Scenario 1:
Refer to the scenario.
During a follow-up meeting with your customer, you learn that there is an additional business requirement to limit the total downtime of data center systems to 72 hours, and no more than 24 hours of data can be lost. The IT department indicates that they have an existing 2-hour response time SLA with their business users for critical systems.
What should you use for their RTO and RPO when designing a new backup solution?
(Case Study):
A large publicity-traded motion picture exhibitor that is a leader In digital and 3D cinema deployments operates 233 theaters and more than 2,200 screens in small to midsized communities in 35 states around United States. They rely on MS Exchange Server 2010 for email, MS SQL. Server 2010 for analyzing data about movies and theater-goers, and MS Excel 2010 for crunching numbers. The company runs nightly incremental backups and a full weekly backup that consists of close to 7TB of data which takes up 72 hours to complete. The quarterly backups add an additional 7 TB of data.
Tapes are inventoried and transported from the main data center to the disaster recovery site 150 miles away. The process of transporting tape cartridges to and from the Disaster Recovery site requires hours of daily work.
The company currently relies on an aging robotic tape library and a process that takes the nightly backup tapes of site every morning. Additionally, the company keeps an inventory, and if a restore is necessary, they have to retrieve the tapes from the DR site and transport them to the main data center site. They have a 7 year data retention plan, and the tapes are expensive and not always reliable. Given the company’s current system, if a full weekly backup fails over a weekend, the re-run could take up to 10 hours, even if just one job failed.
The company has deployed an virtualized server infrastructure which runs VmWare VSphere 5 on HP Bladesystem c7000 enclosures and BL460c servers interconnected with HP virtual Connect Flex-10 10Gb Ethernet modules as well as several HP ProLiant DL380 servers. The company top four IT improvements goal are as follows:
- replacing the aging robotic tape library
- enabling replication of backed up data from the main data center to the disaster recovery site (150miles)
- retaining more backup data in smaller disk space
- increasing efficiency, reliability and ease of System administration.
Moreover the company’s top thee business benefit goals are as follows:
- increased confidence in disaster recovery
- Minimal disruption by backup during regular business hours
- improved management of external audits.
The company has asked that you create multiple solution proposals and prioritize one when you return for a presentation.
