I progress slowly...but I have a new error.
Here is my code :
//create the graph
neo = new EmbeddedGraphDatabase(CONSTANTS.GRAPH_PATH);
graph = ObjectGraphFactory.instance().get(neo);
for (String datasource : new String[]{"nioneodb", "lucene"}) {
neo.getConfig().getTxModule().getXaDataSourceManager()
.getXaDataSource( datasource ).keepLogicalLogs( true );
}
graph.close();
neo.shutdown();
/*
* here, I put my code to copy the content of the graph directory to
the backup directory
**/
//open again the graph
neo = new EmbeddedGraphDatabase(CONSTANTS.GRAPH_PATH);
graph = ObjectGraphFactory.instance().get(neo);
/**
* I create the backup graph
**/
EmbeddedGraphDatabase neo = GraphJo4neo.getGraphDatabaseService();
EmbeddedGraphDatabase backupGraphDb = new
EmbeddedGraphDatabase( CONSTANTS.GRAPH_BACKUP_PATH );
IndexService backupIndexService = new
LuceneIndexService( backupGraphDb );
Backup backup = new Neo4jBackup( neo, backupGraphDb,
new ArrayList<String>()
{
{
add( "nioneodb" );
add( "lucene" );
}
} );
try {
backup.enableFileLogger();
backup.setLogLevelDebug();
backup.doBackup(); // /!!\ : ERROR HERE
} catch (IOException e) {}
backupIndexService.shutdown();
backupGraphDb.shutdown();
But I obtain this error :
java.lang.RuntimeException: Missing log entry in backup source: [10]
in resource [nioneodb]. Can not perform backup.
