[otrs] Problem with Backup under XP

Hi , I try to backup the OTRS database with the script backup.pl But I get the following error: C:\Program Files\OTRS\StrawberryPerl\perl\bin>perl "c:\Program Files\OTRS\OTRS\scripts\backup.pl" -d c:\backup_OTRS 'which' is not recognized as an internal or external command, operable program or batch file. ERROR: Can't locate cp! - What do I wrong here? - What is the best way to backup the OTRS database?
