Hi,
If you want to backup to a different region in AWS, you can use Cross Region Replication. This will be backup your content in one S3 bucket in X region to another S3 bucket in Y region.
You can go through links here for details and how-to:
Also if you don’t want backup but just want to safeguard against delete of any object in S3, you can use MFA delete. This will ask for your MFA token on delete of object.
Also you can use versioning so that even on delete, the previous version is available.
Also, keep in mind this all options will have some additional cost associated with it.
Let me know if you need more help.
Thanks
