RAID 1 For Android?

[Guest]

I couldn't think of a better title to explain my question. I recently bought an S7 Active and also a microSD card. I'm wondering if it would be possible to somehow force the phone to save photos, videos, documents, etc to internal storage AND the microSD card at the same time by default, just in case one gets corrupted I can have a second copy. Is this natively supported or can it even be done? I'm not very good with phones so sorry if this has an obvious answer; Google wasn't much help. Thanks!

I'm sure it's somehow possible, but I don't know of any ways. I do have an alternative for you: Google Photos. It's free and gives you unlimited photo storage. Set it up to where whenever you take a photo, it'll automatically back it up to the cloud.

Hmmm, let's see where do I start.  First you'd need a completely custom kernel for your device with the md RAID compiled in.  As certainly the stock kernels do not incorporate RAID as there's no need for it on a mobile device.   Of course, it goes without saying that you'd need root access to your device to accomplish this. 

 

Once you've built a kernel with the RAID, you'd also need to incorporate the RAID management tools into the android distribution.  This would probably mean figuring out the framework for cross-compilation.  Then, and only then, would you be able to get into a shell, and actually create this RAID volume. 

 

Impossible?  Nope.  But you have to have a decent understanding of Android architecture, Linux kernel compilation, and how to work with all of the associated debugging and recovery steps.

Thanks for the advice, but I actually have a home server that all my stuff is backed up to. I mainly would like this feature for even more redundancy because I'm paranoid.

So in other words not a chance in hell, at least with my limited knowledge of Android. And to be clear I wasn't really talking about an actual RAID set up, I was more using that as what I'd like to do in principle. But if that's basically the only way then I guess I have my answer. I'll leave this up for a bit in case someone has a second opinion, otherwise I'll mark yours as correct and move on. Thanks!

Late reply, but if you use Tasker, you can make a profile to make copies of things on your internal storage to your external one by checking if that file already exists in a certain directory on your external storage. It would take a bit of study on how to work with some variables and commands, but it can be done.

You could try this app.

First one I found after a 15 second Google search. I'm sure there are other apps that do the same thing and are more extensive, just have to do a little digging for yourself.

I appreciate you looking but that isn't what I'm after. I've actually looked into that app and installed it for a few days but it didn't accomplish what I set out to do. Thanks anyway though!
