Does PS Plus help prevent savegame corruption?

I recently encountered a crash in Battlefield 4 and decided to take a break. Out of curiosity, I browsed my PS4's storage to see what's stored inside, and noticed that only the Battlefield 4 savegame was described as corrupted. Upon launching the game anew, I had to acknowledge the loss of all of my progress thus far.

In an unrelated case, I decided to subscribe to Playstation Plus. I know that my PS4 will automatically upload savegames to the cloud, as long as I am subsribed to PS Plus, but I was wondering if it also does so for corrupted savegames.

Obviously, if it does I'll have to make sure to disable the auto-upload feature.

So, does my PS Plus subscription help me avoid corrupted savegames, or not?

Yes, it's likely to help as long as the savedata is uploaded to PS Plus before the corruption happens. It's a good idea to disable the auto-upload feature if you're worried about corrupted data being saved to the cloud.

I haven't experienced any savedata corruption, but I assume that corrupted savedata would be uploaded to the cloud too as the cloud wouldn't actually know if the data is corrupted. Hopefully, the PS4 safeguards against this by not uploading corrupted data to start with.
