NetVault 13.0 - Administration Guide for Managed Service Providers

On the NetVault Server Settings page, under Services, click Media Manager. In the Media Manager dialog box, under Media Request Weightings, configure the following settings.

Table 141. Media request weightings
Setting	Description
Local Device Weighting	The media request weighting for local devices is set to 32 by default. To change this setting, type or select the new value. You can assign any value between 2 and 32.
RAS Device Weighting	The media request weighting for RAS devices is set to 16 by default. To change this setting, type or select the new value. You can assign any value between 2 and 32.
Non NDMP Device Weighting	The media request weighting for non-NDMP devices is set to 8 by default. To change the default setting, type or select the new value. You can assign any value between 2 and 32.
Media Loaded Weighting	The media request weighting for media-loaded devices is set to 4 by default. To change the default setting, type or select the new value. You can assign any value between 2 and 32.
Device Empty Loaded Weighting	The media request weighting for empty loaded devices is set to 2 by default. To change the default setting, type or select the new value. You can assign any value between 2 and 32.

By default, the Media Manager gives preference to a local device. To use any other suitable device for a job, you can set a higher media request weight for that device. For example, to ensure that the Verification phase for a job uses the same NDMP device that was used for the backup, you can set a higher value for the Media Loaded Weighting option. If you use the default media request weights, the Media Manager gives preference to a local device even if the required piece of media is loaded into the NDMP device.

Click Apply to apply the new settings and close the dialog box.

Configuring default interval for backup retirement scans

In time-based retirement, the time component (HH:MM) does not represent the actual retirement time. This component only represents the time due for backup retirement. The actual time of retirement is determined by the interval at which Media Manager scans the Media Database to identify the backups that it needs to retire. The default interval between two scans is 60 minutes. Thus, if the retirement time is set to 10:20, the backup is actually retired at 11:00.

You can change the default interval for backup retirement scans in the mediamgr.cfg file.

To configure the default interval for backup retirement scans:

Open the mediamgr.cfg file in a text editor. You can find this file in the config directory under the NetVault installation directory.

Add the following lines:

[Defaults:Retirement Check Granularity in Mins]

Value = <Minutes>

By default, the mediamgr.cfg file does not include the [Defaults:Retirement Check Granularity in Mins] section. To change the default interval, you must add this section and specify the interval. If you do not add the section, the default interval (60 minutes) is used.

For example, to set the scan interval to 30 minutes, add the following lines:

[Defaults:Retirement Check Granularity in Mins]

Value = 30


	NOTE: If you set this value to 0 (zero), the savesets are retired according to the time specified in the Advanced Options set or the Change Expiry dialog box.
