Explanation:
A full backup is a complete, comprehensive backup of all files on a disk or server. The full backup is current
only at the time it’s performed. Once a full backup is made, you have a complete archive of the system at that
point in time. A system shouldn’t be in use while it undergoes a full backup because some files may not get
backed up. Once the system goes back into operation, the backup is no longer current. A full backup can be a
time-consuming process on a large system.
An incremental backup is a partial backup that stores only the information that has been changed since the last
full or the last incremental backup. If a full backup were performed on a Sunday night, an incremental backup
done on Monday night would contain only the information that changed since Sunday night. Such a backup is
typically considerably smaller than a full backup. Each incremental backup must be retained until a full backup
can be performed. Incremental backups are usually the fastest backups to perform on most systems, and each
incremental backup tape is relatively small.
