Full backups refer to a complete copy of all selected data at a specific point in time. Snapshots and images are both methods that capture the exact state of the system and its data, effectively representing a full backup.

Snapshots are a point-in-time representation of the data that allows for recovery to that exact state, while images typically refer to a complete disk image that includes the entire file system and operating system files. These methods ensure that everything is included in the backup, which aligns with the purpose of a full backup – capturing all data for recovery needs.

In contrast, disk backups and folder backups focus more on selecting specific types or locations of data rather than creating a complete representation. Cloud storage and tape storage refer to media or location rather than the specific type of backup performed. Incremental and differential backups describe methodologies that involve backing up only the changes since the last backup, which is fundamentally different from a full backup.
