When you initiate a disaster recovery service contract, use
backups to test for system compatibility problems and bugs in your
disaster recovery system. As time passes, perform periodic tests
(for example, every quarter) to ensure that your systems remain
compatible and your disaster recovery procedures work well. Also
test your disaster recovery system whenever you change it. You can
either notify the facility in advance, to minimize costs and interruption
of the recovery facility, or you can do a full-scale simulation.
Either way, prepare a test plan and have it approved by all parties.
