Media that meets or exceeds the discard thresholds determined by the media manufacturer should be associated with the Retired Media media set. Based on a measurement of soft errors generated by the storage device firmware, media that exceeds acceptable levels of these errors are reported to Backup Exec as potential candidates to be discarded.
Associate any media with an unacceptable level of errors to Retired Media so that you are protected against using defective media before critical backup operations begin. After you mark media as retired, it will not be used by Backup Exec for future backup jobs. The media is still available to be restored from if it is not damaged.
