CompTIA A+ (220-902) — Question 7

A technician needs to perform a backup while a system is running. Which of the following services allows this task to be accomplished?

Answer options

• A. Robocopy
• B. Shadow copy
• C. Xcopy
• D. System restore

Correct answer: B

Explanation

The correct answer is B, Shadow copy, as it allows for the creation of backups of files even while they are in use. Options A (Robocopy) and C (Xcopy) are primarily used for file copying and do not support live backups, while D (System restore) is designed for restoring system states rather than performing backups.
