Which of the following could be a disadvantage of a full backup strategy?

A full backup strategy involves copying all data in a system, which can lead to increased time for backup completion. This is because every file and piece of data, regardless of whether it has changed since the last backup, is included in the full backup process. As a result, the time taken to complete these backups can be longer compared to incremental or differential backup strategies where only changed data is backed up after the last backup.

In addition, the amount of data being backed up may require more storage space, which can also contribute to longer backup times. Because of these factors, businesses with large amounts of data may find full backups to be time-consuming, especially during windows when backups need to be completed quickly. The increased duration for backups can impact overall productivity and resource availability within an organization.

While the other options present potential issues with different backup strategies, they do not directly pertain to the core disadvantage of a full backup strategy. For instance, data corruption is not necessarily a direct disadvantage of full backups specifically; it can occur in any backup type depending on various factors such as hardware failure or human error. Similarly, the statement about lower data recovery options and high compatibility with cloud services does not reflect the inherent challenges associated with a full backup strategy itself.
