Protecting a virtual workload is much easier compared to protecting a physical data center, in a legacy way, for several reasons:
- Virtualization provides encapsulation, so a VM is usually a set of files that can be easily managed.
- Virtualization provides hardware independence, where a VM can run as it is (without any changes) on different hardware, maybe also with different sizing, but using the same hypervisor (or a compatible one).
- Different types of data replication can be used, from traditional storage array replication to VM replication.
- On the DR site, you can, potentially, and for a limited number of workloads, use a single server that has enough computing and storage capacity.
- Cloud DR as a Service (
