• Question 137:

  Alter a SnapRestore reversion of a volume, incremental backup and restore operations on the file or volume cannot rely on the timestamps to determine what data needs to be backed up or restored. Which one of the following is the most likely course of action to take to ensure correct incremental backups?

  A. Perform a base-level backup of the volume after you restore it.

  B. Reboot the storage appliance to reset timestamps back to their original times before the reversion.
