Where is a backup copy best stored for quick recovery?

Storing a backup copy onsite for quick access is effective for ensuring that recovery operations can be performed rapidly in the event of data loss or a system failure. Onsite storage allows for immediate retrieval of backup data without the delays associated with retrieving data from offsite storage or cloud services. This method is particularly beneficial in scenarios requiring fast turnaround times, such as during business disruptions or when critical systems are down.

While offsite warehouses can provide additional protection against local disasters and cloud storage offers flexibility and scalability, they often involve longer recovery times due to the need for data retrieval through physical transport or internet bandwidth limitations. Similarly, while an external hard drive offers a form of onsite storage, it may not be as integrated into existing systems for quick data recovery when compared to purpose-built solutions. Therefore, onsite storage strikes a balance between quick access and recovery time, making it the most practical option among the choices provided.
