Tracy, First of all, cache mode and number of backups could be set only once - on cache start. So, if you know the size of your cluster you could set number of backups before cache start. But, I think it is not reasonable to set number of backups equals to number of nodes. If you need 100% high availability, just use replicated cache. But I would recommend to think about how many nodes at once can be lost? May be it is reasonable to set backups = 2? The more backups you choose - the more memory will be consumed by backup partitions and also grid will spend time in rebalancing data. What is your use case?
