nobody has created any of the schedules coz its occuring a the time of running backup manually or by scheduled backup jobs
it is in cluster also and it is giving failure audit of another node AP server failure log in DB server event viewer
we tried to take backup in both node [DB and AP servers ] at both it is rebooting and givng blue dump in windows. there also unable to find the errors
my exp is very less and so iam unable to find the root cause but iam trying my level best this is the site which made me to know more when ever a issue comes
What commands are you using to run a manual backup?
The blue screen and windows dump is an issue. This would generate logs and dmp files. When a blue screen occurs, I'd be more focused on the hardware, drivers, or windows installation.
Post the actual backup command you are using. It is possible that due to a driver misconfiguration or failing hardware that the IO load from a backup will provoke a blue screen. But for that there would be some information in the windows logs, dump files or possibly in the SAN logs.
