What is your Problem in understanding the Word "Backup"?
Translation for you:
A Backup is a File or Set of Files thadt contains the Data of your
Business critical Informations.
It should not be Archived on the same place, the same House or the same
Room.
A Replication Database has nothing to do with a Backup, it works only
for Failover if the Primary
Database has a Mailfunction.
A good Backuptool is needed if you have Databases with sizes over 1
Terrabyte. The common
Backup methods wont Work with Online Productiondatabases and without the
Problem of Datalosses,
this is only a Way for small and Mediumsize Databases, not for Hugh
Databases.
Keep in Mind: Backup is NOT Replication!
Write it down 100 times and maybe you understand
