I want to write this article simply because once too many times i have lost data. Sometimes i lose data because i thought i backuped everything on my phone but actually i didn’t and i did a reset. Sometimes i think that my hard disk wouldn’t spoil. Apparently that all isn’t true. So i do urge everyone to do a backup. Nowadays i use a nas and a raid 5 for my data. Granted it is not a full proof plan and the other day i just had to recover my data because the firmware of my raid failed me. But still i was able to get back my data albeit it took a long time to do so.
