Managed WordPress Multisite Backup
It would be great to have an option to back up a multi-site wordpress network and then be able to restore only one subsite of that backup.
Example: I have a multisite network with 100 customer sites. I backup my network daily. If a client in my network asked me to restore a backup I would only restore that client's site and not the entire network.
I know that Cloudways works in partnership with BlogVault.
BlogVault already has a WordPress Multisite compatible backup system.
You could integrate this solution into the Cloudways administration panel.
