Hi there,

As your site sounds quite small there is another method may be quicker/simpler.
I’ve provided you directions for the approach you describe but this may be easier.

First, run a backup from the source site to a remote storage location like OneDrive.
Next, connect the destination site to the same remote storage and scan backups.

You can scan for backups using the ‘Rescan remote storage’ link in Existing backups.
Once the backup is displayed you can restore the backup directly from the interface.

If for some reason this approach isn’t possible you could use your email approach.
However, be warned this approach may fail due to size limits related to the email.

To try it select the email option in the icons in the storage options. Save changes.
Then run the backup and when the mail arrives download the files to your drive.

In the Backup/Restore tab, under Existing backups, select ‘Upload backup files’.
Upload all the backup files. When they’re all done you can click to restore them.

Best regards,

Nick
