You'll find that most web hosts do run offsite backups for business continuity (as Collabora alluded to). However, when businesses run their offsite backups, the backups are usually done as a part of a disaster recovery plan. They're also sometimes full images of a hard drive, so restoring a single cPanel account, home directory, mySQL database, or even a single email becomes a huge administrative pain for the web host. In this case, web hosts will charge for backups.
You'll also find, which is a bit less common, web hosts that run offsite backups as a courtesy to clients (also for disaster recovery). These are usually just cPanel archives that can be restored on servers as necessary, but sometimes they'll use software like Idera (R1Soft) that lets you do it yourself. Sometimes web hosts will still charge for backups when they're done on an account-per-account basis (both as a way to make money and due to the fact that it does take administrative time to find the backup and restore it).
I can think of several providers who use each method, so I wouldn't say that no web host runs offsite backups.
