For businesses, #cloud based #backup and #recovery has become common these days. If backup is fast enough to fit within a backup window, and if recovery times hit recovery time objective ( #RTO ) and recovery point objective ( #RPO ) service levels, you’re golden. After that, it gets complicated. Backup and recovery are critical components of disaster recovery (DR), but alone they can’t assure that application processing continues uninterrupted. Many enterprises have built their DR plans around remote sites because they already own multiple data centers, or they have the budget for secondary hot sites. However, unless they have an extra data center hanging around — or can afford to lease a secondary hot site — midsized and small businesses were out of luck for remote DR. In response, many cloud service providers and disaster recovery vendors took the cloud-based backup and recovery model to its logical next step: failing-over applications to the cloud.
