I think the first will be check the server’s configuration (it is an AD, a TERMINAL SERVER, it is a DATABASE SERVER.,What applications are running in VMWARE, what type of RAID,etc)
it may be necessary to install the operating system again and reconfigurations the raid system, then a backup system will be established depending on the type of application, this may have extra costs for example if it is necessary to buy a backup hardware or pay a space in the cloud but obviously it will be informed in the initial diagnosis
