Behavior of immutable snapshots

Japanese

We are considering introducing QNAP NAS as a countermeasure against ransomware, and we are currently conducting operational tests with a demo unit.

We are using QuTs hero h6.0.0.3459.

We took an immutable snapshot of the shared folder.

We confirmed that snapshots cannot be deleted from FileStation6.

However, when deleting the relevant shared folder from Storage Manager, the shared folder is deleted along with the immutable snapshot.

Is it possible to prevent the deletion of a shared folder if it has valid immutable snapshots with an active retention period?

If there are any settings that should be configured, I would appreciate your guidance.

Hello.

Regarding the Immutable Snapshot feature, we have been considering and planning several adjustments from both design and control perspectives for some time now.

As for your comment about the current behavior where deleting a shared folder also deletes the immutable snapshot, this has already been identified as an issue to address. In future designs, this action will not be permitted. Users will only be able to delete shared folders after either completing a series of safety checks and operations, or waiting until the immutable snapshot protection period has ended.

This adjustment is scheduled to be released around the end of the year. Please stay tuned for upcoming QNAP feature updates.

Thank you very much for your continued support of QNAP.
