Tim:

I have two 3635s and backing up one and restoring into the other works
without any problem. Both iPAQs run exactly the same OS version and
build.

I do not know if this woud work on a 3900 but I would try... what the
worst that can happen...

Regards
Enrique

Is there a way to maintains two IPAQs to be identical with WinPilot? I
would like to set up a primary unit, with the second unit as a backup
in case the first one fails. I have found that just copying files does
not work. The settings files are not duplicated in this way. I have
two IPAQ 3950's.

Thanks,

Tim
