The backup type that must be implemented to ensure a server OS and data can be recovered in case all the server's hard disk drives fail simultaneously is a "Bare Metal" backup.
A "Full Backup" is a backup of all the data on the server, including the operating system, applications, and user data. It is a complete backup of all data and is typically performed on a regular basis, such as daily, weekly, or monthly. While a full backup can be used to restore data in case of data loss, it does not necessarily include a complete system recovery.
A "Differential Backup" is a backup of all data that has changed since the last full backup. It only includes data that has been added or changed since the last full backup. This backup type requires both the last full backup and the last differential backup to be restored in case of data loss.
An "Incremental Backup" is a backup of all data that has changed since the last backup, which could be either a full or incremental backup. It only includes data that has been added or changed since the last backup. To restore data, all incremental backups since the last full backup must be restored in order.
A "Bare Metal" backup, also known as a system image backup, is a complete backup of the entire server, including the operating system, applications, system settings, and user data. It creates a snapshot of the entire system as it is at the time of the backup, allowing for a complete system recovery in case of a catastrophic failure, such as a hard drive failure or corruption of the operating system.
Therefore, the backup type that must be implemented to ensure a server OS and data can be recovered in case all the server's hard disk drives fail simultaneously is a "Bare Metal" backup.
