We are a financial company and we have redundant data centers, with a VMware Metro Cluster staged between the two locations. We have Rubrik running in our data center and it is used for backing up our on-premises infrastructure.
We keep the backup of the environment on-premises for two weeks, just to be able to restore in case we lose or corrupt part of the virtual infrastructure. We also send copies of some of the data into the cloud for long-term archiving because we're under a regulatory requirement to store certain parts of the business data for up to seven years.
At this point, our environment is probably close to 90% virtual. We use physical servers for market data and essentially, there is nothing to back up on those systems because there's no data that's worth saving there. Should one of these servers fail, we just put a new one in place. It would be deployed, including the operating system, and it would start processing market data for us. We consider these as compute nodes and there is no persistent data on them.
We are highly virtualized, so Rubrik is used to back most of the VMs up. We are running VMware ESXi for our VMs, and application-wise, we are a Microsoft shop so we backup SQL Server, Exchange Server, and Microsoft file shares. We also back up a lot of business data, which is contained outside of that server.
