ZZIIPPEE Bank is one of the fastest growing banks in India with more than $1200$ branches across the country and manages $$200$ billion in assets. Handling millions of dollars of banking transactions per day, its customers depend upon the integrity and availability of their banking data.

The Bank has to comply with a new cybersecurity regulation that requires financial institutions to have DRPs and BCPs to prevent massive losses during a disaster or data breach.

The Bank realizes that it has to move its IT operations to a less risk$-$prone area. Furthermore, it has to separate its production and disaster$-$recovery facilities by a large distance to be immune to a widespread disaster. But it has to do this in such a way that it would lose no data in the event of a production data$-$center disaster.

The Bank plans to consolidate its multiple data centers into a single production data center with remote protection. It plans to have their disaster$-$recovery site in another state with an equipment configuration that is an exact mirror of the production facility.

The Bank plans to keep the backup data$-$center$$s databases in synchronism with the production data center via asynchronous replication.

However, the Bank estimates that it might lose up to $30$ seconds of data following a production$-$site outage because of the asynchronous$-$replication solution. To solve this problem, the Bank can use a third minimal disk$-$only $$bunker$$ site closer to the production site to act as a second up$-$to$-$date data repository.

The Bunker is a secure ex$-$military compound, purpose$-$built to protect data from every potential threat including nuclear attack. All infrastructure is kept $30$ meters below ground, behind concrete walls three meters thick only accessible through two$-$ton steel doors and guarded $24/7.$ It is flood proof, bomb proof, and immune to EMP and digital$-$eavesdropping.

You are required to complete the following tasks to assist the Bank to implement a comprehensive business$-$continuity, backup, recovery, and archiving solution.
