An Error occurred while we are taking the xml backup.
Error: "There was a problem backing up data for the null plugin"
But the XML backup file created with above error. when we are going to restore it gives the below Error.
Error importing from zip file: "/var/application-data/jira/import/2016-Sep-30--0100.zip". Error: archive is not a ZIP archive
At location "/application-data/jira/export\" we have observed a folder with name "corrupted" i attached this folder I hope it will help out you to diagnose the exact problem.
Please investigate and resolve the issue.
Thanks
