It automates the accuracy of storage management functions including data backup, migration of backup data to off-site storage, data archiving and retrieval, disk space management and recovery from server failures. Resides on both mainframes and servers involved in the backup process and uses a data compression technique called binary object technology to conserve space on local magnetic disk units and decrease the amount of data being sent over a network. It also uses existing LAN servers to back up data, creating hot spares that allow rapid rebulding and restoration of damaged files. Additionally, access to backup or archived files is limited to users with current access to active copies of these files.
Administrators can limit the locations from which files can be accessed.
Also provides automatic dual backup for added security and central administration with local override. High-performance local backup is required to keep pace with the recent explosion in database sizes. Mainstream online transaction processing and data warehousing applications are nearing terabyte volumes. NetWorker V4.3 implements a new high-performance architecture designed to meet the scalability and availability requirements of modern database applications. The EMC Data Manager system provides industry-leading performance and functionality in a complete, integrated software and hardware solution specifically tailored for very large database tape backup and restore environments.
