This wont tell you if whether or not it's an alias file if that's what
you're asking. It will only tell you it hasn't found the target.
Eg, a regular file, say xx.alias, will be indistinguishable from a
genuine alias who's target is on an unmounted filesystem, has been
deleted, or is otherwise unavailable for whatever reason.

I see that FSResolveAliasFile() fails when its cannot find target of
the alias with the error fnfErr. In case of a file with a .alias
extension which is not an alias file, could I use this error return
value ?

My aim here is to know when I backup what the alias file points to and
then backup the alias file along with the name of the file it points
to.
Just like a symbolic link, where we need to know what it points to.

This looks good.
However, with a backup application, I would typically be using
FSIsAliasFile() to identify an alias and then use
FSResolveAliasFile()
to resolve it. However,here the FSResolveAlias() file would fail
causing issues. Need to deal separately with these cases
In general, you'd backup the contents of the alias file, not what it
points
to, because there's no guarantee that you can resolve the alias --
it might
be to an item on a file server that isn't accessible, or to an
un-mounted
local disk, or to an item that you'd need a password from the user to
resolve, or even be an alias to an item which has been deleted.
