Governance mode: Use Governance mode if you want to protect objects from deletion by most users for a pre-set retention period but also want some users with special permissions to have the flexibility to change retention settings or delete objects. Users with the s3:BypassGovernance Retention permission can override or delete retention settings in governance mode.
Compliance mode: Use Compliance mode if you have compliance data retention requirements. You should only use Compliance mode if you do not want any users to be able to delete objects within the preset retention period.
