Install of snapshots has admin menu at the "Network Admin" level of the multisite. I can setup a snap shot for main root domain.tld and any of its multisites ie. abc.domain.tld.
Using Multi Domain I added domain2.tld which does NOT provide a root domain of domain2.tld only adds the domain2.tld to the drop down list to create multisites like xyz.domain2.tld.
Now where do I find snapshots admin to create backups of the added subdomain.domain2.tld multisites ? No drop down option is provided on the previously mentioned snapshots admin for adding backups for sites created using the 2nd domain.
