Which method helps in ensuring data integrity and availability in storage virtualization?

Data mirroring is a technique used in storage virtualization that ensures both data integrity and availability. It involves creating an exact copy of data from one location to another in real-time. This method not only protects against data loss due to hardware failure or corruption but also maintains data integrity by ensuring that the mirrored data is an accurate reflection of the original data at any given moment. If the primary data source becomes compromised or unavailable, the mirrored copy can be accessed, preserving the continuity of operations.

This method is particularly effective in environments where uptime is critical, as it allows for quick recovery without data loss. Because data mirroring continuously synchronizes the original and mirrored copies, any changes made to the data are reflected immediately, further ensuring that the data integrity is upheld.

The other methods, while beneficial in certain contexts, do not effectively serve the dual purpose of ensuring both integrity and availability to the same extent as data mirroring. Data archiving allows for long-term storage but doesn’t focus on immediate availability. Data replication, although it provides additional copies of data for redundancy, may not always synchronize in real-time, which could lead to discrepancies in data integrity. Data compressing, while useful for saving space, does not contribute directly to data integrity or availability in the way
