This document discusses data integrity and how to preserve it. It defines data integrity as the completeness, accuracy, and consistency of data throughout its lifecycle. Data integrity ensures the validity and accuracy of data and is different from data security which protects data. Threats to data integrity include human error, transfer errors, security issues, attacks, and hardware problems. Tools are recommended to check for duplicate files and remove them to maintain integrity. Backups are also important to prevent data loss. The document outlines features of data integrity like accessibility and reliability of data. It provides a checklist for input and data validation, duplicate removal, and access controls to preserve integrity.

Maintaining Data Integrity

2. What is Data Integrity?
• Data integrity is the overall completeness, accuracy
and consistency of data.
• Data integrity refers to the reliability and
trustworthiness of data throughout its lifecycle. It can
describe the state of your data—e.g., valid or
invalid—or the process of ensuring and preserving
the validity and accuracy of data.
• Servers have critical data and unique
configurations that must be protected.

3. What is the Difference Between Data Integrity
and Data Security?
• Data integrity is not to be confused with data security.
• Data security refers to the protection of data, while data
integrity refers to the accuracy of data.
• Common threats that can alter the state of data
integrity include:
• Human error
• Unintended transfer errors
• security errors
• cyber attacks
• Compromised hardware

4. Feature of Data Integrity.
• So how do you know when your data has integrity? You have to
look at the following features:
• Retrieve and accessibility: It’s important to have accurate data
in the proper locations at the right time when anyone is working
on projections, a deal, or presentation.
• Reliability – Having reliable, consistent business metrics
against company goals and the competition is what will take an
organization to the top.

5. Checklist to preserve data integrity.
• Use the following checklist to preserve data integrity and
minimize risk for your organization:
• Validate Input: When your data set is supplied by a known or
unknown source you should require input validation. That data
should be verified and validated to ensure that the input is
accurate.
• Validate Data: It’s critical to certify that your data processes
haven’t been corrupted. Identify specifications and key attributes
that are important to your organization before you validate the
data.
• Remove Duplicate Data: Sensitive data from a secure
database can easily find a home on a document, spreadsheet,
email, or in shared folders where employees without proper
access can see it. It’s prudent to clean up stray data and remove
duplicates.

6. Tools for preserve data integrity.
• Smaller companies without a dedicated staff will find that these
tools can assist them clean up duplicate files on a hard drive or
cloud.
• Clone Files Checker
• Duplicate Images Finder
• Easy Duplicate Finder
• Duplicate Cleaner
• Ccleaner
• DoubleKiller
• WinMerge

7. Server Duplication Features
• For Windows Servers: Use the Data De duplication feature to
clean up cloned files. Also try the File Server Resource Manager
to remove stray files.
• Back up Data: In addition to removing duplicates to ensure data
security, data backups are a critical part of the process. Backing
up is necessary and goes a long way to prevent permanent data
loss.
• Access Controls: What’s often overlooked is physical access
to the server. The most sensitive servers should be isolated and
bolted to the floor or wall. Only individuals who access should
have an access key – ensuring that the keys to the kingdom are
kept secure.

8. Data Backup
• Protecting data against loss, corruption, disasters (human-
caused or natural) and other problems is one of the top priorities
for IT organizations.
• The term backup has become synonymous with data protection
over the past several decades and may be accomplished via
several methods.
• Backup software applications reduce the complexity of
performing backup and recovery operations.

9. Types Backup
• Full backups
• The most basic and complete type of backup operation is a full
backup. As the name implies, this type of backup makes a copy
of all data to another set of media, such as a disk or tape. The
primary advantage to performing a full backup during every
operation is that a complete copy of all data is available with a
single set of media.
• However, the disadvantages are that it takes longer to perform a
full backup than other types and it requires more storage space.

10. Types Backup
• Incremental backups
• An incremental backup operation will result in copying only the
data that has changed since the last backup operation of any
type. An organization typically uses the modified time stamp on
files and compares it to the time stamp of the last backup.
Backup applications track and record the date and time that
backup operations occur in order to track files modified since
these operations.
• The benefit of an incremental backup is that it copies a smaller
amount of data than a full. Thus, these operations will complete
faster, and require less media to store the backup.
