AWS Tutorial for Beginners:How to add Cross Region Replication CRR Rule to an S3 Buckets

How to add Cross-Region Replication (CRR) Rule to an S3 Bucket?
How To share files from one region to another region with CRR rule?

Lets see what are the CRR rule.

1.Login to the AWS Console and search for s3 and create a bucket.
2.your wish....if you want public access uncheck this.
3.Create another bucket(This is the destination for objects).
4.versioning must be checked for both source bucket and destination bucket
5.Now Upload files in source bucket.
6.Now check the destination bucket .
7.We have to give crr rule to the source bucket then only it will replicate in
Destination bucket.lets give those rules..
8.your wish....if you want entire bucket choose entire bucket...
otherwise mention particular tags(we will do this later)
now select entire bucket
9.choose destination bucket here...because we have already created the bucket now just select that bucket
10.here also you can create new bucket
11.successfully created the rule...now upload the new object to the source bucket
12.uploaded one more image name as image2.png
now go and check the destination bucket whether it is replicated or not
13.yes it is here...replicated from source bucket...
But we didnt get the image1 file because only feature objects after creating the CRR rule only
those objects will replicate...Already existing objects wont replicate...
14.Now lets check some deletions and versioning and delete markers here...
15.just now i deleted the image 2 now delete marker available...but it wont replicate in the destination bucket
lets check.
16.If we delete any original file in bucket ,delete marker will apply each bucket.
17.Only objects which are uploaded after creating the CRR rule will replicate
in detination bucket...No delete markers,versions replicated...
18.Now again add CRR rule to destination bucket and replicate the objects from
destination bucket to source bucket...
19.this is the destination bucket...click on it and goto management
and replication
20.if that error comes we need to check the rules....
That means we have already created the rule(While getting the error
the role already created) so we need to go back and add that rule...
21.Now lets add some objects to destination bucket and see what will happen in
source bucket...
22.yes...its replicated from source to destination.....
we can share objects mutually....
from source to destination
destination to source.....
23...
