Tape Backup Software

You need backup software that supports the DELL PowerVault LTO4-120 tape drive. As a general rule, native backup applications (such as NTBackup and tar)
do not provide the required data streaming rate to get the full performance of your tape drive. We recommend using a backup application that provides better
memory management as well as other useful features, such as TapeAlert. For the latest supported software versions, go to
support site of your backup software vendor.

the drive is running a cleaning tape. The
status light also flashes green if the tape
drive contains a cartridge during the
power-on cycle. In this case, the drive
completes POST and slowly rewinds the
