To support multiple context, NCM solution is to configure multiple config type.
The Admin guide listed a list of things that need to be customized.
Do you have a sample device template for Cisco ASA to backup ASA with admin, customer1 and customer2 contexts?
The Admin guide also stated the customized context cannot be scheduled for backup, is that real?
What's the point of setting all these customizations for each context but not be able to back them up?
