Comodo Backup Format

In the Backup format: window, what is the difference between CBU File and Simple Copy? Why would I choose one over the other?

Hi etopro

A CBU file will backup your file/files with a .cbu extension. You will need CBU 2 backup to restore this file. A “simple copy” will copy the file from one location to another keeping the original extension. You can restore this file by simply drag and drop or copy and paste.
