Why should you store backup media offsite?

> To prevent the same disaster from affecting both the system and its associated backup media. Explanation: Backup media should be stored offsite to prevent the same disaster from affecting both the system itself as well as its associated backup media. For example, if your primary facility is destroyed by flood or fire, your data remains protected at an offsite location. Offsite storage does not significantly reduce the possibility of media theft because it can be stolen while in transit and while at the remote storage location. Offsite storage is not mandated by government regulation in the USA. Offsite storage does not improve the efficiency of the restoration process because additional time will be spent maintaining the backup media at the remote location.

Match each backup method on the left with the correct description on the right.

Backs up all files (even those that have not changed). > Full Backs up every file that has changed since the last full or incremental backup. > Incremental Backs up every file that has changed since the last full backup. > Differential Compares the data found in the last full backup with the current content and uploads only the changes. > Synthetic Explanation: The following are the appropriate descriptions of each listed backup method: - Full - backs up all files (even those that have not changed). - Incremental - backs up every file that has changed since the - - last full or incremental backup. - Differential - Backs up every file that has changed since the last full backup. - Synthetic - Compares the data found in the last full backup with the current content and uploads only the changes.

You have created a system image of Windows 11 on your laptop before updating several applications on your hard drive. The system image is stored on an external hard drive. After updating one of the applications, you are required to restart your laptop. However, during the restart, you receive an error message that the system is unable to reboot. You try to restore the system image from the external hard drive, but you are unsuccessful. Which of the following do you need to do BEFORE successfully restoring your Windows 11 system using the system image?

> Use a recovery disc to restore the operating system. Explanation: If you are unable to boot into Windows, you will be unable to restore a system image. You can, however, use a recovery disc to restore the operating system so that you can then restore the system image. Although you could set the BIOS/UEFI settings to boot from the external hard drive first, this would not impact the ability to restore the system image. Simply copying the system image to the Windows hard drive will not solve the issue, as the recovery needs to happen from an image on a separate source (such as an external hard drive). Even though you can copy the system image to a network computer, this will not solve the problem of not being able to access the image if the laptop cannot boot into Windows.

Which operating system uses the Time Machine backup program?

> macOS Explanation: The macOS operating system uses the Time Machine backup program. Windows, Android, and Linux use other backup apps or features (such as File History) to perform backup tasks.

Which of the following describes the grandfather backup in a grandfather-father-son (GFS) rotation scheme?

> A full backup that is stored offsite. Explanation: Most organizations create a strict rotation schedule for performing full and partial backups. One commonly used rotation scheme is the grandfather-father-son (GFS) backup type. The grandfather is a full backup that is completed once a month or so and stored offsite. It is not an incremental backup store offsite. The father is a full backup that is completed once a week and stored onsite. The son is an incremental backup that occurs daily and is kept onsite.

You work as the IT administrator for a small startup company. Lily's computer has two internal hard drives and runs Windows 11. She is concerned that she may accidently delete a personal file or that her primary hard disk may fail at some future time, causing her to lose her personal files. She has come to you for suggestions about how to protect her files. Due to the size and revenue of this startup company, resources are somewhat limited. Which of the following would BEST protect Lily's files?

> Back up her files using File History. Explanation: Windows 11 includes a backup service known as File History. With File History, only the data in a user's profile (such as personal files) is backed up. Lily could also add folders to a library to back them up using File History. File History does require a second disk for backup. This backup drive could be a second drive in a computer, a USB-connected drive, or a network drive. Lily could use this feature to back up her files from her primary drive to her secondary drive, or you could purchase an inexpensive USB drive that she could use to automatically back up her personal files to. With the limited funds available, buying a third-party backup software program probably isn't feasible at this time. Having Lily copy her files to a network share would work for files she creates, but counting on her to back these up on a regular basis is risky. Scheduled disk maintenance allows the system to diagnose and repair disk errors, not back up files.

As the system engineer for a large financial institution, you have decided to implement a backup system on all the Windows 11 laptops used by the financial consultants to ensure that critical customer data is securely stored. Your requirements for the backup system include: - Only customer data files created by the financial consultants need to be backed up. - Data backed up to a flash drive. - Backed up files must be uncompressed. - Include contact lists and desktop preferences. Which of the following backup solutions BEST meets your requirements?

> File History Explanation: File History meets all the requirements for the backup system you need, including only backing up personal data files, the ability to save the data to a flash drive, no compression involved, and the ability to back up profile files, such as contacts and desktop preferences. File Backup also meets several of your requirements. However, the backed up files are compressed before storage. System Image backs up the drives required for Windows to run. It does not focus on personal files created by the user. Differential is a backup method that backs up every file that has changed since the last full backup. This method is not a backup system you use to focus on backing up personal files.

You need to back up user data on a Windows 11 system. The computer has a single SSD storage device installed that contains both the Windows operating system (in C:\Windows) and user profile data (in C:\Users). You plan to do the following: - Use Backup and Restore to back up user data. - Run the backup automatically every night at 11:00 p.m. - Store the backups in the C:\Backups folder. - Include a system image in each backup. Will this configuration work?

> No, backups created with Backup and Restore can't be stored on the drive that contains the information being backed up. Explanation: The configuration in the scenario will not work because backups created with the Backup and Restore utility can't be stored on the same drive that contains the information being backed up. To fix this issue, you need to add a second hard disk or external storage device to the system. Windows 11 includes both the File History and Backup and Restore utilities. System image backups can be included within a scheduled file backup.

An administrator configures the Time Machine application on macOS computers and develops scripts that use the tar command on Linux computers. Which of the following best practices is the administrator following?

> Scheduled backups Explanation: The Time Machine application on macOS computers and the tar command on Linux are used for backups. While Time Machine and tar can restore disk files, scheduled disk maintenance is usually performed to maintain disk and file system integrity. Patch management involves updating operating systems and applications, not performing backups. Driver and firmware updates involves updating the middleware that interfaces with internal and external devices, not performing backups.

You need to specify hich location File History should use to store backup data. Click the Control Panel option you would use to do this.

> Select drive Explanation: Use the Select drive option to specify the location that File History will store backup data. The Restore personal files option retrieves previous versions of files protected by File History. The Exclude folders option works to prevent certain folders from being protected by File History. The Advanced settings option is used to clean up old backup versions. From Advanced settings, you select the appropriate cleanup interval from the Keep Saved Versions drop-down list.
