What this card says
What it is
Versioning keeps old copies of a file when it is changed or deleted.
A lifecycle rule moves or deletes old files automatically.
Example
Move logs/ to cheaper storage after 30 days. Delete old versions after 60 days.
Why it matters for security
With versioning, a file deleted by mistake or encrypted by ransomware can be restored.
For key backups, Object Lock stops even an admin from deleting them quickly.
| Action with versioning ON | Result |
|---|---|
| Upload same key again | New version; old version kept |
| Delete without version ID | A delete marker hides the object; data still there |
| Delete a specific version ID | That version is gone permanently |
| Suspend versioning | New uploads get no version; old versions remain |
