Its perfectly adequate through 'n' speeds, but I would imagine that 'g' would be a bit slow. Do the initial back up through ethernet though as it would take some time due to the large file size.
To be honest if you use your computer at your desk alot it would make sense to get a firewire drive. i think wireless n has a theoretical maximum of 10 Mbps (not 100% on that) however any number of external factors could slow down that speed.
