Backing up and restoring databases

Derby provides a way to back up a database while it is online. You can also restore a full backup from a specified location.

While the backup is in progress, update operations are temporarily blocked, but read operations can still proceed.

• Roll-forward recovery
  Derby supports roll-forward recovery to restore a damaged database to the most recent state before a failure occurred.
