This feature is available only if the ZipArchive PHP library is installed in your server, which is a requested WordPress library.
If you upgrade to a new version the plugin will make an automatic backup of the current version (for example v 1.0.0.), creating a new zip dynamic-content-for-elementor_1.0.0.zip in the /wp-content/backup folder.
If you don't want these features you can disable it from the License Tab of Plugin Configuration.
After any plugin update you will find a new setting on the License Tab of the plugin Configuration.
This lets you perform an easy Rollback to your previous version simply by selecting the available versions and clicking on Rollback NOW.
The Rollback does not make any modification to your DB.
You can always return to your previous version or update to the latest if you do not like the current one.
Consider switching to the old version only if the update generates some irreparable errors.
