Multi-platform sync program - suggestions?

Hello NBR members,

I'm currently using a Windows 7 desktop and a MacBook Pro running Mac OS X. Presently, I use Windows Live Mesh (formerly called Live Sync) to synchronize my personal files (about ~20GB of pictures, documents) over a Hotmail account, but I'd like to complicate things by installing Ubuntu on the desktop and finding a way to sync between all these platforms. The problem is that Live Mesh is for Windows/Mac only. You should also know that the desktop and laptop do connect with each other over a local network almost daily. I also don't mind paying for a commercial solution as long as its good quality, so here are my core requirements:

- multiplatform (Win/Mac/Linux), 64-bit version for Windows 7
- synchronization via internet account AND/OR local network
- the program should run in the background and be unintrusive
- the data being synced can be substantial; I have 17GB of photos and ~3GB of documents. However I am willing to compromise by not having the photos synced if there are bandwidth limitations.

I'm open to suggestions! Keep 'em coming!

PowerFolder it's not on the list though you'll probably need the Pro version which is quite expensive.

 

Thanks ATG, I will consider PowerFolder as a potential solution.

 

rsync is an option. It's more of a *nix command-line utility, which should be ok for OS X too. For Windows, you can run it under cygwin, or you can try one of the Windows ports (which I haven't tried myself).

 

Unison is basically rsync with GUI and there is Mac and Windows versions too.

 

I use this: Super Flexible File Synchronizer

It works for me. The linux version is free. I haven't used the linux version so I can't comment on it's usability.

This software has great tech support.

 

Thanks guys, I will try all these programs to see which is best for my needs. Thanks again!
