What is Bidirectional Sync
File synchronization (or syncing) in computing is the process of ensuring that computer files in two or more locations are updated via certain rules. It is often used for home backups on external hard drives or transfer updates on external hard drives to cloud. Before knowing about bidirectional synchronization, it’s necessary to know the one-way synchronization.
In One-way Sync mode, the updated files are copied from a source location to one or more target locations, any changes in your source location, like creation, deletion, modification, will be synced to the destination, but no files are copied back to the source location.
In Bidirectional Sync mode, also called two-way sync, the updated files are copied in both directions, usually with the purpose of keeping the two locations identical to each other. Any changes in the source path will be synchronized to the destination; any changes in the destination path will be synchronized to the source as well.
Benefits of Bidirectional Folder Syncing
Nowadays, as people need to store more and more data and files in life or work, the storages where they store data are also changing. For instance, many users back up files to different cloud storages in order to make files easily accessible no matter where they are or what device they are using. Other storage devices such as external hard drives, NAS, and USB flash drives are also commonly used.
At the same time, two-way folder synchronization has become one of the most popular backup modes with its outstanding advantages.
