file synchronization (file sync)

File synchronization (file sync) is a method of keeping files that are stored in several different physical locations up to date. Cloud and storage vendors often offer software that helps with this process.

File synchronization has grown increasingly important as enterprises use the cloud as a means for collaboration. It is also commonly used for backup and for mobile access to files. However, file synching often presents security concerns to enterprises whose employees use consumer-grade applications to access business files.

File synchronization software is used to store copies of on-premises data to another device or to the cloud. The files are typically available to be accessed via a Web-based portal. Some examples of file sync software include Box, Syncplicity and Dropbox.
