||The program creates full and incremental backups that can be stored in a zip-file. Comparing folders and their contents (also by file content) is possible as well. With the a BackupFileSystem(BFS)-feature all files are zipped and the data is stored together with the filename in a zip file. This way problems with long file paths on CDs/DVDs can be avoided while the backup requires less size. The method is also less vulneralbe to file errors, becuase each file is stored in a separate zip file, so if one file breaks, only this file is broken and not the entire backup.
