What is it?
Syncplicity is a cloud-based file storage system designed to back up, store and sync your files.  Syncplicity LLC has both personal and business solutions with an eye toward security, flexibility and seamless ease.

How it works?
Install Syncplicity onto your computer by signing up on the website and going through the process.  When the program is installed it stays active on your computer, and the chosen files will sync between the devices you register on Syncplicity.

The Basics:
For the personal edition there are two editions: free and personal.  The Free Edition is actually a pretty good deal with:
  • 2 GB of storage
  • syncs between up to 2 computers and mobile devices
  • unlimited files and folders
  • works with PC, Mac, iPhone, iPad, Android and Google Docs
  • community support forums

The Personal of course is a better deal and well worth the money especially if you've got a lot to store:
  • $15 per month
  • 50 GB of storage
  • syncs between up to 5 computers and mobile devices
  • unlimited files and folders of any file size
  • works with PC, Mac, iPhone, iPad, Android and Google Docs
  • priority support
The Business Edition is a free 30-day trial with various options after the trial, depending on what suits your business needs.  You can see the full comparison here.

The Pros:
Syncplicity is really easy to use and really seamless.  It's very easy to switch it to a new computer if you're upgrading, add or subtract a device.  The 2GB of space is plenty for backing up writings and Syncplicity automatically re-syncs when a file in the designated folder changes.  Once it's installed there really isn't any kind of further user effort to keep your stuff updated or to make sure the program does its' job.  It works quite well on its own, it's very seamless.

The Cons:
I can't really think of any cons.  The business edition looks pretty customizable, the personal edition looks plentiful enough for the average user, it doesn't even take up much memory in the background.  If you have memory issues where you can't have too many programs running in the background at once you may have to manually turn it on and off to back up your files.  It's not one of those programs where the free version makes you wish it was a little jucier while not making the paid version worthless.

My Thoughts:
I love it.  I love that it's so seamless, I love that I don't have to fuss with it much and I love how easy it is to use.  When I got my new computer and had to bring Syncplicity onto my new machine I had no issues.  Everything syncs, well seamlessly just like it's supposed to.  Plus I like that if it has a hard time connecting to the server or if I go offline and a file changes it keeps the updates and immediately sends the update to the server as soon as connection is re-established.  I can't recommend it enough, it's a great addition to your back-up plan.
