We are using Netvault Backup Software ( 18.104.22.168) with Dell DR4300e appliance and Dell Standalone tape drive(Single drive LTO6). We have 4 Red hat Linux Netvault clients outside firewall and Netvault server is inside firewall . We have configured all necessary ports on our firewall to establish the connection between Netvault Server and 4*Netvault Clients.
Firewall test and Check access test is passed for all 4 Client machines, but whenever we try to start a backup, we always get a message: Running:Waiting for media and backup never happens.
Any help would be appreciated.
