Need a online backup feature  that does not block update operations   when online backup is
in progress.
--------------------------------------------------------------------------------------------------------

         Key: DERBY-239
         URL: http://issues.apache.org/jira/browse/DERBY-239
     Project: Derby
        Type: New Feature
  Components: Store  
    Versions: 10.1.0.0    
    Reporter: Suresh Thalamati


Currently Derby allows users to perfoms  online backups using SYSCS_UTIL.SYSCS_BACKUP_DATABASE()
procedure,  but while the backup is in progress, update operations are temporarily blocked,
but read operations can still proceed.

Blocking update operations can be real issue specifically in client server environments, because
user requests will be blocked for a long time if a 
backup is in the progress on the server.
