I was given a linux server to repurpose, but first of all, I want to back it up but I don't know username and password, and it may be encrypted. Now I am running this noisy server, there are only 4 items I can choose: Language, Session, Restart or Shut Down. Also, a field to enter user's info. Could you please tell me if this is possible, and if so then how?

If it's not encrypted, you can attach the drive as a secondary drive to another linux machine and try running
If it is encrypted, then you're likely out of luck. You can try some basic default passwords for the root account which are googlable, but if this is truly just to learn linux then I suggest you blow it away and install linux from scratch, and use a book such as this one or it's sequel for a good primer. The former does give a brief intro to *nix commands on the bash shell, which probably doesn't mean much to you know but if you progress then it will.
