Full Export but huge data size

Hi,

I'm trying to have a full export to ThingworxStorage as backup for version upgrade.Once I click to start exporting, it gets started but no ending and no export database completion logs.

So I tried again and waited for long and finally got export database completed message in logs after an hour almost but with a size of GB's.And I'm not sure it's impacting my application too in terms of speed.

Please provide resolution for normal export completion time and size.

TIA!
