  management and emergency services
• Procedures to follow with the computer equipment, such as
  equipment shutdown and removal of files
• Evacuation procedures for employees
• Return of people to premises and under what circumstances

Question 5

Emergency Plan

Answer 5

Staff information
Contact information
Recovery information

Question 6

Back Up Plan
Types

Answer 6

Full backup - every bit of data is backed up (the alternative is a
partial backup)–
Types of partial backups
* Incremental or differential backup (one tape for full back up, one tape for
incremental back up) - only data that has changed since the last backup is
saved.
* Selective backup - only selected files are backed up

Question 7

What should be considered

Answer 7

When
What
What quantity
How long
Where

Question 8

When

When - Backup

Answer 8

Frequency of change and Importance of data

Question 9

What backup media should be used

Answer 9

The quality of the data
The level of automation involved
Speed of recovering the backed up

Question 10

What Quantity of Data should be backed up

Answer 10

Time taken to perform backup
Effectiveness depends on file management

Question 12

How long should you keep the backup

Answer 12

Possibility of faulty files if limited media is repeatedly used
The Ability to fully document and carry out a backup schedule particularly if it is complexed

Question 13

Where should backup be stored

Answer 13

Level of saegty within the organisation
Level of off-site location security

Question 14

Types of backup media

Answer 14

Tapes
Removable har drive
CD/DVD
Mirror site
Cloud

Question 15

Media

Answer 15

What the data is saved to

Question 16

Backup media Requirements

Answer 16

• Selection criteria:
  –Read/write speed
  –Capacity
  –Lifetime of recorded data
  –Robustness (e.g. against scratching, magnetic field)

Question 17

Restoration Plan

Answer 17

Consists of specific procedures for restoring
the full information capacity of the
organisation. It covers both hardware and
software replacement

Question 18

Verifying complete recovery of data

Answer 18

Can the replacement software read and process data that has been stored?
Can new data be created and saved?
Can the replacement system cope with the workload?
Are walware scanners, firewalls and continuous backup programs working?
Are new servers connecting to workstation reliably?
Has all data been restored or recreated?
Can normal business resume?

Question 19

Test Plan

Answer 19

It is important of know that all parts of the
DRP will work. The test plan consists of
information that contains a number of
simulations or a variety of disasters and
different recover needs.

This will also include the testing of the backup.
It is important to know that the backup
actually works and time these simulations occur

Question 20

Disposal

Answer 20

Copy obsolete data to secondary storage (e.g. DVD) and delete the original
data.
Files that are no longer used, but have to the kept for audit, legal or
research purposes are usually archived.

Question 21

Archiving

Answer 21

Backing up = copy data, keep the original.
Archiving means removing the files from the every day file storage system
to an archiving system
Archiving can bet stored on a number of storage medium, simular to that
of back up medium.
