Object Lock
Object Lock is a feature that enables you to apply Write-Once-Read-Many (WORM) protection to objects, preventing them from being deleted or modified for a specified duration. It provides robust, programmable safeguards for storing critical data that must remain immutable.
Note: Once a bucket is created without an object lock, you cannot add it later.
Use cases
Data Preservation: Protects critical data from accidental or malicious alteration and deletion, ensuring integrity and consistency.
Regulatory Compliance: Aligns with European regulations such as GDPR, MiFID II, and the Electronic ID and Trust Services (eIDAS) regulation, maintaining records in an unalterable state.
Legal Holds and Audits: Facilitates legal holds and audits, meeting requirements for transparency and accountability.
Modes
Object lock can be applied in two different modes:
Governance: Allows specific users with special permissions to override the lock settings. Ideal for flexible control.
Compliance: Enforces a strict lock without any possibility of an override. Suited for regulatory and legal mandates.
These two lock modes require configuring the duration for which the object will remain locked. The period can range from days to years, depending on the object's compliance needs.
For the objects under Governance mode, the retention configuration can be modified or removed by including a specific header variable in the API request. However, for objects in Compliance mode, reducing the retention period or removing the retention configuration is not possible.
Note: Under Object Lock or Object Hold, permanent deletion of an object's version is not permissible. Instead, a deletion marker is generated for the object, causing IONOS S3 Object Storage to consider that the object has been deleted.
However, the delete markers on the objects are not subject to protection from deletion, irrespective of any retention period or legal hold on the underlying object. Deleting the delete markers restores the previous version of the objects.
Legal Hold
An additional setting called Legal Hold can place a hold on an object, enforceable without specifying a retention period. It could be applied both to objects with or without Object Lock. The Legal Hold will continue to be applied till manual removal even if the object’s retention period for Governance or compliance mode is over.
Manage Object Lock
Note: Object Lock configuration can only be enabled during the initial creation of a bucket and cannot be applied to an existing bucket.
When a bucket is created with Object Lock enabled, you can set up Object Lock configurations. These configurations determine the default mode and retention period for newly uploaded objects. Alternatively, Object Lock settings can be explicitly defined for each object during its creation, overriding the bucket's default settings.
Web console
Prerequisite: Make sure you are creating a new bucket for which you want to enable Object Lock.
1. In the DCD, go to Menu > Storage > IONOS S3 Object Storage.
2. Create a new bucket with Object Lock enabled.
3. From the Buckets list, choose the bucket for which Object Lock is enabled and click Bucket settings.
4. Click Object Lock to manage these settings on the bucket.
Result: The object lock is successfully applied on the bucket upon creation.
IONOS S3 Object Storage API
Use the Object Lock API to manage the Object Lock configuration on the specified buckets.
Command-line tool
Use the CLI to manage Object Lock.
Limitations
The following are a few limitations to consider while using Object Lock:
Versioning will be automatically enabled in addition to Object Lock.
Once the Object Lock is enabled during bucket creation, both Object Lock and Versioning cannot be disabled afterward.
When you place or modify an Object Lock, updating the object version's metadata does not overwrite the object version or change its Last-Modified timestamp.
A bucket with Object Lock enabled cannot be chosen as a source for replication or tiering, but it could be a destination for replication or tiering.
In the Compliance mode, an object is immutable until its retention date has passed. It is not possible to disable this mode for the object or shorten the retention period. This setting could not be changed either by the bucket owner or IONOS.
