Question

Restore Mendix Data Loss

0

Does Mendix store additional backups to apps? I recently reverted an app to a previous version, which then lost a lot of data that was in the database. The ‘daily’ backup for today was created moments after the revert was made, so there is no backup available to me that would have the data. Does Mendix have the ability to revert an app to a previous date/time (i.e to this morning?)

Matthew,

I feel your pain, having done something similar once (ok, maybe twice) before. Unfortunately, the best you can do is the nightly backups that Mendix generates, unless you or another developer happened to make a manual backup, or downloaded a backup with some of the deleted data, at some point.

Sorry I couldn’t provide you with a better answer to this one,

Mike

When you update an app always make a backup copy. So when you do revert make a copy first of the current situation and then revert back to the previous version with that backup. Then at least you have a local copy with the latest data and can do an analyses of what is missing and how to get that data to the previous version. Not an easy task by the way unless your app is small.
