You work as a design specialist at Certkiller .com. Certkiller .com collects sales bills as *.jpg images and processes them into text. The text is stored in a database with a link to the image to maintain the chain of custody. At present, images occupy 3 terabytes and the text database occupies 200 gigabytes. Growth is linear with requirements expected to double in two years. Full backups are taken weekly and incremental back ups are taken daily in a single-threaded backup environment using one, LTO-II tape drive. The Service Level Agreement (SLA) specifies an RTO of 48 hours to restore claims processing at a warm recovery site. The At Time of Disaster is 24 hours.
When will the RTO be exceeded?

A.
2 months

B.
8 months

C.
12 months

D.
22 months

E.
It is already exceeded

Explanation:
LTO2 speed is roughly 144GB/hour. So 24 hour window (based on time of disaster meaning that amount of time will have past before restore operations will have started) will be 3.456TB total. Currently is 3.2TB, the difference is 0.256TB. Data growth is 0.125TB per month, so 2 months. A is the answer.
