Coin Wallet organization

[altcointalk14]

I am looking for some advice on how to best set my wallets.  Let's say I have 5 rigs and solo mining 12 different altcoins.

Do I need to install 12 wallets on each of the 5 rigs?  Don't think this is the most efficient way to do this.  Any suggestions?

I think you can install only one wallet per coin, and later you can make the connection of the rigs to this wallet. I want to say, the 5 rigs will go to the same wallet.

Put all your wallets on one machine.. Mine on LAN using rpcallow=192.168.1.IP of your mining machine in coin.conf file

Set

url ="192.168.1.IP:rpcport" in the cgminer conf file

Is it good/acceptable practice to put all your wallets on a mining rig or should we store our wallets on a separate machine?

Also, what does everyone think about using Google drive to constantly backup wallets?
