How often are you backing up with Macrium? This is more of a preference thing, but you may want to implement a snapshot tool like Rollback Rx. Reason I say this is either you're running a backup every day (time consuming) or you're backing up once a week or more, at which point you could potentially miss days worth of data. Maybe not a big deal, but a snapshot tool will help fill in the gaps and the ones I mentioned have freeware versions so you don't have to pay a dime to use them.
