So you have no backup?

 Unfortunately, the backup I had were a week older compare the data that was lost. It happened that I am performing the backup  scheduled automaticallyevery Sunday (Weekend). I am rely on the daily snapshot incase some data need to retrieved afterwards. All the recently file created and modified were lost.

Important data should never be stored on just the one device.

Attached External USB Hard Drive capacity 8GB for weekly backup.

Do you recall which firmware you were running?

 RN 6.4.0 the latest firmware

What disks were installed? What was the capacity of your volume?

Toshiba 1TB x 4 Drive

I can see you only opened a support case today, but did not register your device. It would be helpful if you registered the NAS as that is one of the first things support will ask you to do.

I had a plan to register after few days all the data were placed from our old windows file server but I am running out of time when the incident was happened. Actually we been only using this device just for three weeks but sorry to say unlucky choice to have this facilities.

Any positive option that I can recover the data, it is a disaster for us to choice a trusted brand but no solution for a such unexpected incident.
