Ensure that your AWS S3 buckets utilize lifecycle configurations to manage S3 objects during their lifetime. An S3 lifecycle configuration is a set of one or more rules, where each rule defines an action transition or expiration action for Amazon S3 to apply to a group of objects.
Using AWS S3 lifecycle configuration, you can enable Amazon S3 to downgrade the storage class for your objects, archive or delete S3 objects during their lifecycle. You can also implement lifecycle configuration rules to expire delete objects based on your retention requirements or clean up incomplete multipart uploads in order to optimize your AWS S3 costs.
To determine if your Amazon S3 buckets use lifecycle configuration rules, perform the following:. If there are no rules defined on the Lifecycle page, instead a Get started panel is displayed:the lifecycle configuration for the selected Amazon S3 bucket is not enabled.
If the get-bucket-lifecycle-configuration command output returns the ServerSideEncryptionConfigurationNotFoundError error message, as shown in the output example above, there are no lifecycle rules currently defined, therefore the lifecycle configuration for the selected Amazon S3 bucket is not enabled.
To enable lifecycle configuration for your existing AWS S3 buckets by creating lifecycle rules, perform the following actions: As example, this conformity rule describes how to utilize Amazon S3 lifecycle configuration to tier down the storage class of S3 objects in this case log files over their lifetime in order to help reduce storage costs and retain data for compliance purposes. The transition actions for the lifecycle configuration rule defined as example are: 1.
One expiration action that enables Amazon S3 service to delete the objects a year after creation. Click Next to continue the setup process. For Transitions section, select Current version checkbox to add transitions for current version of S3 objects.
Once the necessary transitions are set, click Next to continue. For Expiration section, select Current version checkbox to add expiration actions for current version of S3 objects.

The Amazon S3 notification feature enables you to receive notifications when certain events happen in your bucket. To enable notifications, you must first add a notification configuration that identifies the events you want Amazon S3 to publish and the destinations where you want Amazon S3 to send the notifications.
You store this configuration in the notification subresource that is associated with a bucket. For more information, see Bucket Configuration Options. Amazon S3 provides an API for you to manage this subresource.
Amazon S3 event notifications typically deliver events in seconds but can sometimes take a minute or longer. If two writes are made to a single non-versioned object at the same time, it is possible that only a single event notification will be sent. If you want to ensure that an event notification is sent for every successful write, you can enable versioning on your bucket. With versioning, every successful write will create a new version of your object and will also send an event notification.
Object removal events — Amazon S3 supports deletes of versioned and unversioned objects. For information about object versioning, see Object Versioning and Using Versioning.
You can request notification when an object is deleted or a versioned object is permanently deleted by using the s3:ObjectRemoved:Delete event type.
Or you can request notification when a delete marker is created for a versioned object by using s3:ObjectRemoved:DeleteMarkerCreated. For information about deleting versioned objects, see Deleting Object Versions. Restore object events — Amazon S3 supports the restoration of objects archived to the S3 Glacier storage class. You request to be notified of object restoration completion by using s3:ObjectRestore:Completed. You use s3:ObjectRestore:Post to request notification of the initiation of a restore.
It sends these notifications when an object fails replication, when an object exceeds the minute threshold, when an object is replicated after the minute threshold, and when an object is no longer tracked by replication metrics.
It publishes a second event when that object replicates to the destination Region. For a list of supported event types, see Supported Event Types. Amazon SNS is a flexible, fully managed push messaging service. Using this service, you can push messages to mobile devices or distributed services. With SNS you can publish a message once, and deliver it one or more times.
Amazon SQS is a scalable and fully managed message queuing service. You can use SQS to transmit any volume of data without requiring other services to be always available. AWS Lambda is a compute service that makes it easy for you to build applications that respond quickly to new information.This service provides a durable, highly-available and inexpensive object storage for any kind of object — of any size.
Rather, we are going to discuss how objects are stored, and how life-cyles of objects are maintained. If a PUT request is successful, your data is safely stored.
However, information about the changes must replicate across Amazon S3. Also, S3 keeps multiple versions of the Object to achieve HA. Enabling or disabling versioning of one object within the bucket is optional. If you enable versioning, you can protect your objects from accidental deletion or being overwritten because you have the option of retrieving older versions of them. When you PUT an object in a versioning-enabled bucket, the noncurrent version is not overwritten.
Rather, when a new version of a file or an object is PUT into a bucket that already contains an object with the same name, the original object remains in the bucket, and Amazon S3 generates a new version ID.AWS S3 Lab Part 7 - How to manage lifecycle management of your data on s3 bucket
Amazon S3 then adds the newer version to the bucket. This service is automatically performed by S3 so that, as a user, your only concern is enabling and disabling the versioning in the bucket. Amazon S3 also provides resources for managing lifecycle by user need.
For example, if you want to move less frequently accessed data to Glacier, or set a rule to delete the file e. AWS allows the enabling of up-to lifecycle rules for achieving control of your objects in S3 buckets.
A typical configuration looks like this:. Here we have defined an S3 lifecycle configuration for objects in a bucket. Glacier i s another useful service from Amazon allowing inexpensive, highly durable storage services for archiving huge volumes of data.

This section provides examples of S3 Lifecycle configuration. Each example shows how you can specify the XML in each of the example scenarios.
Each S3 Lifecycle rule includes a filter that you can use to identify a subset of objects in your bucket to which the Lifecycle rule applies. The following S3 Lifecycle configurations show examples of how you can specify a filter.
The rule specifies two actions that direct Amazon S3 to do the following:. Transition objects to the S3 Glacier storage class days one year after creation. Delete objects the Expiration action 3, days 10 years after creation.
Instead of specifying object age in terms of days after creation, you can specify a date for each action. However, you can't use both Date and Days in the same rule.
If you want the Lifecycle rule to apply to all objects in the bucket, specify an empty prefix. In the following configuration, the rule specifies a Transition action directing Amazon S3 to transition objects to the S3 Glacier storage class 0 days after creation in which case objects are eligible for archival to Amazon S3 Glacier at midnight UTC following creation. You can specify zero or one key name prefix and zero or more object tags in a filter.
Note that when you specify more than one filter, you must include the AND as shown Amazon S3 applies a logical AND to combine the specified filter conditions. You can filter objects based only on tags. For example, the following Lifecycle rule applies to objects that have the two specified tags it does not specify any prefix.
When you have multiple rules in an S3 Lifecycle configuration, an object can become eligible for multiple Lifecycle actions. In such cases, Amazon S3 follows these general rules:. Transition takes precedence over creation of delete markers. You can temporarily disable a Lifecycle rule. The following Lifecycle configuration specifies two rules:.
In the policy, Rule 1 is enabled and Rule 2 is disabled. Amazon S3 does not take any action on disabled rules.AWSglacierS3.

Published February 02, by Subhash Vadadoriya. Using Lifecycle Policies. These policies are basically just rules that you can set up to move the data from S3 to Glacier at specific times. What Is Amazon S3 Glacier? Glacier is an extremely low-cost storage service that provides durable storage with security features for data archiving and backup. With Glacier, customers can store their data cost-effectively for months, years, or even decades. Glacier enables customers to offload the administrative burdens of operating and scaling storage to AWS, so they don't have to worry about capacity planning, hardware provisioning, data replication, hardware failure detection, and recovery, or time-consuming hardware migrations.
What is Amazon S3 Lifecycle Policies? AWS lifecycle rules are a set of options aimed to manage the data stored within the S3. It allows to move or to delete the objects after the certain number of days by configuring your own lifecycle rules. Here is a step-by-step guide:.
Select the bucket you want to set up lifecycle rule for and click on it. You will see the following menu on the right to it. Since the lifecycle is set up for the bucket in S3, you can just skip it and click Next. This step is setup to Permanently delete files from S3 after given days. Now you can see Lifecycle rule is applied on your selected bucket. You can also Edit Lifecycle rule if requirement changed:.
You can also disable Lifecycle rule if requirement changed:. Now try to download any files. The download button is disabled because files are stored in the Glacier, not in S3-standard. How to Retrieve files or Download Files from Glacier. Select a file and click on Restore from Glacier.
When you restore, you will have to choose how long you want the data to be accessible in S3 and also Retrieval types. After requested you need to wait for few hours and you can download files.

You can add rules in an S3 Lifecycle configuration to tell Amazon S3 to transition objects to another Amazon S3 storage class. For example:. When you know that objects are infrequently accessed, you might transition them to the S3 Standard-IA storage class.
You might want to archive objects that you don't need to access in real time to the S3 Glacier storage class. The following sections describe supported transitions, related constraints, and transitioning to the S3 Glacier storage class. In an S3 Lifecycle configuration, you can define rules to transition objects from one storage class to another to save on storage costs.
When you don't know the access patterns of your objects, or your access patterns are changing over time, you can transition the objects to the S3 Intelligent-Tiering storage class for automatic cost savings. For information about storage classes, see Amazon S3 Storage Classes. Amazon S3 supports a waterfall model for transitioning between storage classes, as shown in the following diagram.
Amazon S3 supports the following Lifecycle transitions between storage classes using an S3 Lifecycle configuration. For example, you cannot create a Lifecycle rule to transition objects to the S3 Standard-IA storage class one day after you create them. Amazon S3 doesn't transition objects within the first 30 days because newer objects are often accessed more frequently or deleted sooner than is suitable for S3 Standard-IA or S3 One Zone-IA storage.
Similarly, if you are transitioning noncurrent objects in versioned bucketsyou can transition only objects that are at least 30 days noncurrent to S3 Standard-IA or S3 One Zone-IA storage. You can specify two rules to accomplish this, but you pay minimum storage charges. For more information about cost considerations, see Amazon S3 pricing. You can combine these S3 Lifecycle actions to manage an object's complete lifecycle.
For example, suppose that the objects you create have a well-defined lifecycle. Initially, the objects are frequently accessed for a period of 30 days. Then, objects are infrequently accessed for up to 90 days. After that, the objects are no longer needed, so you might choose to archive or delete them.
As you move the objects from one storage class to another, you save on storage cost. You cannot access them directly through the separate Amazon S3 Glacier service.
Before you archive objects, review the following sections for relevant considerations.
