I would strongly advise against this. Secure cloud storage is only secure until it isn't. Storing seeds/private keys online somewhere makes retrieving it more convenient, but also opens up another attack vector. Storing them physically makes them impossible for hackers to get to. Robbers can still get them (only if they know about them too), sure, but if one enters your home, you likely have bigger problems.
Once the computer is reformatted, any recovery efforts will no longer work. My way is to print it out and keep it where you know it. Every care will always bring good effect to your property.
