Condition or Error

A full Xtrabackup backup has failed, and left the datasource's replicator offline.


  • A common cause of this failure is the existance of zero-length store-*.properties files in the backups/{serviceName}/ directory.


  • Simply remove any zero-byte store-*.properties files from the backups/{serviceName}/ directory and retry the backup.
