How to track history of serial struct data?

[Chris75forumname]

As stated here, "Changes to struct data should be tracked in the revisions history of a page." When I checked I noticed, that changes to serial struct data do not invoke any revision records of that page. In the plugin manual it is stated that rev (revision id of the page) is logged in the database. But, how is that helping with recovery of historical struct data?
If I go to an ancient historical revision of my page (hosting serial struct data), the table is filled with just the recent struct content, not any historical data.

serial data does not track any history

Okay, thank you very much! That was the answer I was looking for. BTW, THANK YOU SO MUCH FOR ALL YOUR MAGNIFICENT WORK AND CARE!

1. So am I right, this is the advantage of the data plugin over the struct plugin, that history of "serial" data can be recovered and diffs can be viewed?
2. Could I just backup /data/meta/struct.sqlite3 together with a copy of the associated pages at the same timepoint to be able to roll back the history of the data? (assuming that schemas are stored inside this database together with all entries)

1. there is no such thing as serial data in the data plugin
