Disk Volume Information
Behavior of Encrypted Volume Upon Reboot
In this example, we have two encrypted disk volumes on the NAS.
The first volume (Single Disk Drive 2) has been created with the option Save
Encryption Key enabled.
The second volume (Single Disk Drive 5) 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.
Disk Volume Status
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 server is stolen. The
disadvantage is that you have to unlock the disk volume manually on each
system restart.
Encryption Key Management: New Password, Save Encryption Key, Export
To manage the encryption key settings, login the NAS as an administrator and choose
Disk Management > Encrypted File System.
