How to put CA into read-only mode

Hi,

We are performing DR failover testing and would like the EV and CA servers to be in backup mode.  It is straight-forward to put EV into backup mode.  We do have journaling connector installed and random sampling enabled.  Anyone know how to do it for CA without shutting down the CA Admin service?

The conern is we don't want the default sampling runs to happen at 8pm and 1am.  But we do want to bring up CA on the DR server to test.

I see there is an option to uncheck "Enable background processing of captures items".  Would that stop the pre-smapling and sampling from running at the prescribed times?

Thanks,
