A process exists where software or an operating system is retrieved from a remote server (the cloud) and then installed on a device using the already-present, locally stored files as a foundation. This approach differs from a clean install, which wipes the existing system. For example, when a computer experiences a software issue but the core operating system files are intact, a user might opt to download the necessary repair or update files from a cloud service. Once the files are received, the installation procedure utilizes the existing system configuration and files to apply the updates or repairs, rather than replacing the entire operating system.
This method provides several advantages. It often results in faster installation times, as only the necessary files are downloaded and applied. It can also preserve user settings, applications, and data, reducing the need for extensive reconfiguration after the installation. Historically, recovery methods relied heavily on physical media or complex imaging processes. The advent of high-bandwidth internet access and cloud storage has enabled this more streamlined, efficient approach, reducing reliance on physical media and simplifying the recovery or upgrade process for end-users.
