Why each option
The most effective method for a comprehensive backup system providing full restore capability for a web server is taking nightly image backups while the server remains online.
An image backup captures the entire operating system, applications, and data as a complete replica of the server, enabling a rapid and comprehensive bare-metal restore. Performing this nightly ensures minimal data loss and continuous protection, even when the server is operational.
Incremental backups only store changes since the last backup, making full restoration complex and time-consuming as it requires the initial full backup plus all subsequent incremental backups. Taking the server offline for backups causes service interruption and is generally avoided.
