Snapshot unable to backup multisite Sites with edited names

Because we already have a domain at "" we created a subdomain at and used that for our WP MultiSite installation.

As a result, our default Site is
And any new site is by default

However, we edit those site names in WP to be (dropping "gsadmin"), and then create a redirect on the subdomain in our DNS provider, so those edited subdomains work properly. The results have worked fine so far.

But Snapshot Pro does not recognize the edited name "" as something it can back up. Nor does it recognize the original name,

Will using the Domain Mapping plugin fix this, or is there something else we've missed?
