I'm looking for ways to protect my critical EC2 instances from being terminated maliciously. Is there a way to set up a system where, for example, two or more accounts need to approve the termination of certain EC2 instances? Also, are there mechanisms available for automatic daily backups of specific EC2s? Thanks in advance for your help!

You can set up termination protection on your critical EC2 instances to prevent accidental deletions. AWS also allows you to implement IAM policies with strict permissions so only authorized users can perform terminations. For backups, using AWS Backup is a great option to automate daily snapshots of your EC2 instances.
If you're aiming for redundancy, you might want to look into Service Control Policies (SCP) if your account is part of an AWS organization. That way, you can deny termination permissions for certain accounts or users.
If your main goal is to just protect against deletion, regular backups are crucial. Using AWS Backup will allow you to specify instances for automatic daily backups, making it easy to restore them in case of accidental or malicious deletions.
You can enable termination protection directly from the EC2 attributes for those instances. Just run the command `aws ec2 modify-instance-attribute --instance-id --disable-api-termination`. This helps ensure no one can terminate them without an explicit action.
A solid method is to integrate CI/CD pipelines in your workflow. This way, only approved changes can lead to actions like instance deletions. When someone wants to delete an instance, they'd have to submit a merge request, which requires review before it can be executed, keeping your instances safer.
