如何使用批处理文件重命名现有文件以进行备份？

pkzip25 -add=all -dir=current -silent -locale -exclude=DistData.zip -exclude=extract.bat -exclude=run.bat -exclude=pkzip25.exe -exclude=extracted.txt -exclude=zipped.txt -exclude=.\STORE DistData.zip *.*
pkzip25 -view -directories DistData.zip >zipped.txt

copy DistData.zip ..\BKX\DistData_1.zip
cd ..\BKX
rename DistData_1.zip DistData_2.zip 
rename DistData_2.zip DistData_3.zip
rename DistData_3.zip DistData_4.zip
rename DistData_4.zip DistData_5.zip
pkzip25 -add=all -dir=current -silent -locale -
