S3 Cross-location logging is not allowed for the bucket.
Understanding Amazon S3
Amazon Simple Storage Service (S3) is a scalable object storage service that allows developers to store and retrieve any amount of data at any time, from anywhere on the web. It is designed to deliver 99.999999999% durability and scales past trillions of objects worldwide. S3 is commonly used for backup and restore, disaster recovery, data archives, and big data analytics.
Identifying the Symptom
When configuring server access logging for an S3 bucket, you might encounter the error CrossLocationLoggingProhibited. This error indicates that cross-location logging is not permitted, meaning the target bucket for logging is in a different region than the source bucket.
What You Observe
While attempting to set up logging, you receive an error message stating that cross-location logging is prohibited. This prevents you from successfully enabling logging for your S3 bucket.
Exploring the Issue
The CrossLocationLoggingProhibited error occurs when the target bucket for storing logs is not in the same AWS region as the source bucket. AWS S3 requires that both the source and target buckets be in the same region to ensure data consistency and reduce latency.
Why This Happens
This restriction is in place to prevent potential data transfer costs and latency issues that can arise when data is logged across different regions. It ensures that log data is stored efficiently and securely.
Steps to Resolve the Issue
To resolve the CrossLocationLoggingProhibited error, follow these steps:
Step 1: Verify Bucket Regions
First, check the region of both your source and target buckets. You can do this via the AWS Management Console or by using the AWS CLI:
aws s3api get-bucket-location --bucket <your-source-bucket-name>
Repeat the command for the target bucket to ensure they are in the same region.
Step 2: Create a New Target Bucket
If the target bucket is in a different region, create a new bucket in the same region as the source bucket. Use the AWS Management Console or the following AWS CLI command:
aws s3api create-bucket --bucket <new-target-bucket-name> --region <source-bucket-region>
Step 3: Enable Logging
Once you have a target bucket in the same region, enable logging on the source bucket:
aws s3api put-bucket-logging --bucket <your-source-bucket-name> --bucket-logging-status '{"LoggingEnabled": {"TargetBucket": "<new-target-bucket-name>", "TargetPrefix": "logs/"}}'
