Protecting against total machine failure


You can use a live backup to provide a redundant copy of the transaction log that is available for restart of your system on a secondary machine in case the machine running the database server becomes unusable.

A live backup runs continuously, terminating only if the server shuts down. If you suffer a system failure, the backed up transaction log can be used for a rapid restart of the system. However, depending on the load that the server is processing, the live backup may lag behind and may not contain all committed transactions.
