NSR Stage

The NSR Stage resource describes the staging policy used by a Backup server.To edit the NSR Stage resources for a Backup server use "nsradmin " or "nwadmin".

The NSR stage resource has the following attributes:

• The name attribute specifies the staging policy name.

• The enabled attribute specifies whether or not save sets are automatically staged from devices associated with a policy. It also enables and disables the periodic recover space operations.

• The max storage period attribute specifies the maximum number of days for a save set in a given volume before it is staged to a different volume.

• The high water mark % attribute specifies the point at which save sets should be staged, measured as the percentage of available space used on the file system. Staging will continue until the lower mark is reached.

• The low water mark attribute specifies the point at which the staging process should stop, measured as the percentage of available space used on the file system.

• The Save set selection attribute specifies the save set selection criteria for staging. It may be one of four values:

  • largest save set

  • smallest save set

  • oldest save set

  • youngest save set.

• The Destination pool attribute specifies the pool save sets should be sent.

• The Devices attribute specifies the file type devices are associated with.

• The Recover space interval attribute specifies the number of hours between recover space operations for save sets with no entries in the media database form file devices.

• The Fs check interval attribute specifies the number of hours between file system check operations.

• The Start now attribute specifies the selected operation to be triggered immediately on all devices associated with a policy. Operation can be one of the following:

  • Check fs, check file system and stage data if necessary.

  • Recover space, recover space for save sets with no entries in the media database.

  • Stage all save sets, stage all save sets to the destination pool.

    Following is an example of a NSR Stage resource:

    type: NSR stage; name: test stage1; autostart: Enabled; max storage period: 7; high water mark (%): 90; low water mark (%): 85; save set selection: largest save set; destination pool: Default Clone; devices:h:\disk\fd0; start now: ;
