Hey there, thanks for participating in the Beta and thanks for posting! At this time, there isn't a way to back messages up in DIGITS, but that's great feedback. I'm not sure if this functionality would be added in the future, but we can definitely pass this along. In the interim, if you have individual messages that contain important data, you could try taking a screen shot to save the details as a photo - I know that's not a permanent fix, nor does it maintain the "threading" aspect of a message conversation; but it's the best solution I can think of for case-by-case retention.
This thread was the product of our fantastic collaborators during DIGITS Beta! As many terms have changed and bugs have been exterminated since the Beta launched, the information here may no longer be accurate.
