Backup (pull) running-config from CISCO ASA using SCP
Note to my self, mostly, took some time to find this, I was able to scp to copy file from/to the flash disk (disk0) on the device, but was not able to pull the configuration, unlike the CISCO switch I have. so it seems you need to prefix the path with
system:// to pull the running config, e.g
scp email@example.com:system://running-config .
scp firstname.lastname@example.org:system://running-config newfilename.cfg
