This is the best description of a synthetic full backup method because it creates a full backup by combining previous incremental backups with the latest backup. An incremental backup copies only the files that have changed since the last backup, while a full backup copies all the files. A synthetic full backup reduces the storage space and network bandwidth required for backups, while also simplifying the restore process by using a single

Incremental backup is a type of backup that only backs up the files that have changed since the last backup, whether it was a full or an incremental backup. Incremental backup resets the archive bit each time it is run, which means it clears the flag that indicates whether or not the file has been backed up. Incremental backup can save time and space compared to full backup, but it requires more time and resources to restore data from multiple backups.References: (Objective 3.1)

A Full Backup involves copying all data from a system, regardless of whether the data has changed since the last backup. This process ensures that a complete, standalone copy of all data is available, facilitating straightforward restoration without the need for additional backup sets.

Other Backup Types:

A. Incremental Backup: This method backs up only the data that has changed since the last backup of any type (full or incremental). While it is storage-efficient and has a faster backup time, restoration requires all incremental backups since the last full backup, making the recovery process more time-consuming.

B. Differential Backup: This approach backs up all data that has changed since the last full backup. It simplifies the restoration process compared to incremental backups, as only the last full backup and the latest differential backup are needed. However, it consumes more storage space and takes longer to perform as time progresses.

C. Archive: Archiving involves moving data that is no longer actively used to a separate storage system for long-term retention. It is not a backup type but a data management process aimed at freeing up primary storage space.

D. Snapshot: A snapshot captures the state of a system at a specific point in time. While it provides a quick way to restore a system to a previous state, it is typically stored on the same system and is not a substitute for a full backup.

In summary, the Full Backup is the only method that captures all data irrespective of changes, ensuring a comprehensive and independent data copy.
