Emacs itself probably isn't the right tool for this job: you could use
it to invoke other commands, but by itself it doesn't do this sort of
thing.

There are a million different solutions for backing things up, but I
think one of the simplest and most effective is rsync, which is likely
already on your machine (provided it's not windows). If you google
"rsync for backups" you'll get more information than you ever wanted.
