Description:
When BusinessEvents Persistence mode is turned on and the "Do not recover on startup" option is not selected, BE takes a snapshot of the working memory (a checkpoint) at specified intervals. If the system goes down, after it comes back up, BusinessEvents restores the working memory to its state as of the last checkpoint.

Any changes in BE working memory after the last checkpoint and before the shutdown will not be persisted and recovered from the DB files, but if JMS is used for channels, BE will get all the unacknowledged messages back when it restarts.
