An example is provided to illustrate the behavior of encrypted volumes upon system

reboot. In this example, there are two encrypted disk volumes on the NAS:

DataVol1 is created with the option "Save Encryption Key" enabled.

DataVol2 is created with the option "Save Encryption Key" disabled.

Note:

For details on enabling or disabling the "Save Encryption Key" option, please

refer to the section on Encryption Key Management above.

After restarting the NAS, check the volume status. DataVol1 is locked, but DataVol2 is

unlocked and mounted. Since the encryption key is not saved on DataVol1, the

encryption password needs to be manually entered to unlock DataVol1. Please be

reminded that by saving the key on the NAS, data will only be protected in case of

stolen hard disk drives. However, there is still a risk of data breach if the entire NAS is

stolen as the data is accessible after the NAS is restarted. If the encryption key is not

saved on the NAS, the NAS will be protected against data breach even if the entire NAS

were stolen. The disadvantage is that the disk volume needs to be manually unlocked

each time the system restarts.
