We already do back up data on our end, all data is backed up nightly in separate hosted location.
To back-up your data we currently enable you to export all your app data into excel. In this way you can copy the exact data you need.
All your data are programmatically accessible via the Podio API: https://developers.podio.com/ If you can not use the API in house, we can advice on finding a developer to do it for you.
Our partners provide back-up via the API, I recommend to check these extensions on Back-up for Podio:
