title: Upload file fragment by FTP
body: <p>I need to develop a backup application for my company, saving files to an FTP server. From what I researched, I can use the TIdFTP component of the Indy library.</p>
  
  <p>I was analyzing here, and I noticed that some files, especially database files, are more than 10GB in size.</p>
  
  <p>My question is: Is there any way that if a connection problem occurs, the file copy restarts from where it left off?
   Without having to restart from scratch?</p>
  
  <p>I am using Delphi XE6.</p>
