Arcserve Backup lets you specify the following general options:
The Global Scratch Set treats all of the scratch tapes in all media pools as one large Scratch Set. This helps ensure that backup jobs do not fail when a scratch tape is not available in its own media pool.
When this option is enabled, the Media Pool Manager shows only the Save Set for each pool (not the Scratch Set), but adds an object named GlobalScratchSet. This object contains all of the media available in the scratch sets of all your media pools. If you right-click GlobalScratchSet and select Assign Media, you can move media from an unassigned set to the Scratch Set.
When you select a media in the Global Scratch Set, two extra properties appear as column headings on the top right-hand pane and on the Properties tab in the lower right hand pane: Medium Type and Media Pool. If you click a column heading on the top right-hand pane, you can sort the list by that column. If the media you select in the Global Scratch Set is vaulted, it appears in a different color to indicate that it is inactive.
Note: If you enable the Global Scratch Set and submit a backup job using a specific media pool, Arcserve Backup first attempts to find media in that media pool's Scratch Set. If no media is available, the Global Scratch Set media will be used. Also, if you specify a media pool and submit a backup job that spans tapes, media in the Global Scratch Set can be used.
Note: This option is available only on Windows computers.
