Introduction to Synk

Synk is a file synchronizer. It automates the process of taking two folders full of files, deciding which version is the most recent version, and updating the older version of the file to be the same as the newer one. While there are many other features in Synk, they’re all in support of this basic compare-and-update functionality.

When a synchronization is happening in only one direction, that’s a backup. It’s the same underlying synchronization mechanism—checking for updated files and copying them to the other side—it’s just that only the source of the backup has changed files, and only the destination of the backup receives them.

Copying only changed files is dramatically faster than copying the entire folder again, and more importantly supports the case where file A is edited in one place and file B is edited in another, so just copying the whole folder in either direction would lose one of those changes.

Automating the synchronization process also means that you don’t have to remember what files you’ve edited where. Synk figures it all out for you and reduces the chance that you’ll forget about something and lose data.
