Hi All,

Today I had an Interview with one of the product companies. Below is the scenario they have asked.

There is a DataCenter in HongKnog, Due to current protests in the country they want to backup/copy the entire servers data in the data center to a different location in FrankFurt.

For SImplicity he asked me to design a solution to backup one Server in HongKong datacenter to other server in FrankFurt DC.

• The server will have Peta Bytes of data
• It could contain Databases, files, Images etc.,
• While transferring Data transactions hould not be lost like there could be data related to CreditCards, banking etc

My Solution:
I said we could have different services that will read data from the server and send data to a HashMap in between to prevent loss of data since we are sending in HTTP Traffic.

The interviewer asked more detail design, all the component, services involved in this design which I could not answer.

Could Someone point to a right thoughts.
