Handle network fail while copying files in C#

I am writing a C# app that copy files over a network, the problem is that the size of the files and folders to copy is more than 1 TB. My method is as follows

public static void SubmitDocsToRepository(string p_FilePaths) 
{
   IEnumerable<(string,string)> directoryLevels = GetAllFolders(p_FilePaths);
   IEnumerable<(string,string)> filesLevels = GetAllFiles(p_FilePaths);

   foreach (var tuple in directoryLevels) 
       Folder copy logic
   foreach (var tuple in filesLevels) 
       File copy logic                     
}

Which would work fine, but assuming something would happen to the network or remote server or the electric power gets lost for whatever reason what should I add to this code to allow me to continue where I left off, especially how could I retrace my steps to where I was.

It could be something like this:

public static void SubmitDocsToRepository(string p_FilePaths)
{
    IEnumerable<(string, string)> directoryLevels = GetAllFolders(p_FilePaths);
    IEnumerable<(string, string)> filesLevels = GetAllFiles(p_FilePaths);

    foreach (var tuple in directoryLevels)
        while (!CopyDirectory(tuple)) ;

    foreach (var tuple in filesLevels)
        while (!CopyFile(tuple)) ;
}

static bool CopyDirectory((string, string)tuple)
{
    try
    {
        // Copy logic
    } 
    catch 
    { 
        // Some logging here
        return false;
    }

    return true;
}

static bool CopyFile((string, string) tuple)
{
    try
    {
        // Copy logic
    }
    catch
    {
        // Some logging here
        return false;
    }

    return true;
}
