to the media and ensure that no blocks were dropped during backup, select this check box.

Backup verification is performed as Phase 2 job after the actual backup is completed. If any dropped blocks are detected, the verification phase reports an error and fails. You must run the backup again if the verification phase fails.

By default, the verification job runs on the NetVault Backup Server. To configure a different client to run the verification phase, see Configuring default settings for Verify Plug‑in.

Use Network Compression

To use network compression while transferring data over the network, select this check box.

The data is compressed on the backup client before being transferred over the network. On the machine to which the target device is attached, the data is decompressed before being written to the media.

Network compression does not work for the following types of jobs:

Backups performed using the NetVault Backup Plug-in for NDMP, NetVault Backup Plug-in for NetWare, and NetVault Bare Metal Recovery products

Creating a Secondary Copy

1
On the Advanced Options page, click Secondary Copy.
2
Click the Create Secondary Copy check box, and configure the following settings.

Copy with

Select the method that you want to use to create the Secondary Copy. The available methods are:

For more information about these methods, see Secondary Copy.

NOTE: 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.

Run copy job on

By default, the secondary copy job runs on the NetVault Backup Server. If you want to run the job on a particular client, select the target client.

You can use this option to perform backups on a client with a locally attached physical or virtual tape device.

Use Schedule Set

Select an existing Schedule Set, or click Create New, and configure the schedule type and schedule method. For more information, see Creating Schedule Sets.

NOTE: You cannot use the Repeating and Triggered schedule types to run Secondary Copy jobs. A Secondary Copy job can run only after the Phase 1 job completes successfully. The Repeating and Triggered schedule types can cause a situation where a Secondary Copy job is configured to start before the source saveset is available.

Use Target Set

Select an existing Target Set, or click Create New, and configure the target device and media options for the job. For more information, see Creating Target Sets.

Use Source Set

Select an existing Source Set, or click Create New, and configure the source device options for the job. For more information, see Creating Source Sets for backup jobs.

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. The timeout value is specified in number of minutes. The default value is 10 minutes.

If the required media item is not available within the specified interval, the job is automatically aborted.

If you set the value to zero (0), the Secondary 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.

Encrypt Secondary Copy Only

To perform job-level encryption for a secondary copy, select the Enable Encryption check box.

This option can only be used with the Data Copy method. To use this option, the Plug-in for Standard Encryption or the Plug‑in for Advanced Encryption must be installed on the client.

Note the following:

If the primary copy is encrypted, the Data Copy method automatically creates an encrypted saveset whether you select the Encrypt Secondary Copy Only 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 Encrypt Secondary Copy Only check box for a Data Copy.

For more information about using job-level encryption for a primary backup, see Enable Encryption.

Migrate (Discard Original)

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.

Allow Streams to Share Media

This check box is not selected by default.

When creating a Duplicate or Data Copy 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 or Data Copy 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 or Data Copy backups, you can select this check box to use minimal media items.

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:

The following storage devices support optimized replication:

Dell DR Series Systems: To perform optimized replication, both the source and target Dell 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.
NetVault SmartDisk devices: To perform optimized replication, you require NetVault SmartDisk 2.0 or later.
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.

Select Source Media Before Target Media

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

Use Life of Original

This option is selected by default. To use the original saveset’s retirement period, leave this option selected.

Discard After

To configure a different retirement period for the Duplicate or Data Copy saveset, select this option.

Type or select the length of time that you want to retain the backup, and in the associated list, select the Days, Weeks, Months, or Years option. You can set only time-based retirement period for the copy.

Force Expiry

This check box is displayed when you select the Discard After option.

By default, if a Secondary Copy has any dependent backups, its retirement is deferred until all dependent backups are ready for retirement.

You can select this check box to retire a Secondary Copy according to its retirement schedule. Forcing this behavior can cause early retirement of dependent Incremental and Differential Backups.

To apply this rule globally to all backups, you can modify the Media Manager settings. For more information, see Configuring retirement rules for dependent backups. If the Retirement Timing Control option is set to Force Always, the Force Expiry option is used, regardless of state of this check box.
