Opscentre report to report back arbirary timeframe for genuinely failed backups

Ops centre has a canned report for failed backups but thats not quite what I need: I need one that tells me a backup that ran and failed and didnt complete successfully at all over a period, ie the client wasnt backed up: thats primarily what we are interested in right?

In other words, lets take a typical weekends set of full backups: I need to be able to report policy/client combo failed all attempts at backup ie for that combo I have not achieved a successful backup. Lets say failed means any non-zero status.

I'm looking at the consecutive failures report....this may be what I'm after.

Thanks in advance for your input.Jim.
