One-way sync vs two-way sync
As you may know, file synchronization is the process of making sure that two or more locations contain the same, current files. Actually, file synchronization also has different types. The most common types are one-way sync and two-way sync.
To put it simply, one-way sync means that files are copied only from source to a target in one direction, but no files are ever copied back to the primary location. In a two-way type of sync, files get copied in both directions. Both locations get synchronized with each other. This way, in the event of a failure, you can still access your documents via another machine.
