4Sync and Dropbox are best known as online collaboration tools and for file storage on the Web. They differ from true backup sites like Carbonite, which actually backs up your entire computer when you install it.
What 4Sync and Dropbox do is provide folders in which you can store files securely online and share folders with team members. Dropbox in particular is so effective as a collabortion tool that it is one of the most highly used tools on the Web. But adding files to a Dropbox or 4Sync folder is a manual process, which is very easy, but it in no way ensures that your entire computer is backedup.
The feature sets of 4Sync and Dropbox are very similar. Both products provide the ability to share files and folders and allow users to backup servers in addition to desktop computers. 4Sync is currently only available in English, however, while Dropbox has versions in English, French, German, Japanese and Spanish.
Free Dropbox accounts are given 2 GB of storage space, along with an extra 500 MB for each referral made (up to 18 GB). Paid Dropbox accounts get either 50 or 100 GB of space, depending on the plan, and an extra 1 GB per referral. Companies can also obtain 1 TB or more of storage space through a team account.
In contrast, 4Sync provides 15 GB of storage space to its users for free. You cannot increase this capacity by referring other users to the service, however. Paid users are then given 100 GB of space. Greater storage capacity is not available at this time.
Unfortunately, technical support is neither product's strong point. Dropbox and 4Sync do not offer phone support or live chat to answer questions. If your software stops working, you can only contact Dropbox or 4Sync over email. Both products do have an online help center that you can check for answers, however.
Dropbox offers a mobile app for the iPhone, Android, Blackberry. 4Sync also provides a app for the same mobile devices. All of the apps allow users to quickly manage folders, browse documents, and download files onto their mobile device.
The pricing options of the two products are somewhat different. They both have a free version, as mentioned above. Dropbox also has the Pro 50 plan for $9.99/month or $99/year, and the Pro 100 plan for $19.99/month or $199/year. Team accounts with customized price quotes are also available.
4Sync just offers the Premium Plan, but its price varies depending on the length of the plan. It costs $9.95 for one month, $7.98/month for three months, $7.16/month for six months, and $6.50/month for a year. This means that 4Sync is slightly cheaper (provided you pay in advance) for the same amount of space.
There's a reason 4Sync and Dropbox are top ranked - they're both great applications. That said, if your company is going to need a fairly high level of capacity, you may want to choose Dropbox. If you don't need as much space and would prefer a free or slightly more affordable service, 4Sync is a solid alternative.
