Here’s the email I sent to BackupBuddy support regarding an issue I ran into after updating to version 184.108.40.206.
I updated BackupBuddy from 6.5.0.x to 220.127.116.11 today on a multisite installation using subdomains. In addition to scheduled backups running for the installation as a whole as they did prior to the update, they now also run for every subdomain. The installation backups appear to be completing successfully. I get the error in the attached image for the subdomains.
