Cloud disaster recovery is a service that enables the backup and recovery of remote machines on a cloud-based platform.
Cloud disaster recovery is primarily an infrastructure as a service (IaaS) solution that backs up designated system data on a remote offsite cloud server. It provides updated recovery point objective (RPO) and recovery time objective (RTO) in case of a disaster or system restore.
Also known as cloud DR or cloud DRP.
Cloud disaster recovery typically provides similar services as an on-premises or company-maintained off-premises disaster recovery plan (DRP) facility, but in an economical, efficient and provider-managed platform. A cloud DRP vendor provisions users and storage space and continuously update designated systems with client software installed on each system. Users have the ability to add, edit and delete systems and storage capacity, without having to consider the back-end supported infrastructure.
A cloud-based disaster recovery solution enables the user to scale up the entire cloud DRP solution from some-to-many. The user is normally billed on a monthly basis only for the storage and client software licenses. Most Cloud DR also provisions backup and recovery for critical server machines that host enterprise-level applications like MS-SQL, Oracle, etc.
