Who is the S3 bucket owner?
By default, an S3 object is owned by the AWS Account that uploaded the object. S3 Object Ownership gives you a simple bucket setting that changes this default behavior, so that new objects uploaded with the bucket – owner -full-control access control list (ACL) will instead be owned by you.
What happens to existing S3 objects when you enable versioning?
When you enable versioning in a bucket, all new objects are versioned and given a unique version ID. Objects that already existed in the bucket at the time versioning was enabled will thereafter always be versioned and given a unique version ID when they are modified by future requests.
What is the S3 feature that allows to you store and access older iterations of objects?
S3 versioning is a feature that keeps track of and stores all old /new versions of an object so that you can access and use an older version if you like. S3 Versioning is either ON or OFF.
Why can’t I access an object that was uploaded to my Amazon S3 bucket by another AWS account?
By default, an S3 object is owned by the AWS account that uploaded it. This is true even when the bucket is owned by another account. To get access to the object, the object owner must explicitly grant you ( the bucket owner) access.
How do I change ownership of a S3 object?
Every bucket and object in Amazon S3 has an owner, the user that created the bucket or object. The owner of a bucket or object cannot be changed. However, if the object is overwritten by another user (deleted and rewritten), the new object will have a new owner.
Is S3 versioning incremental?
Versioning in AWS S3 can be described simply as keeping incremental copies of the same file as you make modifications. In S3 versioning stores, all versions of an object and including all write even if you delete an object. S3 versioning is a great back up tool.
What is S3 lifecycle?
An S3 Lifecycle configuration is an XML file that consists of a set of rules with predefined actions that you want Amazon S3 to perform on objects during their lifetime. You can also configure the lifecycle by using the Amazon S3 console, REST API, AWS SDKs and AWS CLI.
What is delete marker in S3?
A delete marker in Amazon S3 is a placeholder (or marker ) for a versioned object that was named in a simple DELETE request. Because the object is in a versioning-enabled bucket, the object is not deleted. A delete marker has a key name (or key) and version ID like any other object.
Why S3 bucket is used?
Amazon S3 provides object (file) storage through a web interface. It’s built to store, protect and retrieve data from “ buckets ” at any time from anywhere on any device. Use cases include websites, mobile apps, archiving, data backups and restorations, IoT devices, and enterprise apps to name just a few.
How are objects stored in S3?
Data is stored as objects within resources called “buckets”, and a single object can be up to 5 terabytes in size. Objects can be accessed through S3 Access Points or directly through the bucket hostname.
Where is S3 data stored?
Objects stored in the S3 One Zone-IA storage class are stored redundantly within a single Availability Zone in the AWS Region you select. For S3 on Outposts, your data is stored in your Outpost on-premises environment, unless you manually choose to transfer it to an AWS Region.
How do I access my S3 bucket from another account?
To use bucket and object ACLs to manage S3 bucket access, follow these steps:
- Create an IAM role or user in Account B.
- Configure the bucket ACL to include at least WRITE permission for Account B.
- Configure object ACLs to include at least READ permission for Account B.
How do I transfer data from S3 to S3?
To copy objects from one S3 bucket to another, follow these steps:
- Create a new S3 bucket.
- Install and configure the AWS Command Line Interface (AWS CLI).
- Copy the objects between the S3 buckets.
- Verify that the objects are copied.
- Update existing API calls to the target bucket name.
How do I access S3 bucket from another region?
1. You need to specify the region your bucket is in, when you make the API/CLI call. You should do that even if the bucket is in the same region as your EC2 instance. You also need to launch your ec2 instance with appropriate roles to access the S3 buckets in your account.
