Answer 2

Answer:

Remote backup systems provide a wide range of availability, allowing the transaction processing to continue even if the primary site is destroyed by a fire, flood or earthquake.

Data and log records from a primary site are continuously backed up into a remote backup site.

One can achieve ‘wide range availability’ of data by performing transaction processing at one site, called the ‘primary site’, and having a ‘remote backup’ site where all the data from the primary site are duplicated.

The remote site is also called ‘secondary site’.
