Intelligent Tiering Configuration

Intelligent Tiering Overview

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective access tier.

It monitors the usage patterns of objects and automatically moves them to the most cost-effective access tier.

By default, the Intelligent-Tiering storage class moves objects among three access tiers:

• Frequent Access - for files that are accessed frequently (the STANDARD storage class equivalent).
• Infrequent Access - a 45% lower-cost tier for files that have not been accessed for 30 consecutive days (the STANDARD_IA storage class equivalent).
• Archive Instant Access tier - an 82% lower-cost tier for files that have not been accessed for 90 consecutive days (the GLACIER_IR storage class equivalent).

You may also activate additional archive tiers to save even more on storage fees for files that are not accessed frequently.

• Archive Access - an 84% lower-cost tier for files that have not been accessed for at least 90 consecutive days (the GLACIER storage class equivalent).
• Deep Archive Access - a 95% lower-cost tier for files that have not been accessed for at least 90 consecutive days (the DEEP_ARCHIVE storage class equivalent).

Please note that files moved to the Archive and Deep Archive access tiers are not accessible immediately. You need to initiate a Restore first and wait from 1-2 minutes to 48 hours, depending on the access tier and retrieval method. Please check the AWS documentation for more details.

Additional archive tiers are configured by applying an Intelligent Tiering Configuration to the bucket. You may use CS Browser to perform this task with ease.

Please check the instructions below for more details.

To Apply Intelligent Tiering Configuration

1. Select the bucket you want to configure, then choose Buckets > Intelligent Tiering Configuration..

   

   The Intelligent Tiering Configurations dialog will open:

   

2. Click Add. The Add New Intelligent Tiering Configuration dialog will open.

   Configuration name - assign a name to your configuration. It may contain letters and numbers and is limited to 64 characters. The configuration name cannot be edited after the configuration is created.

   By default, CS Browser assigns a randomly generated ID as the name. You can edit it to reflect the configuration details.

   Below the Configuration name field are two tabs:

   • Filter - define the filter that identifies one or more files to which the configuration applies.
   • Actions - define the access tiers to apply to files covered by the filter.

Filter

You may define the filter based on the object's prefix, one or more object tags, or both.

Prefix - identifies one or more files to which the configuration applies (for example, 'logs/'). An empty prefix means all files.

Tags - define one or more tags to apply the configuration only to objects with the specified tags.

If multiple tags are defined, the configuration applies only to files that have all the specified tags. Amazon S3 performs a logical AND.

If you define both a prefix and one or more tags, the configuration applies to objects with the specified key prefix and tags. A filter can have only one prefix and zero or more tags.

Actions

Archive Access tier - when enabled, Intelligent-Tiering automatically moves objects that have not been accessed for a minimum of 90 days to the Archive Access tier.

Configure the number of days using Days until transition to the Archive Access tier.

Deep Archive Access tier - when enabled, Intelligent-Tiering automatically moves objects that have not been accessed for a minimum of 180 days to the Deep Archive Access tier.

Configure the number of days using Days until transition to the Deep Archive Access tier.
