Abstract

In one example, a method includes receiving, at a client where a version of a file is locally stored, an inversion patch concerning the local file version, the inversion patch including original content of one or more byte ranges that embrace changes reflected in the locally stored version of the file version that were made subsequent to creation of a target version of the file with which the locally stored file version is associated, unlocking the local file version, and applying the inversion patch to the unlocked local file version to create a restored file version that matches the target version of the file. The restored file version is then saved.
