Versioning
The Versioning tab shows the current status (Đang bật / Enabled or Đang tắt / Disabled) and a list of what enabling it does:
- Every overwrite or delete of an object keeps the old copy as a previous version.
- Recover data that was accidentally deleted or modified.
- Keeping more versions increases storage usage against your quota.

Enable Versioning
Click Bật versioning (Enable versioning). The portal shows a confirmation dialog warning that storage usage may increase significantly.

Once enabled, the status becomes Đang bật (Enabled) and the button changes to Tạm dừng versioning (Suspend versioning).

Versioning has no on/off switch — each state shows a single action button: Bật versioning (Enable versioning) when it's off, Tạm dừng versioning (Suspend versioning) when it's on.
Suspend Versioning
Clicking Tạm dừng versioning (Suspend versioning) only stops new versions from being created going forward — versions already saved are not deleted. Simple Storage has no single button to fully turn off Versioning and wipe the version history.
To remove old versions entirely, go to the File tab, open a menu on an object and choose Xem phiên bản cũ (View old versions) to download or delete individual versions — see Manage Objects for details.
