Remove recursive scanning of backup file

[kwikadi]

set topdown=False inside os.walk., at least till you replace it with scandir (which looks pretty neat, might steal that idea)

I don't really get what you mean by "recursive scanning of backup file".

Also, If we set topdown=False we won't be able to ignore the directories (See this).

A very poor implementation would require you to scan the backup folder after backing up the entire drive, and removing offending folders.
Cant think of anything else right now. If I do, I'll let you know?

We're just trying to fix the bug that destination can't be a child of the source directory (while keeping the rest of the functionality of the script as is) right? because if that's the case I've thought of something. Too lazy to implement it though.

[kwikadi]

Huh. What is it?

[dufferzafar]

We just store all the directories in source and then walk over every one of them?

children = os.listdir(src_root)

for child in children:
    for cur_dir, dirs, files in os.walk(os.path.join(src_root, child)):
        ... rest of the code same ...

Now that I've written it, I can see that this is only a partial solution and won't work in all cases.
