Much smaller 'snapshots' after changing to 'MariaDB'

Is that true, that size of ‘snapshots’ is much smaller, when switched to ‘MariaDB’?
Or it is something wrong…?
See below the 2 1st files, ‘snapshots’ made after switching to ‘MariaDB’.
Before that the size was ~200MB.

with mariadb, the database most probably moved out of /config folder of hassio, so you are not backing up the database.

Or maybe more likely, the dB will build up to the retained days you set and will expand say over a week…

yes… forgot mariaDB is also official hassio add-on :upside_down_face:

That sounds very good…
