What is the best way to export all JIRA data (projects, issues, ...)? I saw that there is an API and a plugin mechanism which probably can provide all the information. But what is the easiest way to export the data? Does it work out of the box or do I have to implement a plugin?
Generally, there are two main approaches to backup your JIRA data. The first one is to back up your database in which JIRA info is stored. The second one is to use the “Backup Data to XML feature”, which is a JIRA feature. Personally, I prefer the second one, because it can be restored to any database engine (MySQL, MSSQL, etc). In addition, as far as it is Xml, it can be compressed to a great extent.
