BChavetnoir, while it isn't SureBackup, I would offer a work-around that I presently use.
I wrote a rather interesting script, which iterates through protected virtual machines, always choosing the least-recently checked, mounts the backup to the B&R server, then scans it with our antivirus. Interesting results, solid peace of mind, knowing that I can do a truly offline file scan where an infected system cannot use a variety of avoidance techniques.
Such a methodology could certainly be adapted to run application-specific tests. For example in the case of an SQL server, the script could run a query on the master db of the production server for a list of active databases (and relevant file locations), then iteratively mount them to a test SQL server, run a simple DBCC query. If I remember correctly DNS is just a text file (don't quote me, I haven't looked myself) so similar tests could be accomplished.
Something like AD would be hard to test, so you'd need SB for that, but it's also very easy to isolate your AD backups into separate jobs with different schedules, giving you lots of time to test each.
