In this model, company data is stored as a backup in the cloud . In the event of failures in the production environment, this data is used to create new servers – usually through server images.
This model has the best cost , referring only to backup, but belarus mobile database the longest time for recovery.
Disaster Recovery Pilot Light
In this strategy, one server is kept active as a replica of the database and the other servers are turned off.
In case of failures in the main datacenter, the servers are powered on and the database server is scaled up to support the application traffic.

Multi-site Disaster Recovery
In this strategy, the conventional data center is fully replicated to the cloud , with all servers connected and receiving application traffic. Thus, both environments operate in production and, in the event of a failure in one of them, the other takes over the traffic and is able to support the entire application load.
This is the most expensive model , but it has the best recovery time , tending towards zero.
Agent Replication
Block-level data replication tools are used that, installed on local servers, replicate data to the cloud in virtually real time . The tool also orchestrates the disaster recovery environment testing process, facilitating the procedure.
This strategy is recommended for transparent replication of the environment, as it provides convenience in the DR process, without having to have servers running in the cloud unnecessarily.
