Option for double write of S3 objects for extra durability

[purplefox]

S3 claims a durability of 11 nines (99.999999999%) - which allegedly means you can expect to lose 0.000000001% of your objects per year. If you store billions of objects, the probability of loss becomes non-negligible.

We should allow an option of double writing S3 objects - so, we write two copies of each object to the store, so that, if one is lost, we still have the other. And, hopefully, the chance of loss of both objects would be vanishingly small.

This would apply to Master record

Hey, can I take this up if not being actively worked upon ?
