Encryption Verification
To verify the disk volume is encrypted, login the NAS as an administrator. Go to "Storage
Manager" > "Volume Management". You will be able to see the encrypted disk volume,
with a lock icon in the Status column. The lock will be open if the encrypted volume has
been unlocked. A disk volume without the lock icon in the Status column is not
encrypted.
Behavior of Encrypted Volumes upon System Reboot
In this example, we have two encrypted disk volumes on the NAS.
The first volume (Single Disk Drive 1) has been created with the option "Save
Encryption Key" enabled.
The second volume (Single Disk Drive 4) has been created with the option "Save
Encryption Key" disabled.
After restarting the NAS, check the volume status. The first drive has been unlocked and
mounted but the second drive is locked. Since the encryption key is not saved on the
second disk volume, you have to manually enter the encryption password to unlock it.
Saving the key on the NAS will protect you only if your hard drives are stolen.
However, there is a risk of data breach if the entire NAS is stolen as the data is
accessible after restarting the NAS.
If you select not to save the encryption key on the NAS, your NAS will be
protected against data breach even if the entire NAS were stolen. The
disadvantage is that you have to unlock the disk volume manually on each system
restart.
Encryption Key Management
To manage the encryption key settings, login the NAS as an administrator and go to
Storage Manager" > "Encrypted File System".
There are four options to manage the encryption key:
Change the encryption key
Download the encryption key file
Remove the saved key
Save the encryption key on the NAS
