the.com/rollback

means To revert a system, decision, or policy back to an earlier state, undoing whatever changes came after it.

from A straightforward compound of 'roll' plus 'back' — the image is of winding something backward, like film on a reel or a car's odometer. It entered technical English through software and database systems in the mid-to-late 20th century, where a 'rollback' means restoring a database to a previous, stable state after an error. From there it rolled (so to speak) into economics and politics, describing the reversal of price increases, regulations, or policies — always with that same mechanical undertone of cranking the machine back to where it used to sit.
