As the name suggests, X-Backup is designed for if the worst happens and you lose all your data on your PC. It's a powerful, versatile and easy to use piece of software and has been periodically updated to improve both the security and speed of backups.
X-Backup will basically save any number of files and archive them in a Zip file or for really big backups, create a disk partition image. The interface has been based on Microsoft Office so if you think it looks familiar, you're right. This doesn't exactly make it look attractive but it's functional and clear. Most importantly, it clearly shows you an instant overview of your backup storage.
The most useful features are the scheduled and synchronized backups. You can use the X-Backup time line to schedule exactly when you want it to kick-in and start backing up your machine. However, make sure this is not when you are working as it's rather annoying whilst it takes over your entire system (with prompts first though). With synchronized backups, the program will detect any changes on your PC and backup new files automatically.
One concern with all that backed up data is security. X-Backup allows you to encrypt backed-up files with a 256 bit AES encryption key. If you do lose data from your hard drive, X-Backup also has a handy restore function which instantly re-transfers backed-up files to their original location.
