About Dropbox one way sync

Dropbox is one of the mainstream cloud storage services, and users are used to storing files in remote locations and syncing files. As one of the most useful features of Dropbox, file sync is actually the process of ensuring that the same files are contained in different locations. So what is Dropbox one way sync?

one-way sync vs. two-way sync

The most common types of file sync are one-way sync and two-way sync. As long as the device is connected to the network normally, all selected files and edits to files will be synced to another place.

One-way sync is a sync project that only involves one direction. Files will be transferred from the source location to the target without transferring any files back. For Dropbox one way to sync on Mac and Windows PC, it can be to sync files from the local to Dropbox to store data, it can also be to sync files from the Dropbox cloud to the local, or to sync files from Dropbox to another cloud drive.

Two-way sync is a two-way copy of files so that the two locations are synced with each other. In this type of sync, changes made at the source or target location will be reflected in both directions.

There are many cloud storage services on the market, and several mainstream services such as Google Drive, OneDrive, and iCloud have their own characteristics. You may make Dropbox sync one way to another cloud or vice versa for one of the following reasons:

  • There is not enough storage in your Dropbox account, you need to migrate Dropbox to another cloud drive with more storage to get more space.
