Backup Guidelines
Backup Disc
Disk Storage and recovery
By Cam Merritt http://www.ehow.com/facts_6012687_differences-between-backup-recovery-discs.html
Many PC manufacturers don't include recovery discs with new computers. Instead, all the information that would be on the disc is stored on a separate partition of the hard drive, known as a recovery partition.
Backup discs contain copies of important and often irreplaceable files such as photos, manuscripts, financial records, music and videos. You can make backups discs yourself to preserve valuable files in the event of a system failure or physical damage to your computer.
Important data should be backed up regularly, and backup discs should be stored in a safe place that is separate from your computer.

What's inside backup discs?
EXERCISES TO UNIT 3:
| Data retention | defines the policies of persistent data and records management for meeting legal and business data archival requirements. A data retention policy weighs legal and privacy concerns against economics and need-to-know concerns to determine the retention time, archival rules, data formats, and the permissible means of storage, access, and encryption. Fiscal factors, such as tax laws and general auditing requirements, also condition data retention. |
| De-duplication | Removing duplicate records from a database, especially when two or more databases have been merged to form a single larger list. Network data de-duplication is used to reduce the number of bytes that must be transferred between endpoints, which can reduce the amount of bandwidth required. |
| Virtualisation | simulation (or making virtual) of some effect or condition on a computer Virtualization simplifies IT so that small and medium companies can more effectively utilize their storage, network and computing resources to reduce costs and respond quickly. |
| Storage virtualisation | is a concept and term used within computer science. Specifically, storage systems may use virtualization concepts as a tool to enable better functionality and more advanced features within and across storage systems. Storage virtualization is the amalgamation of multiple network storage devices into what appears to be a single storage unit. Storage virtualization is often used in SAN (storage area network), a high-speed subnetwork of shared storage devices, and makes tasks such as archiving, back-up, and recovery easier and faster. Storage virtualization is usually implemented via software applications. IBM offers a variety of storage virtualization solutions to meet the needs of companies of all sizes. |
