What happens to a volume when a Snapshot copy is reverted in NetApp Cloud Volumes Service for AWS?

When a Snapshot copy is reverted in NetApp Cloud Volumes Service for AWS, the state of the volume is restored to exactly how it was at the time the Snapshot was taken. This means that the contents of the volume become identical to the data stored in the Snapshot copy. Essentially, the revert operation effectively overwrites the current state of the volume with the data from the Snapshot, thus discarding any changes made after the Snapshot was created.

This process is crucial for data recovery scenarios where it is necessary to restore a volume to a previous state due to data corruption, accidental deletions, or other issues. The reverting operation does not retain previous modifications post-Snapshot; instead, it ensures that the volume reflects the state of the data precisely as it was at the time of the Snapshot.

In contrast, rerouting other options highlights different functionalities that do not occur during a revert operation. For instance, clients do not need to remount the volume (as stated in one of the alternatives), and the Snapshot copy policy remains unchanged after a revert, confirming that the revert action itself focuses solely on restoring data rather than altering the policy settings.
