1. Compress the backup/export file(s) to a zip archive using WinZip or 7-zip,  
If the ZIP file(s) are larger than 150 MB, you can split them into smaller files so that you can simultaneously upload more than one file. If there are many physical files that are not related to this issue (typically media files), feel free to remove them from the backup.

2. Connect using a client like FileZilla to the nearest server and the credentials below. If you see connection errors, make sure you are connecting in passive mode over TLS.

Western Europe: EU-west.ftp.kentico.com
U.S. East Coast: US-east.ftp.kentico.com

The user name and password will be sent in an e-mail message or, you can request them at support@kentico.com.

3. Create new folder on the FTP server. Please use ticket number for the folder name (for security reasons, do not use company or project name). Make sure to enter the name when you create the folder, since for security reasons you are not allowed to modify folder names. If you make a mistake, just make a new folder and let us know.

4. Upload compressed file(s) into the recently created folder.

5. Let us know where the backup is located.
