ca_backup Option -firsttapeopt -spantapeopt -firsttapetimeout Description Specifies media options for the first media used in the backup job. By default, this option is set to Append to Media. Note the distinction between a Blank media and Any media. Any media is formatted media which does not have the same media name as was provided in the job. The media selection search order is from left to right; therefore, if option owritesameblankany is specified, BrightStor ARCserve Backup first searches for a media with the same name as provided in the job and if it is found and is usable, the media is formatted using the same name and is used for the backup. If the same media name is not found, BrightStor ARCserve Backup will then search for a Blank media to use and if a Blank media is not available, BrightStor ARCserve Backup will then search for Any usable media to format and use for the backup. Specifies media options for any span media used in the backup job. By default, this option is set to Overwrite same or Blank. During spanning of media, if the option 'writesameblank is specified, then BrightStor ARCserve Backup first searches for a media with the same name and a higher sequence than the original media and if media is found and is usable, the media is formatted and used as the next sequence media. If a usable media is not found, then BrightStor ARCserve Backup will next search for a Blank media to use. Specifies the time in minutes to wait for a usable media to be made available for the backup job. By default, this value is 5 minutes. If a usable media is not made available within this time period, the job will time out and fail. Command Line Utilities B-17
