Chapter 13: Database Administration – Microsoft SQL ServerInitializing Backup Tapes4eInitializing the tape writes a label on the tape header. This label is the same as the physicallabel of the tape (for example, CD26S).The tape label and the expiration date are additional safety levels to prevent backing up tothe wrong tape, and possibly, destroying needed data. When using the DBA PlanningCalendar (DB13) for backups, the tape must be properly labeled to execute a backup to tape,because the transaction expects a specific tape to be in the drive. If the tape label does notmatch the required label, the backup will fail.Initializing and labeling is an option when executing the backup using DB13, SQL ServerEnterprise Manager, or NT Backup. (For SQL Server, see SAP note 141118 for a descriptionof the tape label naming convention used by DB13).13–18Release 4.6A/B
