While ingesting Profile data, in Data prep (or if possible directly from the source) you can add an attribute that will be updated with the current date, and eventually, in Segment Builder you can use that attribute to filter the data and export.
Note: The above will also include any of the new profiles (which I believe would still be good).
Other than this, you can schedule a query to bring the relevant data from the Profile snapshot table to a new dataset and export the dataset to any cloud storage.
