Dear Commvault Team,

We are planning to implement a replication solution that utilizes the VSS service on a Windows machine. At the same time, we would like to perform backups of SQL Server (MSSQL) and files using Commvault on the same machine.

Could you please advise on how to achieve this setup without any issues or conflicts between Commvault and the replication solution?

Thank you in advance for your assistance.

Best regards,!-->

By default Commvault does not use VSS for SQL backups. I am told that there are a few drawbacks to using VSS for SQL, and you must opt in using a checkbox for VSS on the SQL backup config - so keep the default and there should be no conflicts at all.

Thank You Damian Andre for your answer

What about File backups ? I see VSS option and using uncheck for File Backups. 

 

But when I test it; The windows OS system always opening VSS Service  (started status. espacially for in use files in file backups) I want to take file backup without using VSS service. (Prevent VSS backup conflicts with other backup Software)

Thank You for your valuable answer again
