Backup Exec - Server in another domain

Hi Experts,

I use BACKUP EXEC 2014.
Now I have another network with another domain connected to my firewall.
I want to use my backup server to backup the servers from the other domain.
is it possible ?

Yes - you just need to install the remote agent on the other server. They need to be on the same IP range and subnet though. Establish trust between the servers and ideally use the same credentials.

Thanks for the nice links.
The remote server is on a complete different subnet.
You may still be able to do it:

Allow use of any available network interface, subnet, or protocol for Backup Exec agents not bound to the above network interface, subnet, or protocol

Select this option to let Backup Exec use any available network if the remote system that you selected for backup or restore is not part of the specified backup network.

If you do not select this option and the remote system is not part of the specified backup network, the job fails. Backup Exec cannot access the data from the remote system.

Also another post here seems to suggest it is fine (although maybe sometimes a little funny):

ok I see and the network is ok and I use all networks.
But what do you think, do I need a domain trust ?
Benjamin Van DitmarsSr Network EngineerCommented:
install on the remote computer the agent for backup exec. and specify the ip address of youre backup server. you dont need an domain trust. add the machine and specify the credentials.
I would think that yes you need Trust established. That way you should be able to use the Domain account you use for Backup Exec on server 1 Domain 1 into the Domain Admins Group on the other Server 2 Domain2.

I can ping the backup server but cannot create the agent to connect.
All services are allowed.

I think without a trust it is not working.
Eprs_AdminSystem ArchitectAuthor Commented:
I can reach the vcenter of the other domain, but the backup is not possible.
Through the firewall all ports allowed.

But a backup of one VM fails always.

When I check the credentials I cannot connect to the VM with windows credentials but I entered the correct once for this machine. maybe its not possible without domain trust.

right ?
I believe you need trust yes
