Backup & Recovery Methods

What backup type copies every file on a workstation each night, even if no files were modified

Full backup

What type of backup performs a full backup once a week, and small daily backups that only capture changed files since last backup

Incremental backup

What type of backup copies all data changed since the last full backup

Differential backup

What backup type uses a weekly full backup and daily incremental backups, then creates a new full backup copy by combining existing backup data instead of pulling data from the workstation

Synthetic full backup

What type of backup should be used to do daily backups that only include files modified since the previous day and the backup process marks those files as backed up

Incremental backup

What backup requires a working copy of the last full backup and the most recent copy of this backup

Differential backup

What type of recovery method restores a user’s documents directly back into the original Documents folder, replacing the corrupted files

In-place/overwrite recovery

What recovery method restores a backup copy to a temporary folder on a secondary drive to compare versions of files before replacing anything

Alternative-location recovery

What is the purpouse of a scheduled restore test each month to ensure that the backed-up data has not been altered or corrupted

Verify the backup’s integrity

What defines how often restore tests must be performed

Backup testing frequency policy

What are the advantages of on-site backups

• 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

• Improved physical and environmental security

• Geographic redundancy

• Scalability without additional on-premisis hardware investments

What type of backup rotation scheme is where backups performed daily are used to create weekly backups, and backups created weekly are used to create monthly backups
