i think there is folder called public_html ? Normall www will be mirroring only ... not too sure ... but if u still can access your website ... then just simply create new folder called www. I think it should auto mirroring,
Beware, as R1 soft will overwrite each older backup, after a new backup is created.
It cannot be worse than what's happening now ... as he accidentally delete www file. Maybe he will need to backup database as I'm not sure if R1 Soft will restore the database ... other than that cannot be worse as he has no other option except re uploading the file again.
The databases are not affected by R1Soft, but they are also not affected by deleting the WWW folder.
