One way sync vs two way sync

The purpose of file synchronization is to make two or more destinations save the same, up-to-date, files, so that the files can be accessed at any time on different devices. However, synchronization can be “one-way” or “two-way”. One way sync (a.k.a mirroring) copies files from your source system to the target system in one direction. Two way sync (a.k.a bi-directional) copies files in both directions, from both systems. Undoubtedly, OneDrive one-way sync or two-way sync works both helpful in their working scenarios.
