Typically, a Service Level Agreement says what Service Level Objectives you
will provide to your customer if the use your system, nothing to do with
them justifying usage.

What you want is a document where your potential customer can do a self
business impact analysis of not having a backup and losing data and use the
lost potential business or legal impact as the justification that creates a
grade "pass" or "fail".

SAIC does a lot of contracts and service to customers.  So, maybe you really
did want an SLA sample, which unfortunately I cannot give you, considered
proprietary information at my company.
