This document provides an overview of backup and restore processes in Linux. It discusses that backups have two main purposes - to recover from data loss through deletion or corruption, and to recover older versions of data according to retention policies. It also outlines the steps to backup files using tar to create an archive, compress it with gzip, transfer it to another system, and then extract the files. These include using tar and gzip commands like tar -cvf, gzip, scp, and tar -xvf. Maintaining regular backups is important as data loss can threaten companies, and backup is a key system administrator duty.
A closer quick understanding of different backup technologies and pros and cons backup & recovery,ntbackup,types of backups, windows backup path so far, differential backup, incremental backup, full backup, mirror backup. If you have have anyqueries please contact me at jabvtl@gmail.com
The tar command stands for tape achieve, which is the most commonly used tape drive backup command used by the Linux system. It allows to quickly access a collection of files and placed them into a highly compressed archive file commonly called tar, gzip and bzip in Linux.

Chapter 8: Common Forensic Tools
Overview
In this chapter, you'll learn more about:
· Explore disk imaging tools, forensic software tool sets, and miscellaneous software tools
· Understand computer forensic hardware
· Assemble your forensic tool kit
The first steps in any investigation nearly always involve old-fashioned detective work. As a forensic investigator, you need to observe and record your observations first. Once you start examining media contents, you'll need some tools to help you find and make sense of stored data.
Forensic investigators and computer examiners need several different types of tools to identify and acquire computer evidence. Some evidence is hidden from the casual observer and requires specialized tools to find and access. In this chapter, we'll examine a sampling of some common and popular tools available to carry out computer forensic tasks.
Disk Imaging and Validation Tools
After identifying the physical media that they suspect contains evidence, forensic investigators must make sure media is preserved before any further steps are taken. Preserving the media is necessary to provide assurance the evidence acquired is valid.
Chapter 3, "Computer Evidence," and Chapter 4, "Common Tasks," both emphasize the importance of copying all media first and then analyzing the copy. It's usually best to create an exact image of the media and verify that it matches the original before continuing the investigation. It's rare to examine the original evidence for any investigation that might end up in court. For other types of investigations, however, forensic investigators might perform a targeted examination on the original evidence. For example, assume the job is to examine a user's home folder on a server for suspected inappropriate material. It might be impossible or extremely difficult to create a mirror image of the disk drive, but the disk can be scanned for existing or deleted files while it is in use. Although examining media while in use might not always be the best practice, informal investigations use this technique frequently.
To Copy or Not to Copy?
Whenever possible, create a duplicate of the original evidence, verify the copy, and then examine the copy. Always invest the time and effort to copy original media for any investigation that might end up in a court of law. If you are sure your investigation will not end up in court, you might decide to analyze the original evidence directly. This is possible and desirable in cases where copying media would cause service interruptions.
Your choice of tools to use depends on several factors, including:
· Operating system(s) supported
Operating system(s) in which the tool runs
File systems the tool supports
· Price
· Functionality
· Personal preference
The following sections list some tools used to create and verify media copies. Some products appear in two places in the chapter. That's because several products play multiple roles. This section lists several products ...
The tape Industry began in 1952 and the disk Industry in 1956. In 1952, the world’s first
successful commercial tape drive was delivered, the IBM 726 with 12,500 bytes of capacity per
reel. In 1956 the world’s first disk drive was delivered by IBM, the Ramac 350 with 5 megabytes
of capacity. Though no one knew it at the time, two key and lasting events linking disk and tape
for the foreseeable future had just occurred

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

BACKUP AND RESTORE IN LINUX
In information Technology, a backup or the process of backing up is masking copies of data
which may be used to restore the original after a data loss event.
Backups have two district purposes.
The primary purpose is to recover data after its loss, be it by data deletion or corruption. Data
loss is a very common experience of computer users. 67% of Internet users have suffered
serious data loss.
The secondary purpose of backups is to recover data from an earlier time, according to a user-
defined data retention policy, typically configured within a backup application for how long
copies of data are required.
Backup is the most important job of a system administrator, as a system admin it is your duty to
take backup of the data every day.
Many companies have gone out of the market because of poor backup planning.
The easiest way to backup up your files is just copying. But if you have too many files to backup,
copying and restoring may take too long time and it is not convinient. If there is a tool that can
put many files into one file, the world will be better. Fortunetly, 'tar' is used to create archive
files. It can pack files or directories into a 'tar' file. It is like Winzip in windows, without much
compression.
The gzip program compress a single file. One important thing to remember about gzip is that,
unlike tar, it replaces your original file with a compressed version. (The amout of compression
varies with the type of data, but a typical text file will be reduced by 70 to 80 percent).
3. If there is any issue at setup or connection contact support@k21technologies.com
To backup the file using tar
To backup the file using tar Syntax is
#tar -cvf <destination and name to be > <source file>
Check the size of tar file by using du -h <filename> command #du -h /opt/etc.tar
Now apply gzip on tar file and check the size
To apply gzip on a tar file, the syntax is #gzip <file name>
#gzip /u02/etc.tar
Now check the size of the file
4. If there is any issue at setup or connection contact support@k21technologies.com
Transfer the file to other system and remove gzip and tar from it and check the size on every step
Let's Transfer the file to other computer using scp
#scp /u02/etc.tar.gz 192.168.2.10:/root/
Untar the file and check for the size of the file / directory
tar -xvf <file name>
