An upgrade of the CATV system on campus continues this week.
Copy data management (CDM) is an approach to reducing storage consumption that involves eliminating the unnecessary duplication of production data.
Backup software and other enterprise applications operate independently, often creating multiple copies of the same data. Redundant copies of the same data, however, can waste storage space, slow down network performance and make accessing or restoring mission-critical data more difficult. CDM software can help eliminate those problems by reducing the number of full copies.
Most CDM software works by creating just one full copy of the data. When unique changes are made to the production environment, the software creates and stores a snapshot of incremental changes at the block level. The snapshot mechanism creates a read/write differencing disk with a parent-child relationship to the backup copy without creating an entire new copy. Because write operations are not directed to the backup copy, administrators do not have to worry about the contents of the primary backup being changed by accident. Reducing the number of full copies also reduces the chance of server sprawl and has a positive effect on costs, because valuable storage space is not taken up with unnecessary copies of data.
The phrase copy data management was made popular by storage vendor Actifio. Actifio captures production data, keeps a golden master current and spawns unlimited virtual copies for use whenever a copy of production data is needed. In a development, analytics or test environment, this approach is especially important; it means that the development, analytics or test environment can be based on an exact replica of the organization's production data without unnecessarily consuming storage space before it is needed.
