Q:

Can the data at UseMachineKeyStore be backed up and recovered?

I have the following code:
const int PROVIDER_RSA_FULL = 1;
const string CONTAINER_NAME = "Example";
CspParameters cspParams;
cspParams = new CspParameters(PROVIDER_RSA_FULL);
cspParams.KeyContainerName = CONTAINER_NAME;
cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cspParams);

As I understand it, a keypair is generated automatically and then becomes the referenced key pair using the KeyContainerName "Example".
I'm using a dedicated host. I want to be sure that our hosting company are aware of this information being important, making sure it's backed up, and not losing it, because then all the information I have encrypted and stored in a database will be useless.
I can't find any word in MSDN about how it works in the background.

A:

The Key containers are stored in the
  file system. The directories are
  Machine Keys: documents and
  settings\all
  users\application\data\microsoft\crypto
  and subdirectories.
Be aware that you can not "reuse"
  those keys on other machines or if you
  are going to rebuild your machine!
