Within environments where a dedicated backup network is specifically selected, Enterprise Vault backups may not protect partition and index resource locations configured within Enterprise Vault to use a DNS alias.
If the "Allow use of any available network interface, subnet, or protocol for Backup Exec agents not bound to the above network interface, subnet, or protocol” option is selected in "Network and Security", the job will complete but will utilize the production network.
The Media Server was unable to connect to remote machine vaultserver.domain.local using subnet 10.0.0.0/23 on network interface Network Team.
This issue applies to environments which possess dedicated backup networks and interfaces. Upon deeper investigation, individual machines belong to the same network and subnet.
Backup Exec determines the subnet for an interface based on entries in the Advertisement Cache, which stores details on Remote Agents advertising back to the media server. The Backup Exec Remote Agent does not publish information for Enterprise Vault Index and Partition resources configured with DNS alias and assumes these resources possess a 255.255.255.255 subnet mask.
1. From Backup Exec default or individual job settings, select "Network and Security".
2. Check the "Allow use of any available network interface, subnet, or protocol for backup Exec agents not bound to the above network interface, subnet, or protocol”
This may cause traffic to run over the production network, but will allow for a successful backup of Enterprise Vault Partition and Index resources.
