Disaster Recovery as a Service (DRaaS): DRaaS is a third-party service that provides organizations with a secondary site infrastructure, which employs cloud computing for application and data recovery from synchronous or asynchronous replication1.

Fault Tolerance and Redundancy: A fault-tolerant disaster recovery site with fully redundant equipment ensures that all critical systems and components have backups ready to take over in case of failure1.

Real-Time Data Synchronization: This feature ensures that data is continuously mirrored to the disaster recovery site, allowing for real-time recovery and zero data loss during failover1.

Hot Site: A hot site is a fully operational offsite data center equipped with hardware and software, network connectivity, and real-time data synchronization. It is ready to assume operation at a moment’s notice, which aligns with the description provided1.

Minimal Downtime: The use of a hot site allows for minimal downtime during a disaster, as the site is already running and can take over immediately without the need to set up or configure equipment1.

AWS IAM Roles: AWS Identity and Access Management (IAM) roles allow for permissions to be assigned to AWS resources without the use of static credentials. Roles provide temporary credentials that are automatically rotated.

Service Role: The ‘get-pics’ service role created by Rebecca includes a permission policy for read-only access to the S3 bucket and a trust policy that allows the EC2 instance to assume the role.

Temporary Credentials: When the application runs on the EC2 instance, it uses the temporary credentials provided by the role to access the S3 bucket. These credentials are dynamically provided and do not require developer management.

Developer and Admin Roles: Since the EC2 instance has the necessary permissions through the service role, the developer does not need to manage credentials. Similarly, the admin does not need to grant explicit permission to the developer because the permissions are already encapsulated within the role.

Security Best Practices: This approach adheres to AWS security best practices by avoiding the sharing of static credentials and minimizing the need for manual credential management.

An incremental backup involves backing up only those files that have changed since the last backup of any type (full or incremental). This approach saves time and storage space compared to full backups by only copying data that has changed.

Incremental Backup Process: After a full backup is taken, subsequent incremental backups only include changes made since the last backup.

Efficiency: This method is efficient in terms of both time and storage, as it avoids duplicating unchanged data.

Comparison with Other Backups: Unlike differential backups, which copy all changes since the last full backup, incremental backups only include the changes since the last backup of any kind.
