Data Protection: Adapting To The Sea Change (VI)

Focusing on high availability and neglecting the other key objectives of data protection is dangerous.

Too often high availability and data protection are considered synonymous. Data availability is only one of four key objectives for data protection — data preservation, data responsiveness, and data confidentiality are the others. An overemphasis on high availability could lead to underweighting the other objectives.

If the necessary amount of data preservation is not in place, high availability of an application will not matter. If the correct controls for data confidentiality are not in place, serious consequences could result. If data responsiveness is not in place, data will not be usable. A sense that all the objectives have to be balanced properly is necessary.

This report “Data Protection: Adapting to the Sea Change” enables IT managers re-examine and improve their overall data protection strategy. By placing data protection in the context of broader business aims, this report allows IT managers to better determine what their data protection requirements are, and the types of data protection technologies that can best fulfil those requirements.

The key insight of this report is that IT organizations can examine their overall data protection strategy in terms of a data protection “framework.” Using a framework allows the reader to understand the key interrelationships between normally separate processes, and to apply the right mix of existing (e.g., tape automation) and emerging (disk-based backup, continuous data protection, dated replication, and MAID) technologies to avoid fixes in one area that make matters worse in another.
