Cloud Drive Sync : Sync Gateway Mode : What Happens to Simultaneous File Changes?
  
What Happens to Simultaneous File Changes?
With sync gateway mode, different people can work on the same files at the same time, which means that conflicts can occur. CTERA keeps track of who is making updates and when, detects file conflicts when updates occur simultaneously, and resolves those conflicts.
CTERA records the history of file events. The changes made in the most recent update are always saved to the original file. Changes that are lost due to conflict are retained in a renamed version of the file.
Note: In order for conflict resolution to be performed correctly, your cloud storage gateway clock must be synchronized with the CTERA Portal clock. If there is more than one hour difference between the two clocks (after taking into account time zone differences), the cloud storage gateway will not synchronize the cloud drive folder.
