What is the method for restoring a history block in Historian Server?

Restoring a history block in Historian Server involves the method of copying the associated folder back to the history storage path. This process is essential because each history block corresponds to a specific folder that contains the relevant archived data files. When a history block is lost or becomes corrupted, bringing back the folder from a backup allows the system to reintegrate the data seamlessly into the server.

This approach preserves the integrity of the data structure and ensures that all related metadata and configuration settings associated with the history block are restored correctly, thereby minimizing potential issues that can arise from improper restoration techniques. The other methods are not suitable for this purpose because they do not directly facilitate the accurate recovery of historical data in the required format.
