Summary

 < Day Day Up > 

Only a backup system can protect against deleted files, natural disasters, or theft. Backup processes copy important information to magnetic tape or other permanent storage media.

The main factor driving backup hardware selection is the relationship of performance to cost.

Unattended backups can significantly reduce administrative costs.

Backups must be performed using a very disciplined, scheduled regimen.

A full backup is a complete backup of the entire server or client.

A partial backup can be either incremental or differential. An incremental backup copies all files that were changed after the last backup. A differential backup copies all files that were changed after the last complete backup.

The grandfather-father-son (GFS) scheme is the most commonly used tape rotation scheme.

Backed up data needs to be moved regularly to an offsite facility in case something happens to the main facility.

A disaster recovery plan involves a regular backup rotation, a proven restore process, offsite storage of media, and procedures for re-creating the affected environment.
