Error after modifying the xml backup file Edited

[Suhas Patil [Riada]]

Hey guys,

I am getting error after modifying xml backup file.

"The file '/data/jira/import/backup.zip' is not a valid JIRA backup."

 I unzipped xml backup file, did some operations on entities.xml (followed Atlassian KB, https://confluence.atlassian.com/jirakb/project-import-fails-due-to-too-many-errors-747836945.html ), then zipped it again (#zip -r backup.zip backup/).. however while trying to import using new zip file, jira gives above error. 
I did notice that something is wrong with zip file format itself (zipinfo), looks like i am using wrong command to zip it.. what is the right zip command to create backup zip?

zipinfo for new backup.zip created gives this result..

[ec2-user@ip-xx-xx-x-xxx import]$ zipinfo backup.zip
Archive:  backup.zip
Zip file size: 144316013 bytes, number of entries: 3

3 files, 1976964518 bytes uncompressed, 144315421 bytes compressed:  92.7%

However the original backup file created by jira shows different info on zipinfo command,

[ec2-user@ip-xx-xx-x-xxx import]$ zipinfo backup_jira_se_stage_for_migration_13122017_backup.zip
Archive:  backup_jira_se_stage_for_migration_13122017_backup.zip

Found the problem. I was compressing entire folder containing 2 files instead of two files in one which was creating folder path as a third element making it a bad zip file.

Used some online tool for zip which creates it in proper format with fat and binary. 

Still couldn't figure what is the best was to compress on Mac.
