Exchange 2010 Backup Terminated with catalogue pruning capability alert

Hello Guys .

I'm running on Networker 8.0.1.1.Build 163 and running Schedule backups Daily basis. My client is Exchange 2010 and  Running schedule backups daily basis.

Yesterday I found that the backup job has failed with below Generated messages on NSR. I'm bit struggling with the Issue and can anybody help me with the experience you have? May be some basics I might have missed as I just got into backup with networker..
