The usual idea about backup is to do it while the device you do it on still works. Then you have your files when it breaks down.
When somebody forgets to backup (some people do, even when it's as easy as using the cloud) and needs the data after an event like you experienced, we enter the realm of 'recovery', which is quite another thing.

My droid Razr phone keeps crashing randomly! I've had it only a year and it's giving me issues. Last night I picked it up and it wouldn't turn on, no matter how long I held down the button. I plugged it in and it told me I had 47% battery so I assumed it just crashed. Later on last night, I put it down and when I came back, it had crashed again. This bothered me but I was tired so I went to bed. When I woke up, it had crashed again. I'm beginning to get frustrated and I plug it in again. Turns on like usual and it doesn't seem to have problems for a while. So I'm playing a game and once again, it crashes. When I plug it in, it shows me my phone is dead, which makes no sense, seeing how before it crashed I had 94%. So I figure I will try to back up my phone so when I plug it in, it will only let me back up my pictures (Something I don't need) and all i really want to back up is my music, games, and contacts which aren't on the cloud. It doesn't open up my music folders or anything. Only my pictures. Do somebody know what's wrong with my phone and can tell me how to fix it? Or at least tell me how I can back up my files?
