How to get a copy of backup config

Is there a way of getting a copy of the backup configuration of a cDOT node running 9.1 other than FTP or HTTP to an external source?

Before I de-commission the cluster, I would like to get a copy of the backup config, just in case I have to rebuild the cluster.  I am hoping to find out what the location in the systemshell is so I can hopefully SCP the file to another location.  I can't get a FW rule created for FTP or HTTP but I can get to the cluster via port 22 and was hoping to use SCP to transfer the file(s).

Any methods besides the FTP or HTTP path?

Thanks.
