CommVault SQLiDA: Unable to get SQL version

Recently¬†one of our development servers crashed. Upon recovery we started to receive the following error messages when backing up the Microsoft SQL databases: “Unable to get the SQL Version for the server [DEVSERVER]. Please check if the SQL Services are running.

It’s important to note:

  • Before the crash the backups ran fine;
  • the file “SQLServerInstanceList.txt” listed the following information: “(local);Clustered:No;Version:11.0.5058.0“;
