GCGA Ch. 9 Protecting Data with Backups (ST)

Question 1

Offline backups

Answer 1

use traditional backup media such as tapes, local disks, drives in a NAS, and even backup targets within a SAN. Online backups are stored in the cloud.

Question 2

Traditional backup methods

Answer 2

include full, full/differential, full/incremental, snapshot, and image strategies. A full backup strategy alone allows the quickest recovery time. Full/incremental backup strategies minimize the amount of time needed to perform daily backups. Full/ differential backup strategies minimize the amount of time required to restore backups.

Question 3

Backup best practices

Answer 3

A copy of backups should be kept off-site and should be kept far enough away so that a disaster impacting the primary site doesn’t impact the backups. It’s important to consider the distance between the main site and the off-site location.

Question 4

Backup location

Answer 4

The location of the data backups affects data sovereignty. If backups are stored in a different country, the backups’ data is now subject to the laws and regulations of that country. Backups should be encrypted to protect the sensitive data they contain from compromise should the backup media be lost or stolen.
