Yep.

To be a real 'warm' backup you need SSO, which requires 12.2S. Chances
are, you're probably not running this so the best you can get is RPR or
RPR+, which requires IOS to be booted on the slave RSP... Better than
nothing, but not ideal. I would highly recommend upgrading to 12.2(18)S
for the additional redundency features, or wait for 12.2SB which should
be out sometime this year (Rodney?)
