Save Set Staging

Save set staging is a process of moving data from one storage medium to another and removing the data from its original location. If the data was on a file device type, the space is reclaimed so that the disk space can be used for other purposes. Use save set staging to move save sets that you have backed up, archived, or migrated. Staging is especially recommended for save sets that you backed up to a file device type to move the data to more permanent storage, such as an optical or tape volume.

You can configure policies in the Staging resource to have Backup perform automatic staging once criteria you set is reached. Or you can use the nsrstage program to perform staging manually.

When you issue the nsrstage command, Backup creates a clone of the save set you specify on a clone volume of the medium you specify. If you stored the save set on a file device type, Backup deletes the save set from its original location to free the space the save set occupied. Backup tracks the location of the save set in the media database. The retention policy for the save set does not change when the data is staged.

To stage a save set using the command line, enter the nsrstage command at the shell prompt. For example, to stage an individual save set, enter the following command:

# nsrstage -s server -b pool -m -S save-set-ID

Refer to the nsrstage(1m) man page for the syntax and options for the nsrstage program.

To set or change staging polices, use the nsradmin command, or use the Customize resource in the nwadmin GUI. Refer to the online help for more details about the Stage resource.
