Combining Multiple XCOPY Commands

As shown in the following batch file, I use multiple xcopy commands to =
back up my work files. From an icon "Backup" I run the batch file. =
Unfortunately for each xcopy command a message comes up like "Overwrite =
F:\All Data Files\Address Book\Anders\wab <yes/No/All>?" and I will have =
to type an a before that command line can be completed. Before my whole =
backup is completed, I have to type in an a five times. Is that a switch =
or a command I can add in order to avoid typing in the a manually?=20

Xcopy C:\"All Data Files" F:\"All Data Files" /d:09-24-2007/c/e/h/k/r/s
Xcopy C:\"Do***ents and Settings"\"Anders" F:\"Do***ents and =
Settings"\"Anders" /d:09-24-2007/c/e/h/k/r/s
Xcopy C:\"ControlResearch" F:\"ControlResearch" =
/d:09-24-2007/c/e/h/k/r/s
Xcopy C:\"Faxitron" F:\"Faxitron" /d:09-24-2007/c/e/h/k/r/s
Xcopy C:\"Pictures" F:\"Pictures" /d:09-24-2007/c/e/h/k/r/s

rem This file Backup.bat is on C:\All Data Files\Batch Files
rem It is executed by double clicking an icon desktop
rem Valid as of Sep 24, 2007

Any help will be appreciated,
