The line dir .\%YYYY%\%M%%MM%\%D%%DD%\Backup-serversave-%YYYY%-%M%%MM%-%D%%DD%--*.zip will look in the current directory for a folder named "2014\06\23" and a file "Backup-serversave-2014-06-23--*.zip".
In a batch file if you need to look in a specific directory you need to specify the full path somewhere, not use just a relative path. You can do this by changing to the base directory using a "CD" command or add the base directory to your path specification. Alternatively, specify a base directory and use "dir /s" to search all sub-directories. Using the sub-directory option you can remove all the date determination code.
See this post for some code samples.
To schedule programs you should use "Task Scheduler".
