Backup & Recovery Methods

A system admin performs a backup that copies every file on a workstation each night, even if no files were modified. Which backup type is being used?

Full backup

A workstation backup strategy uses a full backup on Sunday and small daily backups that capture only the files changed since the last backup. What type of backup is being performed?

Incremental backup

Which backup type copies all data changed since the last full backup?

Differential backup

A backup strategy uses a weekly full backup and daily incrementals, then creates a new full backup copy by combining existing backup data instead of pulling data from the workstation. What type of backup is generated?

Synthetic full backup

A technician is configuring a backup schedule. The goal is to ensure that daily backups include only files modified since the previous day and that the backup process marks those files as backed up. Which backup type should be used?

Incremental backup

In a differential backup strategy, restoring data from backup requires a working copy of the last full backup and the most recent copy of the differential backup. (T/F)

True

A workstation uses a full backup on Sunday at 11:00 PM and an incremental nightly backup schedule at 11:00 PM on weekdays. The system fails on Friday at 9:00 AM. How many backup sets must be restored to fully recover the system?

5

A technician restores a user’s documents directly back into the original Documents folder, replacing the corrupted files. What type of recovery is being performed?

In-place/overwrite recovery

A backup copy of data is being restored to a temporary folder on a secondary drive to compare versions of files before replacing anything. What recovery method is being used?

Alternative-location recovery

A scheduled restore test is performed each month to ensure that the backed-up data has not been altered or corrupted. The purpose of this activity is to verify the backup's:

Integrity

A company's backup policy states that restore tests must be performed once per week to verify that mission-critical data remains recoverable. This requirement defines the company's:

Backup testing frequency

The advantages of on-site backups over off-site backups include:

Faster data access and restore speeds

Greater control over backup media & backup process

Lower or no ongoing subscription fees

What are the advantages of off-site backups in comparison to on-site backups?

Improved physical and environmental security

Geographic redundancy

Scalability without additional on-premises hardware investment

A company utilizes a backup rotation scheme where backups performed daily during a week are used to create a weekly backup and backups created at the end of each week are used to create a monthly backup. What type of backup rotation scheme is being used?

Grandfather-Father-Son

Which of the answers listed below can be used to describe the 3-2-1 backup strategy?

Keep at least 1 backup copy offsite

Maintain 3 total copies of data (original + 2 backups)

Use at least 2 different storage media types
