Recently, I have received the help requests from a number of friends regarding the data recovery. Some of them are wipe all of phone data by accident. Some of them lost some of data due with the data store failures. There is no easy solution to recover the data. Thus, please back up your data. My photo will back up automatically to my NAS via an app. Moreover, all of my important will be sync with my NAS too. I got some super important even having a cloud back up. In addition, I won't be just use the NAS as the backup storage. I still got some external hard disks to backup nas too. I got at least two back up copy of my data, and my NAS is running with two hard disks in the mirror mode. So, Back Up, Back Up, Back Up
