Final answer:
A full backup is a complete copy of all data and files on a computer or system, while an image backup captures an exact snapshot of the entire system. Full backups include all files and allow for selective restoration, while image backups restore the entire system or partition. Full backups are useful for routine data protection and file restoration, while image backups are most useful for system recovery.
Step-by-step explanation:
a) Definition of a full backup:
A full backup is a type of backup that includes all the data and files on a computer or a system. It creates a complete copy of the entire system or selected files, allowing for easy restoration in case of data loss or system failure.
b) Definition of an image backup:
An image backup, also known as a system backup, is a type of backup that captures an exact snapshot of an entire computer system or a designated partition. It creates a file that contains all the data, settings, and configurations necessary to restore the system to its original state.
c) Differences between a full backup and an image backup:
- A full backup includes all files and data, whereas an image backup captures a complete snapshot of the entire system.
- A full backup usually takes longer to perform and requires more storage space compared to an image backup.
- A full backup allows for selective restoration of individual files, while an image backup restores the entire system or partition.
d) When to use each type of backup:
- A full backup is useful for routine data protection and for restoring individual files or folders that have been accidentally deleted or corrupted.
- An image backup is most useful for system recovery, such as after a hardware failure, system crash, or major software issues.
