I have a Terastation Pro II (TS H2.0 TGL/R5 firmware 1.22), a Linkstation Pro duo (LS-W1.0TGL/R1-V3 formware 3.03) and a TeraHS (HS-D1.0TGL/R5 firmware 2.03)
For backup issues, Both Terastations does not appear under he "linktation list" in the "backup" menu of the web admin page. they do not appear under the "terastation list" for backup when i open the web admin age of each of them.
Than you for helping me.
I can give more info if needed, but i work with a Philips ADSL routeur, with a D-LInk splitting hub
