To protect your computer from data corrupting, CLab Co., Ltd. has designed a very practical backup and recovery program, called ‘Backup dD’ that provides you with many useful features and the explicit instructions. This –simple-but-highly-effective program helps you backup and restore the critical data by minimizing the hard disk space with the standard compression and 128 bit encryption algorithm. The scheduler will automatically backup your file system . Apart from those features, Backup dD also gives you the capability of retrieving data in a similar way to the source control software: instead of restoring the data in entirely, the versions and baseline control features are able to restore a single file from each different versions.
