You can configure your miner to mine at a backup pool especially if you use poclbm.exe.
Run two instances of poclbm per GPU. Use the "f" command to give one pool priority over another. The lower the "f" value, the higher the priority.
-f30 to one pool will have priority over -f60 on a second pool.
This will split your GPU processing power to about 92% | 8% between the two pools. If one pool is idle, poclbm will automatically shift your mining power to the backup. This is even easier to setup and monitor using guiminer.
This has worked flawlessly for me and has always kept my GPUs at 100% through BTC Guild's growing pains.

How exactly do you do this? I've been trying to figure it out with no luck so far.

If you are using command line poclbm.exe (and an ATI/AMD based video card) try this:

Code:

poclbm.exe --user=username_workername --pass=password -o btcguild.com -p 8332 -d0 --verbose -v -w128 -f30

And then run poclbm.exe again with you other pool worker sign-on info.

Code:

poclbm.exe --user=username --pass=password -o other.pool.address -p 8332 -d0 --verbose -v -w128 -f60

If you are using GUIminer (adn ATI/AMD video cards) do this:

Go to "File" menu and choose "New OpenCL miner"
A pop-up windows will appear to name the miner. You can name it what even you want. I named it "Guild."
This will create a new tab in the GUIminer window. Click on it so we can start configuring.
In the "Server dropdown box, choose "BTC Guild."
In the Username box, type in your username_workername. Fill in your password in the password box.
In the Device name, choose your GPU. If you have multiple GPUs, they will be listed in there. They are numbered starting with 0. You will also see your CPU as a usable device. (This is a hint that you can use your CPU to mine, but it will slow your system to a crawl.)
In the "Extra Flags" box you can type in:

Code:

-v -w128 -f30

You can tweak these numbers to try to get as many Mhash/sec as you can.
Remember to go back to the "File" menu and "Save Settings"

Now, repeat these steps again. This time using a different pool. When you get to "Device" just use the same device again.
In the "extra flags" box, just use -f60 or any higher number.

The main point is to use two miner per GPU. If you have 2 video cards, setup 4 miners.

If you found this helpful and feel generous, a gratuity would be appreciated at: 1JJjL5nxzBfjFjJWoviU9mzrY3fQKxJfvV

Again, thank you for the help, it will be rewarded. Is there anywhere I can find what these flags mean exactly? I mean, I can put all this in, but I'd like to know what the -v -w and -f are for. Also, I assume the higher number -f takes precedent correct? So I'd set the btc guild hire, but if I wanted to fall back to solo mining it'd be set lower?
