What it means
Versioning can preserve prior object states after overwrite or deletion. Lifecycle rules can move data to different storage classes or remove it according to policy.
Why it matters
These features support recovery and cost control, but misconfigured rules can retain sensitive data too long or delete the only recoverable copy.
Practical focus
- Align lifecycle rules with legal, business, and recovery needs
- Protect versions from ordinary deletion and compromise
- Test restoration from archived classes
- Monitor failed transitions and unexpected retention
Common mistakes
- Treating versioning as a complete backup strategy
- Applying deletion rules before validating dependencies
- Ignoring cost from retained versions
