It is recommended using DriveHQ FileManager 4.0 client software which works like Windows Explorer and you can easily drag and drop files / folders. For automatic backup, please use DriveHQ Online Backup 4.5. Both FileManager and Online Backup support SSL and Encrypted Folder. Encrypted Folder is more secure because files are encrypted locally with your own private key before they are uploaded. Thus files cannot be decrypted on server.
If you prefer FTP, we support FTP over SSL. For more info about DriveHQ FTP, please visit: http://www.drivehq.com/ftp/
