#8: Be Ready to Recover
Most companies have a solid backup strategy in place and do a great job backing up Exchange server data. However, many companies' backup plans are designed to meet business and recovery requirements that are several years old (and thus outdated). Business requirements change over time, so if you're working on a design that refreshes (rather than launches) an Exchange organization, be sure to review the existing backup policies to ensure that they meet current business needs. Be sure to include restore times as a part of the decision. In most circumstances, the time needed to restore Exchange is more important than the time needed to back up Exchange.
Specify that test restores are to be performed as part of a regularly scheduled, proactive process. Backing up an Exchange server involves both software and hardware technology, one or both of which can fail from time to time. Performing regular test restores will provide a greater chance of a successful real-life restore and will ensure that administrators know how to restore Exchange data after a disaster. . . .
