We are using BoKS security suite which uses its own sshd, and also seems to require additional login credentials.
As a result, when BoKs is turned on, vertica backups using vbr.py fail with ssh errors.
If we turn it off, backups work, but that is not a long term option.
Release : 20.2
Component : PM Data Storage
BoKS is an access management tool that includes it’s own level of authentication.
This extra step is what is causing the SSH calls for the backups to fail.
You will need to edit the permissions within the security suite you are using to allow the vertica user to run SSH between the source and the target for the backups, even if it is the local host.
Every environment will be configured differently, but one site got this working by setting these permissions on their vertica user (dradmin)
dradmin - Logon, remote execution, fwd
Root - logon, remote execution, fwd and “authentication”
