Backup getting error 690: Host doesn't have any SAN or iSCSI ports defined

[matinlotfali]

Hey. I have a local & physical Windows Server 2019 which I want to backup using Google Backup and DR.

The backup appliance is up, the agent is installed on my host, partitions are discovered, backup template is set up. But when the backup job runs, I get the error 690:

Host doesn't have any SAN or iSCSI ports defined

I can't find anything specific on the tutorials about it. I don't believe that I have any iSCSI on my server and it is only for VMs, and not physical servers. Am I right? There is also nothing related to iSCSI in my server BIOS to enable or disable. When I remove the iSCSI item in the Host options, it returns in the options.

What should I do?

Hello @matinlotfali,

Welcome to Google Cloud Community!

Based on the error "Host doesn't have any SAN or iSCSI ports defined", it occurs if the backup/recovery appliance is not configured with the iSCSI connection to the target host.

You need to ensure the network ports are open for iSCSI and the target host has discovered the backup/recovery appliances.

For Firewall configurations:

---

The following ingress firewall rules are automatically added as they are requirements for Backup and DR.

Purpose	Source	Target	Port (TCP)
Support traffic (support to appliance)	Host running SSH client	Backup/recovery appliance	26
Management traffic (Console to appliance)	Management console	Backup/recovery appliance	443
iSCSI backup (host to appliance)	Host running Backup and DR agent	Backup/recovery appliance	3260
StreamSnap traffic (appliance to appliance)	Backup/recovery appliance	Backup/recovery appliance	5107

For any host that is running the Backup and DR agent, you need to manually add the following TCP port to allow connectivity with an ingress firewall rule.

Purpose	Source	Target	Port (TCP)
Agent traffic (appliance to host)	Backup/recovery appliance	Host running Backup and DR agent	5106

For hosts using NFS for backup traffic, or for ESX hosts running in VMware Engine that are using NFS for mounts, you need to manually add the following TCP and UDP ports to allow connectivity with an ingress firewall rule.

Purpose	Source	Target	Port (TCP/UDP)
NFS backup or mount	Host running Agent or ESXi host running mount	Backup/recovery appliance	111, 756, 2049, 4001, 4045
