Two-way data synchronization is a process of keeping two or more data sources in sync with each other. In a two-way sync, information is updated in both directions. This means that if the information is updated in the first location, then it will be automatically updated in the second location as well – and vice-versa1.

For example, if you have a file stored on your computer and you want to keep it up-to-date on your phone as well, you can use two-way data synchronization to ensure that any changes made to the file on your computer are automatically reflected on your phone, and vice versa. This can be useful for keeping data consistent across multiple devices or systems2.
