We have a SQL Server which started to take backups by itself every now and then. It started for a few days ago.
When it fails an error is logged saying that source is "Microsoft SQL Server Native Client 10.0" It also says:
"SQLSTATE: 42000, Native Error: 3201 Error state: 7, Severity: 16 Error message: Cannot open backup device '{94C30FE5-1C62-45C7-8E28-4F67BCF89210}682'."
How can this happen? Can I find out what part of the code which does this?
It is not a part of any jobs or similar, the time for the backup is different from day to day, it does not try to take a backup every day but most of them. If it fails it retries a lot of times and after a veil its stops.
Edit: The first clue to find out why these backups were taken I found from Kevin3NF advise, were I could confirm that it was the SQL Server VSS Writer which were taken the backups. Then John Eisbrener commented that if it is VSS writer it is probably when one takes a backup of the entire OS. I then found that someone has had a similar problem: Why SQL Server Express 2012 take automatically backup in "Virtual Device" without virtual device configuration? We have now confirmed that it happens when our new 3rd party tool is taking a backup of the entire OS.
