I am using Online Backup with a Multi-site installation now and it seems to be working very well. I just did my first trial restore and it looks like everything came back just fine.
What I would like to see in a multi-site support is an option to hide the backup options from sub-site owners. In other words, as a multi-site administrator, I would like to have backups performed and managed without sub-site owners needing to worry about the details. Also it is important to protect one site owner from backing up another site owner's content/database.
