Comment 1 for bug 1815919

Thank you for the report.

First of all, at every DB upgrade, Lifeograph saves a backup copy of the last version with a name that equals the original name plus version number. So, your pages (entries?) should be safe unless you deleted that backup file.

Second of all, this kind of problems are very important as preservation of user data is of topmost priority. So, I am really interested in diagnosing and fixing this problem.

The dropped pages should not be random. Especially if you lose the same pages when you upgrade again. There should be a pattern, a common property among the pages that are lost.

Probably the file contains sensitive data and you cannot share it. So, can you do the following:
1) Create a copy the pre-1.5 version of the diary file.
2) Open the copy on Lifeograph 1.4 and delete all the entries except for those that get deleted.
3) Edit the contents of the remaining entries to remove any personal or sensitive data but make sure that entries still have some content, they should not be completely empty.
4) Create a new backup copy of the new file.
5) Open the latest copy in v1.5 to make sure that the entries are still getting deleted on upgrade.
6) Share the not upgraded copy with me to investigate.
