Glacier S3 oversize

Hello,

The discrepancy in storage size is likely due to:

• Glacier's Storage Calculation: Glacier calculates storage size based on the total amount of data uploaded, including metadata and chunked uploads. This can lead to a larger reported size.

• Multipart Uploads: The 512 MB multipart upload size setting can cause additional overhead, increasing the stored size.

• Versioning and Retention: If versioning is enabled, multiple versions of files are stored, contributing to the larger size.

To reduce the storage size:

• Verify Versioning Settings: Ensure you're not storing unnecessary file versions. Check your Glacier vault for multiple versions and clean up if needed.

• Optimize Multipart Upload Size: Consider increasing the multipart upload size to reduce overhead. This can minimize the space used by chunks and metadata.

• Run a Glacier Inventory Report: Generate an inventory report to identify the actual data stored and any potential issues.

• Consider Using S3 Lifecycle Policies: Automate the deletion of unnecessary data or transition to more cost-effective storage classes with lifecycle policies.

• Check for Duplicate or Unnecessary Files: Review and remove any duplicate or unnecessary files to reduce storage size.
