Wordpress backup integration. Not a real backup

Wordpress backup integration. Not a real backup

Hello,

Our Wordpress backup should come out to a compressed size of around 1.6Gigabytes.

Once I managed to get the Wordpress Connection working and then configured a Skyvia backup process against this, the resutled data comes out to 3.2Megabytes.

So either I have seriously misunderstood what Skyvia backup is offering to backup, or something really isn't working. 

Does anyone have an idea of what might be happening?
