Media Pools Without the Media Maximization option, each job requires its own set of tapes. Among these tapes, only the ones that include data from the same Backup Method can be shared: ■ Monday = Three full backup tapes. One tape for job1(day 1), one tape for job 2(day 1), and one tape for job 3(day 1) ■ Tuesday, Wednesday, Thursday = Three incremental backup tapes. One tape for job1(days 2, 3, and 4), one tape for job 2(days 2, 3, and 4), and one tape for job 3(days 2,3, and4). ■ Friday = Three weekly backup tapes. One tape for job1(day 5), one tape for job 2(day 5), and one tape for job 3(day 5). This results in nine tapes for the week. Note: If you submit a GFS Rotation job with Append Media enabled and BrightStor ARCserve Backup cannot use the previous day's media for some reason, it will format a media in the Scratch Set or a blank media using the "With Append Media" naming convention. To minimize the likelihood of this situation occurring, see Rules for Media Maximization in this chapter. Rules for Overlapping Media Because the Media Maximization option allows multiple GFS jobs using the same media pool to share tapes, you may encounter a situation where a media is busy because it is being used by another GFS job. If this occurs when submitting a GFS backup job without Append Media enabled, the job waits for the tape to become available before appending. The default wait time is 10 minutes. If the media is still busy after 10 minutes, the job uses another tape. If this occurs when submitting a GFS backup job with Append Media enabled, BrightStor ARCserve Backup tries to append to a previous day's media. If that media is busy, it waits 10 minutes. If the media is still busy after 10 minutes, the job uses the current date to generate another media and attempts to use it. If the new media is busy, the job waits 10 minutes. If this media is still busy after 10 minutes, the job formats another media with a new name. Note: You can change the wait time by entering a new value for the Windows registry key GFSwaittime. This registry key is located in HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\ BrightStor ARCserve Backup\Base\Task\Backup. Managing Devices and Media 7-19
