I would suggest having a copy of the database on your iPad then use a sync system to sync your data when connected by to the server.
GoZync by seedcode https://www.seedcode.com/downloads/
Mirrorsync by 360Workds are a couple of options 360Works :: FileMaker Developers :: FileMaker Consultants :: FileMaker Pro Plugins
You can script Save A Copy As to get a backup, then insert the backup file into a container field, then export the file out of the container in FMGo, which would have to be done while you have internet access. You would still have the issue of syncing your data back to the server / cloud.
I was talking with seedcode about implementing their system, but unfortunately they can't get it done by next week when I need it, and it's a little beyond my personal capabilities.
I think I'm just going to have to collect the various copies my employees are working on and merge them myself. Not ideal but that's where I am. I was just wondering if there is an easier way to get a database onto the hard drive of the iPad using Filemaker Go/Cloud, other than going through iTunes.
Drop box, iCloud, Google Drive, email attachments
Can all be used to wirelessly copy files to an from an iOS device.
