Fallback
Plan B
Fallback can imply a secondary plan, often less ideal but reliable.

If our fundraiser fails, selling T-shirts will be our fallback.
Not Primary
A fallback isn't your first choice; it's what you resort to when needed.

I applied for several jobs, using retail work as a fallback.
Security Sense
Fallback evokes a sense of security, as an alternative is ready.

In case of rain, the fallback will be to have the event indoors.
