A company needs to maintain and verify backups at a secondary site to meet the following requirements: RTO of two hours, RPO of 12 hours, four weeks retention. Which of the following backup copy job configurations meets these requirements?
A.
Periodic backup copy job, scheduled for a two-hour interval, with 56 restore points to retain
B.
Periodic backup copy job, scheduled for a 12-hour interval, with 56 restore points to retain
C.
Periodic backup copy job, scheduled for a two-hour interval, with 112 restore points to retain
D.
Periodic backup copy job, scheduled for a 12-hour interval, with 112 restore points to retain
Correct one is B --> You need a 12-hour RPO with 4-week retention (2 copies per day with 28-day retention = 56 restore points). RTO is not specified in any response, therefore the 2 hours of RTO in the question must be discarded.
1 backup/12h - 56 points => 2 points per day => 28 days
