I have a directory I want to sync over the cloud using a service like Dropbox. But, within that folder, I only want to sync directories that match a particular pattern.

For instance, sync all folders except folders named node_modules.

Do you know of any way to do this? Here are some ideas I had, and their pitfalls:

  1. Using any sync service, say, Dropbox, set up an AppleScript to watch changes in some directory on my computer. If the change is not in node_modules, push it over to the Dropbox folder location. Issues: Does not have two-way sync.

  2. Solve the issue of #1 by utilizing rsync in some clever way. Issues: Race condition handling? I'm worried about two computers modifying the same file within too short a time frame, and rsync freaking out.

Have you dealt with this issue before? What's your solution?

To clarify, this isn't about excluding a single, or even a finite number of directories. I want to exclude any and all directories/files that match a given pattern, wherever they may be in the folder. So I might have 1000 node_modules directories within my synced directory, and they are all excluded.

6 - Confirm that changes will work (Created a test folder to try out rules)

Enjoy!

  • This is the sketchiest looking software I've ever seen. But it just might work. I'll take a closer look at it over the weekend. I really appreciate the thoroughness with which you responded – thanks for that. Awww shucks, Windows only! I'm on OSX. But I'm glad to see that solutions do exist... – jamesplease Dec 19 '13 at 23:33
  • Np. It's a shame it work for you, hopefully for someone else though. – riseagainst Dec 19 '13 at 23:49
