Use ROBOCOPY not XCOPY. It will do what you want very easily. Robocopy is installed on Windows 7 and is a free download for other versions.

ROBOCOPY /S /MAXAGE:90 P:\path\to\source Q:\path\to\dest

There are many other options, for minimum age, min and max size, attrributes, filtering by file and directory names, and so forth.

Also you can use the /L option to just list what it would have done, to check you have the other options right.
