Case Study: 1
An enterprise customer has its main office in New York and branch offices in Dublin and London. The
VPN connectivity between each of the offices. The characteristics of each office arc described in the
following table.

A cloud-based backup solution performs backups in a continuous cycle A single individual at each
office is responsible to ensure that the backup jobs complete successfully. However, there are no
automated reports or verification of successful backups each day.
Requirements
You need to design a new backup strategy that meets the following customer requirements:
• Data that is identified as critical data must nave physically separate backups of the original
data.
• Non critical data must use a minimum amount of storage capacity.
• Each office must contain a local copy of the backup data.
• Each office must contain a local copy of the backup data from all three offices.

• The Storage capacity for the archived data must be minimized.
• The amount of bandwidth that is used for backup jobs must be minimized.
• All backup data must be encrypted at the highest available level.
• The performance impact on the data storage must be minimized during the backup window.
• The full cost of the solution must be calculated and presented before implementation.
