+# Creating an automated RDS (Amazon Relational Database Service) instance and implementing a restore strategy using Terraform 
+
+A high-level overview of the steps involved, along with some guidance on troubleshooting the issues you're facing. 
+Please note that this overview assumes you have some familiarity with Terraform and AWS services.
+
+1. Set up the necessary AWS and Terraform configurations:
+
+- Ensure you have valid AWS credentials with appropriate permissions.
+- Install and configure Terraform on your local machine.
+- Create a new Terraform project directory and initialize it.
+
+2. Define your Terraform configuration files:
+
+- Create a .tf file (e.g., main.tf) for your RDS instance configuration.
+- Specify the required AWS provider and region.
+- Define the RDS instance resource, specifying details such as engine, instance type, storage, etc.
+- Define any necessary security groups, subnets, and parameter groups.
+
+3. Configure automatic backups and enable the backup retention period:
+
+- Specify the backup_retention_period for your RDS instance.
+- Enable automated backups by setting backup_window and maintenance_window parameters.
+
+4. Implement the restore strategy:
+
+- Create a new .tf file for the restore configuration (e.g., restore.tf).
+- Define a new RDS instance resource using the restored snapshot ID.
+- Configure necessary settings like DB instance identifier, engine, instance type, security groups, etc.
+
+5. Plan and apply your Terraform configuration:
+
+- Run terraform init to initialize your Terraform project.
+- Run terraform plan to verify the changes and ensure the configuration is correct.
+- Run terraform apply to create the RDS instance and implement the restore strategy.
