Spam?  Don't be so silly.  It is an answer to your question.  It's not my fault you don't understand it and/or don't like it.

There is nothing wrong with the archiving, it's working fine.  It's something you're doing to look at it.

Nic, do not spam, please, Its not solution and not answer on question.

At first screenshot archive opened in Total Commander and WinRAR archiver on windows OS.

Another example with empty folder name is under Midnight Commander on CentOS. Same situation. Its not problem with operating system, its problem with backup archiving mechanism.
