A data backup plan is crucial because it ensures that access to important information is preserved in the event of data loss or corruption. Various factors, such as hardware failure, accidental deletion, malware attacks, or natural disasters, can lead to the loss of critical data. By having a robust backup strategy in place, organizations can recover data quickly and minimize disruption. This capability is essential for maintaining business continuity and safeguarding valuable information, ultimately protecting an organization's operations and reducing potential losses.

The other choices do not accurately represent the primary purpose of a data backup plan. For instance, while data can be backed up to mitigate loss, it does not guarantee that data will never be deleted, nor is the preservation of data the sole purpose of storage management. Making more storage space and enhancing system performance are not direct objectives of a backup plan. Instead, those are separate considerations that can be addressed through different strategies in data management.
