Question
Scenario 1:
Refer to the scenario. A large publicity-traded motion picture exhibitor that is a leader In digital and 3D cinema deployments orepates 233 theaters and more than 2,200 screens in small to mid- sized 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 dally 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 infrascructure which runs VmWare VSphere 5 on HP Bladesystem c7000 enclosures and BL46Oc 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 disasterrecovery site (150miles)
- retaining more backup data in smaller disk space -increasing
efficiency, reliabillity 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
- inproved management of external audits
The company has asked that you create multiple solution proposals and prioritize one when you return for a presentation. How does an HP StoreOnce Backup solution meet the customer IT and business needs?
Options
- Aeliminates the need for tape backups for long-term archiving
- Bmultiplies the data, which is then replicated to a remote location
- Cbacks up the data via a WAN link
- Dprovides a bandwidth-effective replication to remote sites

Why each option
The question, likely referring to a modern disk-based backup solution with deduplication that replaces physical tape transport, highlights its ability to provide bandwidth-effective replication to remote sites. This effectiveness stems from significantly reducing the data volume before transmission.
While disk-based solutions can serve as long-term archives, they do not inherently eliminate the need for tape backups if tape is specifically mandated for certain archiving requirements, although they often replace it.
A deduplicating backup solution reduces data, not multiplies it, and the term 'replicated to a remote location' describes a process, not the core function of multiplying data.
While such solutions can back up data via a WAN link, this choice describes a method of backup, not the specific benefit of being 'bandwidth-effective' which is a key advantage of deduplication for WAN replication.
Modern backup solutions with data deduplication, like HP StoreOnce, are designed to reduce the size of backup data significantly. This reduction makes the subsequent replication of data to remote sites highly bandwidth-effective, as less data needs to be transmitted over the WAN link, overcoming the limitations of physical tape transport.
