An administrator is creating a comprehensive backup system to backup a single web server. Which of the following is the BEST way to provide full restore?

An image backup captures a complete sector-by-sector copy of the server, allowing a bare-metal restore to exactly the state at backup time. Taking it nightly minimizes data loss to at most one day, and performing it while the server is online (using VSS or similar snapshot technology) avoids service interruption while still ensuring data consistency.

An incremental backup only captures data changed since the last backup, so a full restore requires the last full backup plus every incremental in sequence, making recovery slower and more complex.

Monthly snapshots leave up to 30 days of potential data loss, which is far too infrequent for a comprehensive backup strategy on a production web server.

A differential backup captures all changes since the last full backup, but the question does not describe a full backup also being taken, and differential alone cannot provide a complete bare-metal restore.
