Enabling S3 Object Versioning and Using It

Enabling Versioning:

1. Log in to the AWS Management Console and navigate to the S3 service.
2. Click on “Create Bucket” to create a new S3 bucket.
3. Enter a globally unique name for the bucket and select a region for it.
4. Leave the default settings for the remaining options and click on “Create Bucket”.
5. Once the bucket is created, click on its name to open its details page.
6. Click on the “Properties” tab and then click on “Versioning”.
7. Click on “Enable Versioning” to enable versioning for the bucket.
8. Now, if you upload a file with same name multiple times then multiple versions of that file would be maintained

Preventing Accidental Delete

1. Click on the “Properties” tab and then click on “Versioning”.
2. Scroll down to the “MFA Delete” section and select “Require MFA Delete” to enable MFA (multi-factor authentication) for object deletions.
3. Save the changes and close the “Properties” tab.
4. Delete the object using the AWS CLI:

   aws s3 rm s3://your-bucket-name/file.txt

5. You should receive an error message saying that the object cannot be deleted without MFA.
