Summary
This document addresses a concurrency error in Bamboo during the backup process which results in the backup failure with the error message Unable to find Plan present in the logs.
Environment
Bamboo 7.0 and above.
Diagnosis
The following error can be found in <bamboo-home>/logs/atlassian-bamboo.log file:
1
2
ERROR [scheduler_Worker-10] [XmlMigrator] Problems occurred while exporting
com.atlassian.bamboo.migration.stream.MapperExportException: java.lang.IllegalStateException: Unable to find Plan for PROJECT-PLAN-1
Cause
The cause of this failure is that the Expiry process which is running in the background, can be deleting some plans, log files, and artifacts, and it may be running at the same as the backup process. The backup tries to backup these files which in fact may have already been deleted.
Solution
The recommendation is to run the expiry and the export in different timeframes to avoid this kind of concurrency problem. Change the backup schedule to a different time by following this documentation: Specifying a backup schedule.
