Commvault – how to configure MSSQL failover cluster backup<\/h3>\n

In this article, we will focus on configuring backup for active-passive ms-sql cluster using commvault agent backup<\/p>\n

One of the my customer build the active-passive ms-sql cluster based on VMware vSphere 8 (with shared disks), but shared disk not support snapshots operation, so i need configure a agent backup.<\/p>\n

Of course you need to have a working firewall, because sql and commvault is in separate networks, don’t forget about DNS – it is usually the culprit of all problems.<\/p>\n

First of all i need install the ms-sql agent on both sql nodes in cluster. so i copied the .exe and install same version as my commserve – in my case 11.36.55. I using the authcodes for the registration, in my opinion is the simpliest way to register client.<\/p>\n

My collegue created a gMSA account<\/a> in AD only for our backup purposes (you can use classic domain user of course) So next step is add this account both nodes:\u00a0<\/p>\n
