• فرض بر این است که مخزن کد SVN ایی را بر روی سرور راه اندازی کرده‌اید. همچنین پوشه‌ای را که می‌خواهید ریشه سایت باشد، مثلا در مسیر دلخواه C:\path\www قرار دارد.

• برای شروع کار، check out باید صورت گیرد. یا می‌توان از TortoiseSVN استفاده کرد یا چون مخزن کد در همان سرور است، دستور زیر نیز کار می‌کند:

svn checkout file:///c:/svn/MyRepository/trunk C:\path\www

• سپس یک فایل bat باید درست کنید با محتوای زیر:

svn update file:///c:/svn/MyRepository/trunk C:\path\www

• اگر می‌خواهید این پوشه‌های مخفی وجود نداشته باشند از دستور svn export استفاده کنید. فقط دقت کنید که در این حالت اگر فایلی از مخزن کد حذف شده باشد، باز هم در ریشه سایت وجود خواهد داشت. راه حلی هم که توصیه شده، این است که در همان bat فایلی که درست می‌کنید ابتدا دستور حذف محتویات پوشه ریشه را صادر کنید و بعد svn export . البته بدیهی است این روش نسبت به svn update کندتر است و svn update به شدت بهینه و سریع می‌باشد.

• یا راه دیگر بجای حذف کردن پوشه موجود و بعد export به آن، استفاده از برنامه‌هایی مانند Robocopy است که می‌توانند عملیات همگام سازی را هم انجام دهند. در این حالت محتوای فایل bat شما شبیه به دستورات زیر خواهد شد:

svn checkout file:///c:/svn/MyRepository/trunk C:\temp\Site1 >> output.log
robocopy C:\temp\Site1 C:\path\www *.* /S /XF *.cs *.tmp *.sln *.csproj *.webinfo /XD .svn _svn /PURGE >> output.log
