Symantec Backup Exec

Media or Resource

Displays a list of media that is required for the duplicate job, or the name of the resource that you selected to duplicate.

Media Location

Displays the location of the media. If the media is listed as Offline or Unknown, you must select a device in the Restore Device or Media Server column. Then place the media in a device that the managed media server can access.

If the data that is selected resides in a media vault, then Offline appears.

If the data that is selected for duplication resides in an unknown media location, then Unknown appears. The media cannot be found in any compatible storage devices that are candidates to run the job.

Device

Backup Exec creates a separate selection list and a separate duplicate job for every device.

Media set

Specifies the media set for the duplicate backup. If you select Overwrite, the media in the drive is overwritten if the media is scratch, or if its overwrite protection period has expired. If allocated or imported media are in the drive, they may also be overwritten depending on the Media Overwrite Protection Level that is set.

If you selected one of the append options, the backup will be added to an appendable media (if one exists).

Overwrite media

Places this duplicate backup on an overwritable media. Make sure that appropriate media is in the stand-alone drive or drive pool you select in the Device field in this dialog box.

The media in the drive is overwritten if the media is scratch or recyclable (its overwrite protection period has expired). If allocated or imported media are in the drive, they may also be overwritten depending on the Media Overwrite Protection Level that is set.

Depending on your configuration, overwritable media is selected from scratch media or recyclable media.

See How Backup Exec searches for overwritable media.

If the media in the drive is not overwritable, an alert appears requesting that you insert overwritable media.

Append to media, overwrite if no appendable media is available

Appends this duplicate backup to the media set listed in the Media Set field in this dialog box. The duplicate backup set is appended if an appendable media is available in the selected media set; if not, an overwritable media is used and added to the media set.

If an append job fills a media, the job continues on another piece of overwritable media.

If the media in the drive is not overwritable, an alert appears requesting that you insert overwritable media.

Append to media, terminate job if no appendable media is available

Appends this duplicate backup to the media set listed in the Media Set field in this dialog box. The duplicate backup set is appended if an appendable media is available in the selected media set; if not, the job is terminated.

Eject media after job completes

Ejects the media in the drive when the operation completes.

Retension media before backup

Runs the tape in the drive from beginning to end at a fast speed, which helps the tape wind evenly and run more smoothly past the tape drive heads. Retensioning is primarily for Mini Cartridge and quarter-inch cartridges and is not supported on most other types of tape drives.

Use Write once, read many (WORM) media

Specifies the use of WORM (write once, read many) media for this backup job. Backup Exec confirms that the destination device is or contains a WORM-compatible drive, and that the WORM media is available in the drive. If WORM media or a WORM-compatible drive is not found, an alert is sent.

See About WORM media.

Enable DirectCopy to tape

Enables data to be copied from a virtual tape library directly to a physical device. The Backup Exec media server records information about the data in the catalog. Because the information about the copied data is in the catalog, you can restore data from either the virtual device or the physical device.
