You can specify the overwrite/append rules for the media used in your backup job while you are configuring the job.
The following types of options are available:
First Media Options
The first media is the media you use when the backup job begins. The options for the first media are:
Append to Media
Append job sessions to the selected media.
Overwrite Same Media Name, or Blank Media
Overwrite the media in the drive only if it is the one you specified for the job or if the media is blank. If neither of these conditions is met, Arcserve Backup prompts you to supply the specific media name.
Overwrite Same Media Name or Blank Media First, then Any Media
Overwrite any media found in the drive. If you select this media option, Arcserve Backup checks to see if the media in the drive is the one specified for the job. If it isn't, Arcserve Backup checks to see if the media is blank. If the media isn't blank either, Arcserve Backup reformats whatever media it finds in the device and starts backing up files at the beginning of the media.
Timeout for First Media
Number of minutes Arcserve Backup spends attempting to write to media before canceling job.
Additional Media Options
These options apply to jobs that require more than one media. You need to specify which media Arcserve Backup can use when the job spans media.
Overwrite Same Media Name, or Blank Media
Write to the media in the device only if it has the same media name (but a different media ID) or if it is blank. Arcserve Backup remembers the name and ID of the job's first media. When the job requires an additional media, Arcserve Backup checks if the new media has the same name (but different media ID) or if it is a blank media. As long as the ID is different, Arcserve Backup reformats the media, giving it the same name and ID as the first media. The sequence number changes.
Overwrite Same Media Name or Blank Media First, then Any Media
Overwrite any media found in the device (as long as it has a different ID from the first media's ID). All subsequent media are reformatted with the same name and ID as the first media. Only the sequence number changes.
Timeout for Additional Media
Number of minutes Arcserve Backup spends attempting to write to media before canceling job.
