During AWS Disaster recovery you need a solid disaster recovery plan that helps organizations stay up in the event of failure or attack. when it comes to disaster recovery, this versatile, decentralized system is an ideal solution for your business.

Determine your RTO
Recovery Time Objective (RTO) represents the allowed time it would take to restore a process back to service after a disaster event occurs. Before you can weigh downtime costs against the cost of data backup and recovery, you have to determine your company’s recovery time objective (RTO). Calculate your Recovery Time Objective (RTO) is more important for a successful recovery plan. This is the maximum length of time your recovery process can take to get everything back online without inflicting unacceptable losses for your business.

Determine Your RPO
Recovery Point Objective (RPO) defines the acceptable amount of data loss measured in time, prior to a disaster event happening. The selection of RPO and RTO should reflect the needs of your enterprise. your RPO must ...
... be narrowed by scheduling more frequent backups. Recovery Point Objective is the maximum amount of data loss we assigned to recover as measured in time.

Test your disaster recovery plan

AWS disaster recovery planning method
With disaster recovery planning having different methods based on your requirements you should choose your planning method.

Backup and restore
Backup and Restore is the first and least expensive disaster recovery method on the list. In this method, you have a backup of your data and then when you need to restore the data you should restore it from your backup. Restoring data should take more time lots of time and resources.

Pilot light
In pilot light, the core function is always running on the cloud. During Disaster the data is synced, and the database is always on and ready to go.

Warm standby
In this method it could make the duplication of systems core elements and keeping them running all the time, it results in very less downtime. At the time of the disaster, the duplicate comes to action and maintains the operation.

Hot standby
It is a full replica of data and the applications running in a different location. So, at the time of the disaster, the system simply redirects everything to the other location.
