----------------------------------
Summary: Fuseki2 backups
Key: JENA-895
URL: https://issues.apache.org/jira/browse/JENA-895
Project: Apache Jena
Issue Type: Bug
Components: Fuseki
Affects Versions: Fuseki 2.0.0
Reporter: Andy Seaborne
Assignee: Andy Seaborne
Fuseki2 backups aren't properly wrapped in a transaction, causing the exception
below for TDB (if the dataset has moved to transactional - there is a timing
hole around backup+first use in a recently started server).
