 Description  « Hide
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.
