daily MSDOS batch script (.bat/.cmd) to do xcopy/e/c/h/D:d-m-y wrt 1st Sunday of the month

Hi,

I need a daily .bat/.cmd MSDOS script that runs at 1am that will :

a)If it's the first Sunday of the month, do :
xcopy/E/C/H/Y  n:\folder1  n:\backup\folder1\yyyymmdd  > n:\log\yyyymmdd_folder1.txt 2>> n:\log\yyyymmdd
xcopy/E/C/H/Y  n:\folder2  n:\backup\folder2\yyyymmdd  > n:\log\yyyymmdd_folder2.txt 2>> n:\log\yyyymmdd
     (ie take a full backup of folder1 & folder2;   yyyymmdd is the date the script run
      & n:  is a shared drive/folder)

b)If it's other days, do :
xcopy/E/C/H/Y/D:d-m-y  n:\folder1  n:\backup\folder1\yyyymmdd  > n:\log\yyyymmdd_folder1.txt 2>> n:\log\yyyymmdd
xcopy/E/C/H/Y/D:d-m-y  n:\folder2  n:\backup\folder1\yyyymmdd  > n:\log\yyyymmdd_folder2.txt 2>> n:\log\yyyymmdd
(this is a differential backup   to backup files that have been modified or  created since the
  last first Sunday of the month)

c)
in step (a) above, if it's the first Sunday of the month, it would delete away (using "deltree ?")
the folders that are 5 months old & subsequent differential backups' folders with respect to
that full backup's date.


Purpose of the >> and 2>>  is to create logs for review next morning if there's
errors with backup.

If you need to break this up into multiple scripts, it's fine with me.
Single script would be nice but not essential

OK. Give this a try. You'll need to remove the 6 ECHO in captials for the script to actually perform the operation.

The removing of the 5 month old backup folders will only remove differentials only in that month. Differentials that spill over to the next month will be removed next month's first Sunday.
