4. Confirm the settings and click "Finish".

data before creating the encrypted volume. Click "Yes" after data backup.

Encryption key management

To manage the encryption key settings, login the NAS as an administrator and go to

"Storage Manager" > "Volumes" > "Actions" > "Encryption".

There are three options to manage the encryption key:

Change the encryption key: Enter your old encryption password and the new

password. (Please note that after the password is changed, any previously

exported keys will not work anymore. The new encryption key needs to be

downloaded if necessary, see below.)

Download the encryption key file: Enter the encryption password to download the

encryption key file. With this option, the encryption key can be saved as a file. The

file is also encrypted and can be used to unlock a volume, without knowing the real

password (see "Locking and unlocking disk volumes manually" below.) Please save

the encryption key file in a secure place!

Save the encryption key: Save the encryption key on the NAS to automatically

unlock and mount the encrypted disk volume after the NAS restarts.

Locking and unlocking disk volumes manually

To lock a volume, login the NAS as an administrator. Go to "Storage Manager" >

"Volumes". Select a volume to be locked and click "Actions" > "Encryption" > "Lock this

Volume". Click "Yes". To unlock a volume, login the NAS as an administrator, go to

"Storage Manager" > "Volumes", select a volume to be unlocked, click "Actions" >

"Encryption" > "Unlock this volume". Choose either to enter the encryption password, or

use the encryption key file exported previously. Click "Apply". If the encryption password

or the key file is correct, the volume will be unlocked and become available.

Verifying encrypted disk volumes

To verify that a disk volume is encrypted, login the NAS as an administrator. Go to

"Storage Manager" > "Volumes". The encrypted disk volume will be shown on this page,

with a lock icon under "Status". The lock will be shown as opened if the encrypted

volume is unlocked. A disk volume without the lock icon under "Status" is not encrypted.
