Can I set up S3 to automatically delete files after a certain period of time?

Question

Accepted Answer

S3 Lifecycle Policies are a set of rules you define for your bucket to automatically manage your objects . The specific rule for deleting files is called an **Expiration action**, which tells Amazon S3 to permanently remove objects that meet the rule's criteria . These rules can be applied to all objects in a bucket or filtered by prefix (e.g., a folder path), object tags, or object size . There are two main ways to set up a lifecycle policy: using the AWS Management Console or the AWS Command Line Interface (AWS CLI). Open the Amazon S3 console and navigate to your bucket. Click on the **Management** tab, then select **Create lifecycle rule** . Give your rule a name. Then, choose the scope: apply it to the entire bucket or limit it to objects with a specific prefix (like 'logs/') or tags . Under **Lifecycle rule actions**, select **Expire current versions of objects** (or a similar expiration option). Specify the number of **days after object creation** when the objects should expire and be deleted . Review your settings and click **Create rule**. // 1. Create a JSON file (e.g., lifecycle.json) defining the rule.
// This example deletes objects with the prefix "logs/" after 365 days.
{
  "Rules": [
    {
      "ID": "DeleteLogsAfterOneYear",
      "Status": "Enabled",
      "Filter": {
        "Prefix": "logs/"
      },
      "Expiration": {
        "Days": 365
      }
    }
  ]
}

// 2. Apply the lifecycle policy to your bucket using the AWS CLI.
aws s3api put-bucket-lifecycle-configuration \
    --bucket YOUR_BUCKET_NAME \
    --lifecycle-configuration file://lifecycle.json **Delayed Execution:** After a rule is met, there can be a delay (sometimes several days) before Amazon S3 actually deletes the objects. The system queues the work asynchronously . Billing for the storage stops when the rule is met, even if the deletion hasn't occurred yet . **Versioned Buckets:** If your bucket has versioning enabled, you can set up separate rules to delete **noncurrent versions** of objects. You must specify the number of days after they become noncurrent . **Test Thoroughly:** To prevent accidental data loss, always test your lifecycle rules on non-critical data first . **Multiple Rules:** If you have multiple rules that could apply, Amazon S3 follows a general rule where permanent deletion takes priority over other actions .
