SugarSync hands down and with flying colors surpassed all of its competition and earns our "TopTenREVIEWS Gold Award." This is the only online data backup service that has compatibility with all the major smartphones; they even have a version that works with Android. It also provides nearly all of the basic backup features we were looking for and all of the sharing tools.
In addition, SugarSync has a unique tool called the Magic Briefcase that will let you sync and share selected data among multiple computers. You can even perform simple edits of files through the web; we have not seen this ability in any other online backup service. They also offer more sharing tools than most in all versions; most require a Pro upgrade to access advanced features.
SugarSync Standout Features:
SugarSync does just about everything; it has easy to use online, mobile and desktop interfaces that have the ability to perform automatic backups, manage folders, share folders, display a photo gallery, store mobile photos and more. To backup files you can simply drag and drop them into the desired folder and it can perform incremental syncs, which mean it will only backup changes in your files for fast backups.
It also supports archiving and versioning (up to 5 versions) and unlike most services it can sync between multiple computers without paying for an extra license. Anything that you want to share with other computers, including mobile devices, can be achieved by simply putting the files in the Magic Briefcase. Data in the Magic Briefcase can be shared and synced with as many computers as you desire. Another unique feature SugarSync offers is the ability to perform simple edits of files remotely; most services require that you perform you edits using the local computer only.
SugarSync really does just about everything; the only thing we could ask for is more scheduling tools and more preference options.
SugarSync can share in every way and in more ways than any other online backup service reviewed. It can do all of the expected things like share folders and assign permissions to files and folders. You can also send files of any size using SugarSync and you can share photo albums. Unlike most services, SugarSync will let you view, share and sync between multiple devices and computers. The easiest way to share between computers is using the Magic Briefcase, any files you put in the Magic Briefcase can be synced with your other computers automatically and instantly, nice.
In addition to the usual sharing tools, SugarSync also has iPhone, Blackberry and Android specific applications and a website version that is optimized for mobile devices. You can view and share your files from your mobile phone and photos taken with your mobile phone can be automatically synced to your SugarSync account. With the iPhone app available through iTunes you can view Word, Excel, PowerPoint & PDF files and photos. With SugarSync on your iPhone you do not have to physically load files onto your phone for portability, you can access all of your files and folders in the Magic Briefcase through the iPhone. You can also send large files through the app using the iPhone.
