For one if your clients sites run on databases, take orders, support requests, etc... The databases might not be in sync from a once nightly backup, and operating out of sync on another server could potentially put them further out of sync.
And of course, you realize this won't give you 100% uptime.
Other than that, I'd say its a good effort at having a redundant solution.
