QNAP TVS-472XT 4-Bay NAS Enclosure - Manual (Page 176)

Action Description
Remove Remove the volume or LUN from the NAS and delete all of its data from the cloud
space.
Important
If QTS is unable to connect to the cloud service provider, then the
volume or LUN will be removed from the local NAS but its data
might be left in the cloud space.
Safely Detach Removes the volume or LUN from the NAS but do not delete its data from the cloud
space. The volume or LUN can be reattached to this NAS or another NAS later. For
details, see the following sections:
• Reattaching an Existing VJBOD Cloud Volume
• Reattaching an Existing VJBOD Cloud LUN
Important
• QTS moves all non-uploaded data in the write cache to the
cloud space before removing the volume or LUN. This process
may take a long time to complete.
• If it's not possible to connect to the cloud space, the detach
operation will fail.
Force Detach: QTS removes the volume or LUN from the local NAS and leaves its
data in the cloud space. If it's not possible to connect to the cloud space, QTS will still
delete the volume or LUN from the local NAS.
Warning
If Force Detach is selected, non-uploaded data stored in the
volume or LUN might be deleted.

volume or LUN can be recovered if it encounters an error. You can use these recovery points to restore the
volume or LUN to a previous state.
