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 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 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 rerun could take p 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
(150 miles)
– 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.
