This document discusses backup strategies for data security, including file-based backup and incremental backup. It also explores the use of cloud backup strategies and their benefits. Additionally, it provides insights on how to protect yourself from spam activities and offers tips on identifying and reacting to spam messages.

1) The main objective of backing up data on the computer system or servers is to restore
it at a time of lost or corrupted due to any sort of virus or Trojan attack (Brewer,
2016). There are many types of backup strategies where two significant strategies are
detailed below –
 File-Based Backup/Full Data Backup – It is one of the most common backup
technique which includes creation of replica of all the data into an external
drive or disk. In this backup strategy, the data is back up within a single disk,
however, it takes much time to do a complete backup with this strategy in
comparison with others.
 Incremental Backup – This backup technique is used by people where
differences of data are backed up, which is dissimilar from the last backup.
This also leads to an advantage for the user as it only copies small amount of
data than full data backup and thus it is both time and cost efficient.
Use of cloud backup strategies –
 To store or backup any data and information, cloud backup is preferred by
many people as secure and safest platform (Harnik, Pinkas & Shulman-
Peleg, 2010). It gives many extra benefits and security and provides user to
access their data from anyplace in the world. It is also known by its other
name i.e. online backup as it back up the information with the help of
public network handled by many service providers.
In case of any issue, cloud-based backup helps the users to get quick
recovery of data at any time. Moreover, it is also backed by greater
security regulations and measures.
2) Spam activities involve the use of false internet accounts to send inappropriate
messages to a legitimate user. These sorts of messages are sent in big numbers
considering many basic intentions such as phishing, promotion, dispersion of
malicious links, fake reviews, malware attacks and on-click baiting (Sanz, Hidalgo &
Perez, 2008). To help conquer these issues, several security techniques and
mechanism can be used in order to be protected from these spam activities.

 Look out for long range informal communication spam
Span is rising continuously with the proceeding of pervasiveness of informal
communication among all sorts of public (Calise, De Rosa & i Marin, 2010). New
stage of social building methods makes it hard to identify honest or fraudulent emails.
These bottlenecks in align with the trust amid long range informal communication
associations allow spammers to attain more personal understandings in relation to
their goals and hence, make more substantial damage.
As per Cloudmark, a cyber-security firm reveals that around 34% of UK
grown-up uncovered that they received SPAM emails connected with informal firms
somehow. Considering spam messages, it is harder to differentiate conventional spam
and emails (Delany, Buckley & Greene, 2012). Sometimes, informal companies are
being misused by spammers in order to spread spam messages. Acknowledging all
these things, you need to ensure that it is the individual you “become a close
acquaintance with” on informal enterprises instead of just focusing on increasing a
companion check.
 Know how to react legitimately
It is important to consider whenever one noticed spam that not to react to them. As
per reports by Cloudmark, it was found that all those who reacted to spam messages, 25% of
them received more spams consequently. One can report the message to the hostile by
tapping the message or labelling it as a spam message. In addition, one can also buy smart
protection from an organisation which will caution the user if anyone is planning to take on
fake exercise.
 Not to tap or join any message that is non-trustable
In fraudster portfolio, spreading malignant messages becomes one of their important
approaches. It is now very easy for them to hide the message they are sending with a main
web-connect link that is needed to tap upon. Considering all things, tapping on the specific
web link or message in the mail will go specifically to the website on the browser to run out
the activity the email is requesting.

When done, one will be realized easily that whether it was an honest web link or
phishing site that copy out malware on system. It is important to consider the comparable the
alert for messages sent from respective email address in referring with client address book, as
it looks more authentic.
 DO up-to-date all security programmes and other PC frameworks
It is important to ensure that all system security programmes are getting regular
update from their regular source. These include antivirus software, defenders, and internet
security programmes (He, Chan & Guizani, 2015). It is also important to do most recent
update of the system or platform on which all applications are running. This will help in
fixing compatibility issue and also leading to prevent users from spam attack.
