Locking a Snapshot

Lock a File Storage snapshot to prevent updates, moves, and manual deletions. Locks help protect resources against tampering.

Important

A lock on a snapshot doesn't prevent the system from automatically deleting a snapshot with an expiration date. Expiring snapshots are still deleted, even if they have a resource lock.

OCI resource locks include the following types:

  • Delete lock: Prevents deletion of the locked resource.
  • Full lock: Prevents update, move, and deletion of the locked resource.

You can only add or remove one lock type at a time, but both locks can be applied to a resource. For example, you might initially apply a delete lock, but choose to apply a full lock at a later time.

The user who places a lock is the lock owner. Any authorized user with lock privilege or users with global manage permission of the tenancy has the authorization to create and remove any lock in the tenancy. You can override or remove locks.

Required IAM Policy

To create locks, in addition to permissions to manage the snapshot, you need permissions to manage locks.

To lock a snapshot, you must have RESOURCE_LOCK_ADD permissions.

    1. Open the navigation menu and click Storage. Under File Storage, click File Systems.
    2. (Optional) In the List scope section, under Compartment, select a compartment.
    3. Click the name of the file system that you used to create a snapshot.
    4. On the file system's details page, under Resources, click Snapshots.
    5. Click the name of the snapshot that you want to lock.
    6. On the snapshot's details page, next to Resource Locking, select Add.
    7. In the Add Lock window, select the lock type and click Save changes.

  • Use the oci fs snapshot add command and required parameters to lock a snapshot:

    oci fs snapshot add --snapshot-id <snapshot_OCID> --type <lock_type>

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

  • Run the AddSnapshotLock operation to lock a snapshot.
