What is Dbvisit Standby?
Dbvisit Standby automates the synchronisation of a hot standby database at a remote or local location. A standby database is like having an online hot backup of your database instantly available 24x7. There is no need to restore in the event of a disaster (which is very time consuming), as there is instant data recovery and database recovery. It is possible to switch over to the standby database in a matter of minutes to allow business continuity in an emergency. No other software is required to replicate the primary database onto a separate standby server. 
An overview of Dbvisit Standby is presented in figure 1.
