Here’s the problem. To get them to sync seamlessly and easily we have to use the cloud; whether iCloud or Google Drive or OneDrive or Box or whatever. Isn’t there a simple way to sync files between devices without stopping to rest in the cloud first?
BitTorrent Sync sends files from one device to another without a middleman so your files stay secure on your devices. Select the files to sync, select the devices to sync, and, well, done. All the work of synchronizing is handled in the background.
What’s the catch?
Well, there’s not one really. BitTorrent Sync requires the app to be on each device, of course, but the app is available for Mac, Windows, iOS App Store, and even Google Play for Android devices (and a variety of Unix and Linux versions).
The files on your Mac are transferred as encrypted files. Those files are never stored in the cloud somewhere, waiting for hackers to take what belongs to you. BitTorrent Sync works well with very large files, and there’s an option to share files, photos, video clips or whatever with others (kind of like the Dropbox public folder).
If you’re a bit paranoid about storing incriminating or valuable files or photos anywhere on the cloud, but you need them backed up and synchronized between devices, BitTorrent Sync does that. Better yet. It’s free.
What the app does not do is sync files on your Mac from one disk to another. Mac to Mac, yes. That’s the only caveat and that’s not the intended purpose of BitTorrent Sync anyway.
