I recommend you display a great big message saying "do not disturb!" while the restore occurs. You can't actually block the user, for example, from the home key, or the power key...
So I'd suggest transactionalizing things as much as possible. Read a set of related files (e.g. for one app) all at once to temporary names, then quickly rename the old ones, rename the temporary ones with their permanent names, and delete the old. Then, if you receive a Pause event, delete your temporary files. If you ever encounter renamed old files, you have a partial update. That should be very rare, but you can roll back by restoring the old files to their original names, deleting any new files in their place -- or renaming them to a recovery name inn case the application has done something with the partial update in the meantime. You can minimize the chances of that by checking for the restore progress on reboot, and verifying consistency at that point.
