Hello @Selva.
There are a bunch of services provided by AWS.
- AWS Whitepaper
- Analyst Whitepaper
- Analyst Report
AWS Whitepaper uses the two common methods for DR:
- Recovery time objective- After the data loss it takes a specific amount of time to restore the business to service.
- Recovery point objective- Here the recovery happens in terms of time. Data here is measured in terms of time.
The traditional way of DR includes different methods such as site duplication, data duplication etc.
