Cloud File Synchronization

You place a file on your computer.  It is immediately copied to the cloud, using an encrypted transmission application and is then stored in an encrypted form.  That is how cloud file sync works.  Changes made to the file on your computer or to the file in the cloud are immediately synchronized to other copies of the file.  If the file exists on multiple computers in addition to the cloud – say your laptop and your assistant’s desktop – the file is updated in all locations.  In many cases, the file storage site has version control and the ability to undelete a file.

Cloud file synchronization can provide some business continuity but is not a traditional backup.  Since it assumes a file exists in more than one place, it has a built-in “offline” benefit that means you do not need the Internet to have access to your files.  Most have apps so that you can access your files from a phone or tablet even if you aren’t synchronizing all of your files to that device.

There are two types of products to consider.  One is the primary file storage service.  You can also supplement that with a pre-encryption tool.

Microsoft Skydrive
