I'm looking for some recommendations of a USB storage device that would best be suited for Windows Essential Server 2012 R 2 Windows Server backups .
Hello Philip,
Any USB drive will do as long as you get a minimum of three to rotate. I also use a NAS and have that configured for iSCSI as an extra storage option.
why the minimum of three to rotate?
One is connected to the server, one you carry with you and one is on a remote location. See also https://en.wikipedia.org/wiki/Backup_rotation_scheme
