I need to find an external hard drive that will backup my SBS 2008 server. I know there is a list of hard drives recommended to backup SBS but it is outdated and a lot of the hard drives are no longer sold by the makers. I also understand on this list there are certain hard drives that have been tested for both backup and recovery. I would like recommendations on more recent external hard drives that have been tested successfully for backup and restore. At least 1.5 TB hard drives should be sufficient.
