Joe used to take his hard drive backups to work with him. When he was laid off, however, they wouldn't let him bring home anything, so he lost his backups. So he advises keeping them somewhere else. Unless you own the company. Leo says that's a very good point since they usually escort you out of the building to make sure you don't take anything company owned. This is also a reason to encrypt backups, just in case. It's also a good idea to send backups to someone else so they are off-site as well.
