During upgrade to the latest version of JIRA, 5.1.1, we used the provided upgrade.bin which automatically performed a back-up.
During the back-up process it seems the disk got full which caused the entire virtual machine (VMWare) to crash leaving the .vmdk corrupt. So far all attempts on retrieving data have been unsuccessful.
The problem we are facing is of course massive loss of data, and the question is how we can rebuild the database to a more recent time than the available back-up? We have most of the emails which are automatically generated available, can they somehow be parsed into the service?
