Back4Sure Portable (64-Bit) is a program for making backup copies of your documents, pictures, music, videos and anything you find valuable. The files to copy may be distributed all over your computer, even on different drives. Back4Sure Portable (64-Bit) will gather all the files you've selected for backup and make a copy of them into a specified target directory. The folder with the drive letter of the source drive and the directory structure will be automatically created in the target directory, so all your files will be stored correctly and easy to find. In this process, Back4Sure Portable (64-Bit) will only copy files that have changed since the last backup, so even a large number of files are backed up as fast as possible.
