CMJ - *is not a valid file name*

Problem

Users are unable to create snapshots using Configuration Manager for Jira (CMJ) on Jira Data Center The snapshot wizard fails on the first screen with the error:
“is not a valid file name”.

Solution

This issue occurs when the user lacks write permissions to the export directory:
/var/atlassian/application-data/home/export/

To resolve:

  1. Ensure the snapshot folder exists and is writable:

    sudo mkdir -p /var/atlassian/application-data/home/export/ sudo chown -R jira:jira /var/atlassian/application-data/home/export/ sudo chmod 755 /var/atlassian/application-data/home/export/

  2. Retry snapshot creation using a lowercase name with underscores (e.g., test_snapshot_01).
