Verify that the contents of the file are the same on both EC2 instances.
Choose "Snapshots" on the left hand side and click on "Create snapshot"
Select the instance you want to create a snapshot of and click on Create snapshot
Use the newly created Snapshot to launch a new EC2 Instance: Click on "Actions" and select "Create image from snapshot". Follow the prompts to create an Amazon Machine Image (AMI) from your instance.
In the EC2 Dashboard, select "AMIs" from the left-hand side, Choose the AMI you created in the previous step.
Click "Launch Instance" and follow the instance creation instructions to launch a new instance.

aws s3 sync local-folder s3://bucket-name - This command syncs the contents of a local folder with an S3 bucket.
aws s3 ls s3://bucket-name - This command lists the objects in an S3 bucket.
aws s3 rm s3://bucket-name/file.txt - This command deletes an object from an S3 bucket.
aws s3 presign s3://bucket-name/file.txt - This command generates a pre-signed URL for an S3 object, which can be used to grant temporary access to the object.
