Question about Redundancy Size

Earlier I tried to increase the size of the redundancy on my instance, and either I haven’t really done it correctly, or there is a certain maximum that these can be set to.

In order to make things play better for myself, I’d like to have more redundancy for instances which I feel are valuable to me, which also have some problems with overloaded servers. For example often can’t fully serve the videos to us in a smooth way.

I have the three strategies enabled, and set for 25GB for the redundancy size, for each. I’m not really concerned that they haven’t been increasing in actual amount used, but rather that the total of unused, and used, continues to be 10GB for each strategy. Did I miss something?
