Documented steps
Set a bucket default lock (also enables object locking on an existing bucket since RELEASE.2025-05-20T20-30-00Z): mc retention set --default GOVERNANCE "30d" ALIAS/BUCKET
Apply a compliance lock to an object: mc retention set compliance 30d ALIAS/BUCKET/object.csv
Apply to a specific version: mc retention set --version-id VERSION MODE VALIDITY ALIAS/PATH
Apply to all versions: mc retention set --versions MODE VALIDITY ALIAS/PATH
Known gotchas
MODE must be 'governance' or 'compliance' and VALIDITY is required - Nd for days (30d) or Ny for years (1y).
--bypass is only valid in governance mode and grants changes to users holding s3:BypassGovernanceRetention.
With versioning enabled, retention applies to the latest version unless --version-id/--versions is given.
Retention and legal hold can apply to the same object simultaneously; legal hold overrides retention, so a legally-held object stays locked even after the rule expires.
