Which resource can be used to identify the configuration of the primary backup system?

HP Tape Assure is a proactive monitoring and analytics service focused on health trends and predictive alerts, not on identifying the current configuration of a backup system.

HP D2D Storage Sizer is a capacity and performance sizing tool used to plan new disk-to-disk backup deployments, not to report on or identify an existing system's configuration.

HP Library and Tape Tools (LTT) is a standalone diagnostic and configuration utility that communicates directly with HP tape drives and libraries to report device configuration, firmware levels, and operational status. It is the primary resource for identifying how an existing tape-based backup system is configured, requiring no additional management infrastructure. LTT supports identification and diagnostic tasks across a broad range of HP and OEM tape products.

HP D2D Support Ticket is a support case submission mechanism, not a tool or resource for identifying backup system configuration.
