The IBM ProtecTIER system is a backup to disk solution that performs deduplication and compression to improve storage efficiency. The system consists of two models to address different customer environments in open systems. There is also a mainframe (System z) model, the TS7680, that uses a FICON controller in front of a ProtecTIER server. As a backup target for open systems backup software, the ProtecTIER system can be configured as a Virtual Tape Library (VTL) emulating popular tape libraries and tape drives, as a NAS target communicating over CIFS or NFS protocol, or as an OST (OpenStorage Technology) controlled device from Symantec NetBackup.
