Schedule settings for disk staging
The following settings are available when you create a disk staging schedule.
Table: The Attributes tab settings
Attribute | Description |
|---|---|
|
Name |
The schedule Name defaults to the name of the storage unit. |
|
Priority of relocation jobs started from this schedule |
The Priority of relocation jobs started from this schedule field indicates the priority that NetBackup assigns to relocation jobs for this policy. Range: 0 to 99999 (highest priority). The default value that is displayed is the value that is set in the Default job priorities host properties for the Staging job type. |
Creates multiple copies of backups. NetBackup can create up to four copies of a backup simultaneously. When this setting is enabled, Final destination volume pool and Final destination media ownership are disabled. | |
|
Final destination storage unit |
If the schedule is a relocation schedule, a Final destination storage unit must be indicated. (A relocation schedule is created as part of a basic disk staging storage unit configuration.) A Final destination storage unit is the name of the storage unit where the images reside after a relocation job copies them. To copy images to tape, NetBackup uses all of the drives available in the Final destination storage unit. However, the Maximum concurrent write drives setting for that storage unit must be set to reflect the number of drives. The setting determines how many duplication jobs can be launched to handle the relocation job. NetBackup continues to free space until the Low water mark is reached.

|
Final destination volume pool |
If the schedule is a relocation schedule, a Final destination volume pool must be indicated. (A relocation schedule is created as part of a basic disk staging storage unit configuration.) A Final destination volume pool is the volume pool where images are swept from the volume pool on the basic disk staging storage unit.
|
|
Final destination media owner |
If the schedule is a relocation schedule, a Final destination media owner must be indicated. (A relocation schedule is created as part of a basic disk staging storage unit configuration.) A Final destination media owner is the media owner where the images reside after a relocation job copies them. Specify one of the following:
|
|
|
Frequency If the backups that use a disk staging storage unit run more frequently than expected, compare the retention level 1 setting with the Frequency setting. Internally, NetBackup uses the retention level 1 setting for scheduling purposes with disk staging storage units. Make sure that the frequency period is set to make the backups occur more frequently than the retention level 1 setting indicates. (The default is two weeks.) For example, a frequency of one day and a retention level 1 of 2 weeks should work well. Retention levels are configured in the Retention periods host properties. |
|
Use alternate read server |
An alternate read server is a server allowed to read a backup image originally written by a different media server. The path to the disk or directory must be identical for each media server that is to access the disk. If the backup image is on tape, the media servers must share the same tape library or the operator must find the media. If the backup image is on a robot that is not shared or a standalone drive, the media must be moved to the new location. An administrator must move the media, inventory the media in the new robot, and run bpmedia -oldserver -newserver or assign a failover media server. To avoid sending data over the network during duplication, specify an alternate read server that meets the following conditions:
If the final destination storage unit is not connected to the alternate read server, data is sent over the network. |
| Specify the number of copies to create simultaneously. Range: 1 to 4. |
| Indicates the priority that NetBackup assigns to duplication jobs for this policy. Range: 0 to 99999 (highest priority). |
For each copy you want to create, select the copy settings. Copy 1 is the primary copy. If Copy 1 fails, the first successful copy is the primary copy. Specify the storage unit where each copy is stored. If a Media Manager storage unit has multiple drives, it can be used for both the source and the destination. Specify the volume pool where each copy is stored.
For tape media, specify who should own the media onto which NetBackup writes the images. These settings do not affect any images that reside on disk. One media server does not own the images that reside on shared disks. Any media server with access to the shared pool of disk can access the images.
