Simple Data Backup allows you to create on-demand non-proprietary backups efficiently.
Since Simple Data Backup, as stated above, is non-proprietary, the default backup format is just a filesystem duplication (a straight file/folder copy) which translates to; never having to worry about not being able to access the data or restore from it. The UI is pleasing to the eye and very uncomplicated. A comprehensive help file is also included if you get stuck at any stage.
You will be able to perform on-demand backups of all your folders/files drive to drive, on a custom schedule or whenever you log on to your machine. Simple Data Backup can also be utilized to back up to a network drive, flash drive, or another hard drive to the Cloud using FTP, SSH, WebDAV, etc. If you need to create an identical folder/file structure on a backup drive, it allows you to compress the data as .ZIP or LZMA-compressed .7z files.
Simple Data Backup will also backup files that are in use, and monitor for any errors alerting you via email or SMS, making it an extremely well-rounded free backup tool.
Limitations:
The Free edition is perfectly functional, however, some advanced functionality is disabled. The Pro edition enables advanced functionality such as backing up to the 'Cloud'/remote servers via FTP/SSH/WebDav, email alerts, web reporting (backups can report status to the web so you can view status anywhere), and the ability to create multiple backups.
