Backups failed on cluster - Cannot load the DLL xp_sqlbackup
Error reads: Cannot load the DLL xp_sqlbackup.dll, or one of the DLLs it references. Reason: 126(The specified module could not be found.). [SQLSTATE 42000] (Error 0). The step failed.
SQL Backup is installed and is used on both sides of the cluster. 1 named instance runs on Node-A and 3 different named instances run on Node-B. The named instance on Node-A failed over to Node-B. That is the instance that failed to backup.
What do I need to do to prevent this error? I want the backups to still run if a fail-over occurs.
