Hello,

We are starting to patch our Fortinet devices. Several of them are configured in HA (FortiGate, FortiAuthenticator, FortiWeb, FortiADC, and FortiMail).

In a critical scenario, we may need to restore the OS via TFTP on each node.

In this case, should we take a separate backup from each HA member, or would restoring the HA backup on both devices be sufficient to fully recover the cluster configuration?

Hi Sino

Here is for FGT:

I think it should be the same for FWB, FML and FADC only if they are in active-passive HA.

For other HA modes (like config-only) I don't know but I'd take backup from both nodes, just in case.
