Rollback recovery is a fault tolerance mechanism in distributed systems that involves reverting a system to a previously saved state upon encountering a failure, thereby minimizing data loss and ensuring system consistency. This approach typically requires maintaining checkpoints or logs to restore the system to a known good state before the error occurred.

Distributed systems consist of multiple interconnected components that communicate and coordinate their actions by passing messages to achieve a common goal. They offer scalability, fault tolerance, and resource sharing, but also introduce challenges such as network latency, data consistency, and system complexity.

Data loss refers to the unintended destruction, deletion, or corruption of data, which can result from hardware failures, software bugs, human error, or malicious attacks. It can have severe consequences for individuals and organizations, including financial loss, reputational damage, and operational disruptions.

Checkpoints are control mechanisms in cellular processes, particularly within the cell cycle, that ensure each phase is accurately completed before progressing to the next stage. They play a crucial role in maintaining genetic stability by preventing cells with damaged DNA from dividing, thereby averting potential oncogenic transformations.
