In this specific example yes, but if you see in my original post the backup was taken after an upgrade and it still said it required the previous version to be installed. If you have to keep every single version installed for backups to work, thats not ideal?
@elheladero
In this specific example I was restoring to the same host just to reproduce the error. What happens if you need to restore a backup from before your last update? does performing a site update render all historical backups obsolete?
My workaround is to manually extract the site backup and rsync the conf.d/wato files to restore the config, I have not run into any issues so far.
