What Is Cloud Drive One Way Sync?

One-way sync: Replication will occur from one main cloud service to a secondary account, but if files are added or revised in the secondary account, the changes will not be reflected back to the original account. (By Wikipedia)

To make it simple, one way cloud drive sync is to sync files/folders, photos/pictures, videos/movies, documents/sheets, etc. data from one cloud storage (source location) to another cloud storage (destination). Any changes happen to source files like adding new contents, deleting waste items, adjusting incorrect descriptions and so on will trigger one way sync and duplicate changes to destination files. Yet, changes made to destination files will not be synchronized back to source ones. That is to say, the source will influence the destination while the destination won’t affect the source.

Tips: Two-way sync - All file additions and revisions made in the main account will be replicated to the secondary account. All file additions and revisions made in the secondary account will be replicated back to the main account. This creates an exact copy of data in both cloud accounts.
