My main pool had an outage recently, so I've decided to set up backup pools for the first time. I had read in another post that an extra miner can be set up using the same device, at a lower aggression setting. When the main miner goes idle, this second miner gets to use the resources and start mining. I decided to try this, and found the ideal settings for me. Maybe this will be a good starting point for someone else in need of a backup.

Main miner:
phoenix -u http://username.workername:workerpass@pool1.com:8344/ -k phatk DEVICE=0 VECTORS AGGRESSION=11 BFI_INT WORKSIZE=256 FASTLOOP=FALSE

Backup miner:
phoenix -u http://username.workername:workerpass@pool2.com:8344/ -k phatk DEVICE=0 VECTORS AGGRESSION=5 BFI_INT WORKSIZE=256 FASTLOOP=TRUE


I was surprised how much of a difference the fastloop setting has on low-aggression miners. With fastloop=false, my rate on my 5830 was 268mh/s. With fastloop=true it went up to 289mh/s.

The only drawback so far, is that the backup miner never really stops mining. It chugs along using a few mh/s for my backup pool at all times. Still, it doesn't seem to be reducing my overall output which is good.

Yeah I started doing this last week using GUIMiner. I wish I had known about it when I was starting out... I chose BTCGuild as my pool since it had a high hashrate and zero fees but I unfortunately began mining just before their DDOS and server issues.

I set a couple of machines to mine, went away for a few days and when I got back I found out they were sitting idle most of the time.
