Briefly explain the importance of doing backup in systems administration and explain in detail any three methods for performing backup!?​

Answers

Answer 1

Answer:

Importance of backup in system administration:

Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.

Three methods for performing backup:

Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the  disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go. Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.

What is the value of X when line 30 is executed in the program below:

20 X = X + 5
30 X = X/5 + X
40 X = X * 5
50 X = (X - 5)/5

this is for qbasic btw

any helpis appreciated pls only correct answers

Answers

Answer:

X = 12

Explanation:

The primary value of X is 5. In line 20 X = X + 5, which is saying the primary value of X ,5, + 5, this is going to return the value of X to now become 10. Now the primary value of X in the program has changed to 10.

In line 30 X = X/5 + X, keeping in mind that the new primary value is not 5 but 10. So now line 30 is saying X = 10/5 + 10. This return the value of X to be 12.

Answers

Answer:In order to swap elements of ArrayList with Java collections, we need to use the Collections.swap() method. It swaps the elements at the specified positions in the list.

Declaration −The java.util.Collections.swap() method is declared as follows

public static void swap(List <?> list, int i, int j)

where i is the index of the first element to be swapped, j is the index of the other element to be swapped and list is the list where the swapping takes place.

Explanation:

import java.util.*;

public class Example {

  public static void main (String[] args) {

    ArrayList<Integer> list = new ArrayList<Integer>();

     list.add(10);//0

     list.add(20);//1

     list.add(30);//2

     list.add(40);//3

     list.add(50);//4

     System.out.println("Original list : " + list);

     Collections.swap(list, 4, 0); // swapping element at index 3 i.e. 50 and index 1 i.e. 10
