Hardware ComponentsThe hardware listed in the table below is to backup and restore the database andtransaction logs:System NameBackup HardwareDEV 1 x DLT 7000 35/70 GB, 1 DDS-3 12/24QAS 1 x DLT 7000 35/70 GB, 1 DDS-3 12/24PRD 2 x DLT 7000 35/70 GB, 2 DDS-3 12/24To easily retrieve tapes from storage, you need to track and document them.The issues are: Labeling Tracking Handling Retention requirementTapes should be clearly labeled using one of many labeling methods. Three simple methodsare described in the examples below. Two of these methods are used by R/3 and areimportant if you use DB13 to schedule your backups. Third-party backup managementsoftware may assign their own tracking number for the labels. In this case, you must use thelabel specified by the software.System Administration Made Easy3–13
