A rollback is a safety measure used when a new update causes unexpected crashes, system failures, or data issues.

The story behind the word. Originally used in the early 20th century to describe rolling back prices to a previous level. In the mid-20th century, database administrators adopted the term to describe undoing a transaction that failed to complete.
