In db parlance, schema means two different things really.
One is that layout of your data (how tables are related etc...)
The other is the namespace that a set of objects can live in. i.e.
There is a certain amount of overlap here as well.
dbname.schemaname.objectname.fieldname
In this instance, "backing up" a schema pretty much implies the
namespace version of schema.
OTOH, a phrase like "I think your schema has some design flaws pretty
obviously points to the first definition relating to the layout of
your data.
