Introduction

A Robot Save move set is a sequence of locations that tape volume movement should follow. The move set documents a tape’s movement cycle from backup to storage and to backup again. Each list of locations (the move set sequence) is given a move set name. You can create as many move sets as you want. Each backup set can have its own move set, or can reference a common move set. See the Robot Save User Guide for a complete discussion of creating and using move sets.

Robot Save allows you to create three types of move sets, each using a different method to control the movement of volumes:

  • Manual: Volume movement occurs only if you select the option to move a rotation or individual volumes. Robot Save does not automatically move the volumes.

  • Maximum Days at Location: Robot Save automatically moves backup set rotations from one location to the next based on the number of calendar days allowed at each location. Volumes move automatically to the IN USE location when they are used in a backup. When the backup completes, the volumes in the rotation move to the next location in the move set. The volumes remain at each location for the specified number of days, then move to the next location the next time a save is run. You specify the number of days (including weekends) that the rotation remains at each location. A rotation becomes eligible to be moved after it has been at the location the specified number of days.

  • Maximum Rotations at Location: Robot Save automatically moves backup set rotations from one location to the next based on the number of rotations of a backup set allowed at each location. Volumes move automatically to the IN USE location when they are used in a backup. When the backup completes, the volumes move to the next location in the move set. The volumes remain at the location until the total number of rotations of the backup set at the location has been exceeded, then move to the next location.

Note: If you use a scratch pool location, volumes should not move to the scratch pool location until they expire. The sum of the maximum number of days in each location (except the scratch pool location) should be equal to or greater than the actual number of days before the media expires.

When a backup completes normally, the RBSAUTOMOV command runs automatically if an automatic move set is attached. This moves all volumes that are to be moved for that day. If you do not run daily backups or run backups that do not have automatic move sets, you can schedule the RBSAUTOMOV command to move volumes to the next location automatically. We recommend that you schedule the RBSAUTOMOV command to run daily in case your backups fail.

If any days are missed and the command is not run, the next backup with a move set performs a "catchup" move and moves the volumes to where they should be. You also can run the RBSAUTOMOV command to perform the catch up move. If a volume is moved to the scratch location after it has expired, the volume is removed from the rotation and released to the scratch pool automatically.

The following examples show setting up and using three different move sets that use Maximum Days at Location with Auto Move Set processing enabled (do this on the Media Defaults panel).

Notes:

  • You need to define storage locations for the volume movement before creating a move set.

  • The sum of the maximum number of days in each location (except the scratch pool location) should be equal to or greater than the actual number of days before the media expires.

Defining Move Sets

  1. Create the locations for the move sets. From the Robot Save Main Menu, select option 7, System Setup Menu. Then, on the System Setup Menu, select option 5, Storage Location Entry. When the Storage Location Entry panel displays, enter the name of each location you want to create on a blank line. When you press Enter, the names are sorted in alphabetical order.

    Notes:

    • The Scratch location must be on-site to allow your volumes to be released to the scratch pool.

    • Do not define an AML location using the Storage Location Entry panel. An AML location is defined when the AML is defined to Robot Save and does not display on this panel.

  2. Define the move sets you want to use for your backups. Each move set describes the sequence of locations used by the backup set volumes. From the System Setup Menu, select option 7, Move Set Maintenance. Press F6 to define each new move set.

Example One: Daily

The daily backup set has five rotations, one day until the next rotation, and four days before the media expires. The following panel shows how you might define the daily move set:

Example Two: Weekly

The weekly backup set has three rotations, seven days until the next rotation, and 14 days before the media expires. The following panel shows how you might define the weekly move set:

Example Three: Monthly

The monthly backup set has three rotations, 30 days until the next rotation, and 60 days before the media expires. The following panel shows how you might define the monthly move set:

Note: You also can move the volumes back on-site after they have expired. You can find additional information on creating and using move sets in the Robot Save User Guid.
