Question

Dear Team,

I am looking for any information of RTO (Recovery Time Objective) and RPO (Recovery Point Objective) of AWS EC2, can someone have this kind of information?

Thanks,

Hi,

In addition to Oleksii's answer, I suggest to read https://aws.amazon.com/blogs/mt/establishing-rpo-and-rto-targets-for-cloud-applications/

This blog post details the various aspects of RTO and RPO for cloud applications and the standard AWS recovery models: 
1. Backup & Resrore
2. Pilot Light
3. Warm Standby

if you store data in EC2, you can regularly create snapshots. RPO would be the time between two snapshots

For example you can use AWS Backup for it

https://aws.amazon.com/getting-started/hands-on/amazon-ec2-backup-and-restore-using-aws-backup/

But actually it's not the best practice to rely on EC2 as data storage. The better way is to keep EC2 as an immutable and easily changeable compute (add and remove EC2 instances as you need during scaling)

RTO would be the time when a particular EC2 instance recovers after the failure, but again, it's better to remove the failed instance and create a new one instead. At least start designing such an approach
