About OpenStorage direct to tape
OpenStorage direct to tape lets you copy NetBackup backup images directly from a disk appliance to tape. The copy operation does not use NetBackup media server I/O.
NetBackup manages the copied images based on retention periods you define.
Direct to tape uses the Network Data Management Protocol (NDMP) for the copy operations. Direct to tape requires specific NDMP features and release levels.
