Hi, backing up a Cisco ASA gives the result that all pre-shared-keys are shown as "x"
Example: tunnel-group 188.8.131.52 ipsec-attributes
Result: if you would place this config back the tunnel would not function!!
If there could be a separate default backup-for ASA's with the command: more system:running-config
This would give as result a config which can be used for restore.
As workaround i scheduled this with log file and email result.
I sent you an email to try to get more information about your request.
