Just like a symbolic link, where we need to know what it points to. On Wed, Oct 21, 2009 at 10:03 AM, Keith Stattenfield <keith@stattenfield.org> wrote:

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.
