Once you've set your source and destination folders, right-clicking the profile and selecting Run will start the synchronization process. It's best to create a schedule so the program will back up your files automatically on a regular basis. Right-click on the profile's name and select Schedule. When prompted, click Yes to create a new schedule. You'll also be able to choose what time to sync your folders.
Here's where it gets a little tricky. If you really want a disaster-proof backup, you should create multiple SyncBackFree profiles and synchronize your source data to different folders, at different intervals, to maintain multiple copies of your data.
Why would you want to do that? Every time SyncBackFree syncs the two folders, it overwrites the previous version of the data in the destination folder. Maintaining multiple profiles that back up to multiple locations protects against losing your files to data corruption or, say, a particularly nasty bit of ransomware that encrypts your files and throws away the key.

You may also want to sync individual files for backup or sharing across several devices with SkyDrive (or Dropbox, or Google Drive, or...). That's simply a matter of copying the files you'd like to back up into your cloud-storage service of choice. Check out our comprehensive article explaining how to use SkyDrive, and remember, its name will be changing to OneDrive sometime soon.
