Summary

If a user has a large Jira production site, during a sandbox copy they may run into a generic error message that results in a failed copy:

Unable to copy some data
You can try to copy data from production to sandbox again...

There is no documented limitation on sandbox import size: Sandbox limits.

Current Workaround

• Atlassian Support needs to review the internal logs:

  message: Archive for manifest file mpri:file:org:<org-id>:<file-id> with size X gb exceeds limit 10 gb

• Atlassian Support then needs to apply a feature flag to bypass the limit during the import

Recommendation

• Automating the disabling of the import limit to allow larger customers to copy data from production to sandbox
• Provide a clearer error message if the sandbox copy failed due to size limit
