A Backup scenarios
In this appendix
This Appendix describes two scenarios: one for company XYZ and one for company ABC. Both companies plan to enhance their data storage systems. Their current backup solutions are described along with the inherent problems. Solutions are then proposed to alleviate the problems and to meet the future data storage needs of both companies.
Considerations
In both cases, the following considerations must be taken into account when formulating a company’s backup strategy:
•How critical system availability (and backup) is to the company
•The need to keep the backed up data at a remote location in case of disaster.
•The level of business continuance. This includes the recovery and restore plan for all critical systems.
•The security of backed up data
The need to guard premises to prevent unauthorized people from entering. This also includes safeguarding all relevant data against unauthorized access with physical access prevention and electronic password protection.
•The type of data that needs to be backed up
The company’s data can be divided into categories like company business data, company resource data, project data, and personal data, each with its own specific requirements.
•Performance aspects for backups and restores
•Network and system topology
Determine which systems can use what network links and what transfer rates are possible.
•Time window
