From the developer: "Backup utility for automatic and real-time mirroring of local folders/drives to another local/network/removable drive/disk. In real-time mode, it performs RAID-1 type of mirroring on local/network drives in software on per file basis and is capable of mirroring open files. In auto-sync mode, synchronization is done at the specified time interval in the background. You can exclude/include subfolder/file types from mirroring. It can also archive history of files under mirror folder in a series of zip files periodically. It is fully integrated with Explorer and has simple, intuitive and flexible user interface through property page of the folder/drive in Explorer. Once a mirror folder/drive is set up, mirroring will be done in the background without requiring any further effort from the user saving his/her valuable time."
