Tape Backup Software
You need backup software that supports the Dell PowerVault 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. It is recommend that you use
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 the Dell
support website at
support.dell.com or visit the support site of your backup software
vendor.
