Data expiry limit is too tight

[maphew]

Data expiry of 14 days is much too short. There are plenty of forms that I need to access only once a year but still need to re-use previous entries.

The current limit is in place in order to workaround "performance problems and javascript timeouts, particularly during version upgrades, and while searching encrypted data", which are indeed problems. But lets solve those a different way, or let us knowingly choose which suffering we're willing to put up with.

I agree with this. At the very least it should be 30 days, but in the past I would use forms saved for over a year.
