Hi Peter.
We have 2 different databases on the server(s) that had the problem,both getting transaction log backups every 10mins. Looking at the graph in sql backup they seem to occur at the same time.
I have grabbed the sql the sql backup tool generates for the job and added it to the end of this reply.
In answer to your last question:
'Is there a specific interval where the backups cause the CPU utilization to max out, or does it happen with every transaction log backup?'
No there is no specific interval where the backups cause a problem - its very random as to when the issue occurs on different servers. As I mentioned - all servers have 2 databases which have tranaction log backups every 10 mins.
