In today's cloud computing environment, protecting an organization's data and IT infrastructure is critical to ensure business continuity. Moreover, in situations of hardware failures in the cloud environment,  it is essential to be able to recover from failure and restore the data by meeting the expected recovery time objectives (RTOs). It is therefore necessary to keep a backup of the critical data so that there is no data loss in case of such events.

Although cloud providers ensure the reliability of their storage resources, in the event of catastrophic disasters, it's possible that the entire IT infrastructure goes down or is destroyed. In such cases, blaming the cloud provider for the outage may not help in bringing back the business online quickly. When organizations manage their own data center, they have more control over it and can mitigate risks. However, when data is moved to the public cloud platform, very little can be done to recover data in the event of failures.  

It is therefore necessary to ensure that a copy of the data is maintained at other locations from where it can be easily recovered or restored. Lack of data backups may put the hybrid cloud of your organization at risk.  

Redundant copies of the data should be distributed across geographical locations. With the AWS Cloud, duplicate copies of the data should be kept in different availability zones or regions. Distributing the redundant copies in this way minimizes the damage that can occur in the event of outages in a particular data center: 

Replication techniques can be leveraged to ensure that a mirrored copy of the data is maintained and updated frequently, so that the latest copy exists on the mirror site.
