EMC Corporation today announced enhancements to EMC (R) Data Manager (EDM(TM)) backup and restore solution for open systems.
According to EMC, enhancements include the ability to perform simultaneous NFS (UNIX) and CIFS (Windows NT) backups, while maintaining all of EDM’s rich backup and restore functionality, and the ability to choose the highest-performance path – either NAS or SAN — for specific file backups. This feature is achieved through EDM support for EMC Celerra(TM) HighRoad(TM) software, InfoWorld Magazine’s Storage Product of the Year.
EMC says its EDM bi-lingual support, enabling customers to backup and restore both NFS (UNIX) and CIFS (Windows ) files as a single operation, preserves the specific file attributes associated with the various data types on today’s files servers.
Support for EMC Celerra HighRoad software, EMC says, enables EDM to determine the optimal route for data delivery – either NAS or SAN. This feature bypasses the local-area network to move large NFS and CIFS files directly from NAS-attached EMC Symmetrix (R) Enterprise Storage systems over a high-speed Fibre Channel SAN to an EDM-managed tape device. EDM with HighRoad support offloads both file server CPU and network demands, offering increased performance for backup and recovery for large Celerra-based files when compared with local or network backup options.
According to EMC, this channel-based backup method also allows multiple EMC Celerra systems to perform high-speed backup to a shared centralized tape library, therefore eliminating the need for dedicated backup resources for each NAS device and lowering the cost of backup and restore in large environments.
