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, 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 value is stored in the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\Arcserve Backup\Base\Task\Backup
