Hi Perry,

Thanks for that - basically, we have a DR site and our Server Admins have configured WANSync to do regular, block-level copies of all the MDF and LDF files from the live server to a backup server. I was just wondering if these would be sufficient to restore a system database, or whether we would need BAK files instead (we are already creating them, they're just not as easily to hand as the MDF and LDF copies!)

Thanks
