NetVault 13.1.2 - Administration Guide


	NOTE: Disk-based devices (RAS devices) are considered network-attached or non-local devices. A local device is given priority over a disk-based (RAS) device; a local VTL or SCSI device is given priority over a local NDMP filer-attached device. If you select the Any Device option, NetVault tries to find a suitable local device (local to the NetVault client). To use any other device, you can set a higher media request weight for that device. For more information about media request weightings, see Configuring media request weightings.

Option

Description

Storage Tier

Optionally, select a storage tier from the drop-down list.

For information about how to create a storage tier, see Creating a storage tier.

NOTE: If you select a Storage Tier and select Target Media By Media in group, then only media common to both selections will be used as a target.

Target Media By

Select one of the following options:

•

Any media not in a group: This option is selected by default. To use media items that do not belong to any media group, leave this option selected.

•

Any media: To use any suitable media item regardless of its group association, select this option.

•

Specific media ID: To use particular media items, select this option. In the list of media items, select the label for the target media.

•

Media in group: To use media items that belong to a particular media group, select this option. In the list of media items, click the group label for the target media. Media group labels are case‑insensitive.

NOTE: When selecting a target storage set, if you select Specific Media ID, then the storage tier will become disabled and set to the default empty storage tier.

Performance

To configure Media Manager to prioritize targets for optimal efficiency, select Optimize target selection for best deduplication.

With this option, Media Manager examines the length of each segment in a backup job to determine the best media target to use.

Label Media

To automatically label blank media items during backup, select Automatically Label BLANK Media.

By default, NetVault assigns a system-generated label to blank media. The label consists of the NetVault Server Name, the current date, and a seed number.

You can configure NetVault to use media barcodes as the default labels. For more information, see Configuring general settings for Media Manager.

NOTE: If a piece of media that previously appeared to contain data becomes unexpectedly blank, it is marked as “suspect” to ensure that auto‑labeling does not occur for it. NetVault does not permit the use of same label, whether user-specified or system-generated, to ensure that only one label is associated with a piece of media. A notification event occurs when any piece of media becomes unexpectedly blank.

Reuse media

Select the appropriate option from the following:

•

Never: This option is selected by default. To ensure that media marked for re-use are not used for backup, leave this option selected.

•

Any: To allow any suitable reusable backup media regardless of the group association, select this option.

•

With the same group label as target media: To reuse media that belong to same media group as the target media, select this option. This option can only be set if you have specified a group label for the Target media by option.

NOTE: A piece of media is automatically marked for reuse when the last saveset stored on it is retired. To manually mark a piece of media for re‑use, see Marking a tape for reuse.

Media Request Timeout

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

The default value is zero (0). With the default setting, the 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 runs the next instance of a Daily job.

NOTE: The timeout interval for media requests cannot be less than 5 minutes. The interval is automatically set to the nearest 5 minutes, if you specify a value that is not a multiple of 5. For example, if you specify 8 minutes, the timeout value is set to 10 minutes, and if you specify 23 minutes, the timeout value is set to 25 minutes.


	NOTE: Backups to disk-based devices are stream-oriented. The concept of media does not apply to disk-based devices. The media options Target Media By, Label Media, and Reuse Media do not apply to disk-based storage devices. If a media group contains tape media and NetVault SmartDisk devices, NetVault always uses the physical or virtual tape media from that group. To write backups to a NetVault SmartDisk device, you must explicitly select the device.
