If by backup route you mean a feasible successor then once EIGRP has lost the primary route it should be failry instantaneous because it has no need to qurey any other routers.

Have a look at this white paper on EIGRP -

http://www.cisco.com/en/US/tech/tk365/technologies_white_paper09186a0080094cb7.shtml#feasibleandreported

Note the sentence on the part i have linked to about losing a route and having a feasible successor -

"The network converges instantly..."
