There is currently a total data volume of 25TB across the 36 servers. There are also 8 servers hosted in Azure which are currently protected via Azure Backup and Recovery, these have been named mission critical also. AHDB wish to protect all 36 VMWare and 8 Azure servers with local and offsite backups run multiple times during the day as opposed to the current single daily backup. There is also a requirement for local and remote offsite failover DR capability for the 25 servers marked as critical.
