Backup & DR
Backup and disaster recovery in the age of virtualisation. The increasing use of virtualisation has changed the way disaster recovery is carried out because Virtualisation changes everything and increases the number of options. Data can be easily backed-up as part of an image of a given virtual machine (VM), including application software, local data, settings and memory. Disaster recovery is cheaper, quicker, easier and more complete in a virtual world. In the idiom of backup, faster recovery time objectives (RTOs) are easier to achieve. There are a number of different approaches, from tightly integrated hypervisor-level VM replication through to disaster recovery as a service (DRaaS).
