![]() For a same key object, except for the only one latest modified object, all others are noncurrent versions. You can also check the actual noncurrent object versions by turning on Show versions in the Amazon S3 console. Find bytes of noncurrent versions that are taking storage costsĪmazon S3 Storage Lens helps you to identify bytes of noncurrent version per bucket that are taking storage costs. We walk through how you can protect your data by maintaining object versioning while lowering storage cost by retaining fewer noncurrent versions, giving you both cost-efficiency and data security. In this blog, we introduce how you can secure both data protection through object versioning and manageable data storage costs using S3 Lifecycle configuration. That is why customers are advised to enable versioning in the Amazon S3 security best practices. ![]() There is no way to recover permanently removed objects. However, in the case of human errors, such as uploading the same key to an existing object, the existing object is overwritten, hence removing it. So, it will definitely decrease the storage cost of future uploads, since S3 will keep only the latest object version. On Amazon S3, uploading an object with the same key will result in an overwrite. However, what if you were concerned about costs and decide not to use S3 Versioning? It can often be difficult to manage the costs of such a versioning operation.Īmazon S3 Versioning protects your data from accidental overwrites or deletions by keeping multiple variations of an object in the same bucket, which is really useful for security and data protection. While increased security with multiple versions and copies is a plus, the added storage costs of (purposefully) redundant data must be carefully considered. In the event that one version is harmed or corrupted, another is ready as a backup. Keeping multiple copies and versions of data is a tried-and-true security and data protection protocol.
