General Server properties
The properties apply to selected master and media servers.
The General Server dialog box contains the following properties.
Table: General Server dialog box properties
Property | Description |
|---|
Delay on multiplexed restores | This property specifies how long the server waits for additional restore requests of multiplexed images on the same tape. All of the restore requests that are received within the delay period are included in the same restore operation (one pass of the tape). The default is a delay of 30 seconds. |
Check the capacity of disk storage units every | This property applies to the disk storage units of 6.0 media servers only. Subsequent releases use internal methods to monitor disk space more frequently. |
Must use local drive | This property appears for master servers only, but applies to all media servers as well. This property does not apply to NDMP drives. If a client is also a media server or a master server and is checked, a local drive is used to back up the client. If all drives are down, another can be used. This property increases performance because backups are done locally rather than sent across the network. For example, in a SAN environment a storage unit can be created for each SAN media server. Then, the media server clients may be mixed with other clients in a policy that uses ANY AVAILABLE storage unit. When a backup starts for a client that is a SAN media server, the backups go to the SAN connected drives on that server. |
Use direct access recovery for NDMP restores | By default, NetBackup for NDMP is configured to use Direct Access Recovery (DAR) during NDMP restores. DAR can reduce the time it takes to restore files by allowing the NDMP host to position the tape to the exact location of the requested file(s). Only the data that is needed for those files is read. Clear this check box to disable DAR on all NDMP restores. Without DAR, NetBackup reads the entire backup image, even if only a single restore file is needed. |
Enable message-level cataloging when duplicating Exchange images that use Granular Recovery Technology | This option performs message-level cataloging when you duplicate Exchange backup images that use Granular Recovery Technology (GRT) from disk to tape. To perform duplication more quickly, you can disable this option. However, then users are not able to browse for individual items on the image that was duplicated to tape. See the NetBackup for Exchange Administrator's Guide. |
Media host override list | Specific servers can be specified in this list as servers to perform restores, regardless of where the files were backed up. (Both servers must be in the same master and media server cluster.) For example, if files were backed up on media server A, a restore request can be forced to use media server B. The following items describe situations in which the capability to specify servers is useful: Two (or more) servers share a robot and each have connected drives. A restore is requested while one of the servers is either temporarily unavailable or is busy doing backups. A media server was removed from the NetBackup configuration, and is no longer available.
