To meet

Scarlet Price’s requirement for data security, team “Endurance” has considered

the need for off-site storage as part of its backup and recovery strategy.

Discuss other

factors that should have been considered when developing a backup and recovery

strategy for the youth community centre. (8 Marks) Jun 2012

When

developing a backup and recovery along with where the storage would be kept,

Scarlet Price should also

consider who will be carrying out the backup- they can allocate one of the

employees to ensure that adequate backup is carried out. They would also

need to consider what

media it will be stored on, and as it is a smaller organisation an external

hardware could be used in order to store the backup because of the fact that it

is a smaller organisation this media is in the finance of the organisation.

The type of back up along with how often it should be carried out would need to be considered.

The youth centre could carry out an incremental back up twice a week in which new data is stored along

with the previously old data which had been backed up before

Explain

what is meant by :

i)

Adaptive

Maintenance (2 Marks)

-

When

there’s a change in the environment, the system would need to be altered in

order to fit this change. Eg. Legislation/VAT

ii) Corrective

Maintenance (2 Marks)

-

This

would be carried out if the system contains bugs or errors such as if the

system is moving slow

iii)

Perfective

Maintenance (2 Marks)

-

This will

be used in order to enhance the features based on the feedback from clients-

eg. If they want to change the colour of the layout in the system

ICT

systems can vary in size from those used by small, one-person businesses to

those used by large, multi-national organisations.

Discuss how the

size of an organisation may affect the backup and recovery procedures that it

uses. (15 Marks) Jan 2013

The size of an

organisation is essential when planning the backup and recovery procedure in

which it will use. Initially, they may carry out a risk analysis in which the

business would ensure that everyone is aware of the possible threats which can

take place in the system, this may more likely be carried out by a large

organisation rather than a small organisation. In the case that there is a

threat to the system, whether external or internal, downtime for a large

organisation is unacceptable as it could result in the loss of money for the

organisation. Therefore large organisation would use recovery sites such a hot

site , in which there are already equipment and electricity at the site ready

to be used in the case of a threat. Smaller organisations may use recovery

sites such as a cold site which the site has no furniture or equipment and

everything would need to be moved from the current site to the cold site.

Smaller organisations can also make use of reciprocal arrangement in which they

along with another small organisation has a formal or informal agreement to make

use of each other’s system in the case that there are problems within their

own. Smaller organisations are more likely to use these methods rather than a

hot site as it would be too expensive to ensure that electricity and new

equipment are already stored along with the fact that they can afford a

downtime in the system while the larger organisations would not be able to do

so, therefore they have to ensure that they have a site ready to be used in the

case of outage. Larger organisations are more likely to have a contingency plan

in which they would plan the recovery in the case of various different outage

such as electricity, complete/partial loss of telecommunications and other

losses such as loss of maintenance services. They larger organisation would

more likely to plan how to recover from such loss as they cannot afford any

downtime in the case of an outage etc. Smaller organisations may have some of

the factors planned, however having all of the factors planned in a contingency

plan is less likely. Both organisations, would have a backup strategy in which

they will highlight who will carry out the back up, for a larger organisation

the backup is more likely to be carried out by a set person such as an ICT

technician, while a smaller organisation the responsibility of backup will just

be allocated to an already hired employee. For a larger organisation it is more

likely for them to carry out a full or incremental backup daily, so that they

have all the data if needed, whilst a small organisation would not need for

often backups but rather a couple days in the week for backup to take place
