S3 Versioning and Lifecycle Policies

We often store important files in S3. But what if a file is accidentally deleted or overwritten? What if we need older versions?

• AWS S3 offers powerful features to protect your data and manage it efficiently.
• This lesson introduces S3 Versioning for data recovery and Lifecycle Policies for cost optimization.
• These tools help ensure your data is safe and that you're only paying for what you need.

• S3 Versioning keeps multiple versions of an object in the same bucket.
• When enabled, every time you modify or delete an object, S3 creates a new version instead of overwriting the old one.
• This acts like a safety net, allowing you to recover from unintended deletions or overwrites.

Each version of an object has a unique version ID.
