In order to configure lifecycle rules for Amazon S3 versioning, go to the Management tab on the page of the selected bucket. The message is displayed at the top of the page if configuration changes have been applied: Successfully edited bucket versioning.
In the Bucket Versioning section, click Edit.īucket versioning is disabled by default.Ĭlick Enable to turn on bucket versioning.Ī tip is displayed that you might need to update your lifecycle rules. Open the Properties tab for the selected bucket. Click the bucket name to open bucket details. In this example, I select the bucket with the name blog-bucket01. In the navigation pane, click Buckets and select the needed S3 bucket you want to enable versioning for. Click Services and then select S3 in the Storage category. Sign in to AWS Management Console by using the account with enough permissions. What is an S3 bucket? Read the blog post to learn more about Amazon S3. The old versions can be deleted or moved to more cost-effective storage (for example, cold storage) to optimize costs. Extra costs for storing additional versions should not be high if you configure the lifecycle policy properly, and new versions replace the oldest ones. You can use the lifecycle policy to define how long versions should be stored in an S3 bucket to have a form of Amazon S3 backup. Amazon S3 versioning can be used without additional S3 backup software. If the object is deleted, the “deletion marker” is applied to the object, but you can reverse this action and open a previous version of the object before deletion. You can access and restore previous versions of the object. Multiple versions of the same object are stored in a bucket. When changes are made to a file (that is stored as an object in S3), then a new version of the object is created. Object versioning is an effective feature in Amazon S3 that protects your data in a bucket against corruption, writing unwanted changes, and deletion.
This blog post explains how you can back up S3 buckets to have a backup copy of data stored in Amazon S3 by using Amazon S3 versioning and AWS CLI. Use s3cmd or s4cmd to download files from a bucket to a local file system on a Linux machine.Use the sync tool in AWS command-line interface (CLI) to copy files from AWS S3 to an EC2 instance.Configure AWS S3 replication from one S3 bucket to another.
Software failure can cause similar results. Data can be deleted or corrupted if a user who has access to an S3 bucket deletes data or corrupts data by writing unwanted changes. In some cases, you may need to back up data stored in Amazon S3 buckets to avoid data loss caused by human error or software failure. If a data center in one zone becomes unavailable, you can access data in another zone. Unlike Amazon Elastic Block Storage (EBS), where redundant data is stored in one availability zone, in Amazon S3, redundant data is distributed across multiple availability zones. This storage is widely used to store data backups due to the high reliability of Amazon S3. Files are stored as objects in Amazon S3 buckets.
