New backup process?

When I went to back up on the cloud version (25.9.8.2752) I noticed it has changed; there is no longer the options to include attachments etc. I backed up my files and I note the backup is much smaller than before; e.g. my July backup is 229.3Mb; the same company backed up in August is only 9Mb; I cannot imagine the data in this backup contains all of my data. Can anyone explain? Should I be using the export option instead?

OK I have found that to backup now you have to log in to your domain to do so. It says it is “refreshed once a day”. When is the refresh so I can ensure I get the latest entries?
