Beware! Unless your application makes full use of transaction processing, dbpause may well split in the middle of a business transaction. If you were, for example, moving funds between two client accounts, restore of the backup may have the money in both accounts (bad news) or neither account (a healthy profit until someone spots it!). As far as I am aware (and I have put much effort into this one) there is no safe way to backup the system without at least briefly getting all the users to a quiescent state. The easiest way to do this is to get them to log out across the dbpause and mirror breaking operation.
