Mystery Backup Database Job
The mystery backups just show a long alpha-numeric string in curly brackets. Anybody know what this is?


This might be a 3rd party software using Volume Shadow Service (VSS) backup .


  I would like to see if I can disable this job, but I have no idea where it is scheduled.


if you are using native TSQL backup, then disable the SQL Server writer service using services.msc

you can use sysinternal's process explorer to find out what the process or just ask your windows admin if they are doing snapshot of entire folders or machine.
