Hi mazzasette,
Unfortalblely, power bi desktop doesn't include in the cache history data feature. These old version data will be updated/replaced if your source data changes.
Perhaps you try to use integrate R or Python scripts to backup operation to export these history data to local device and name with system DateTime.
