Disk Staging Schedule dialog box
Click to display the Disk Staging Schedule dialog box. The dialog box is similar to the scheduling dialog box that appears when a policy is configured.
The schedule that is created for the disk staging storage unit is not listed under Schedules in the NetBackup Administration Console when the Policies utility is selected.
Figure: Disk Staging Schedule for a basic disk staging storage unit shows the disk staging schedule for a basic disk staging storage unit.
The Attributes tab on the Disk Staging Schedule dialog box differs from the Attributes tab of a regular policy. The differences are described in the following table.
Table: The Attributes tab settings
| Attribute | Description |
|---|
|
Name
|
The Name on the Disk Staging Schedule dialog box automatically 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.
See Default Job Priorities properties.

|
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.
See Retention Periods properties.
See Frequency (schedule attribute).

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.
The relocation schedule that was created for the basic disk staging storage unit is not listed under Schedules in the NetBackup Administration Console when the Policies utility is selected. |
|
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:
Any lets NetBackup choose the media owner. NetBackup chooses a media server or a server group (if one is configured).
None specifies that the media server that writes the image to the media owns the media. No media server is specified explicitly, but you want a media server to own the media. A server group. A server group allows only those servers in the group to write to the media on which backup images for this policy are written. All server groups that are configured in the NetBackup environment appear in the drop-down list.

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 execute 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.
