SFTP Upload - Synchronize Directory Tree

Demonstrates how to upload files to synchronize a local directory tree with a remote directory tree. The SyncTreeUpload method recursively descends a local directory tree and uploads files based on existence, last-mod date/time and/or size differences.

' Synchronize (by uploading) the local directory tree rooted at "qa_data/sftpUploadTree"
' with the remote directory tree rooted at "syncUploadTest"
' Both directories are relative paths.  The remote directory
' is relative to the HOME directory of the SSH user account.
' The local directory is relative to the current working directory of the process.
' It is also possible to use absolute paths.

remoteDir = "syncUploadTest"
localDir = "qa_data/sftpUploadTree"

' Possible modes that can be passed to the SyncTreeUpload method are:
' mode=0: Upload all files
' mode=1: Upload all files that do not exist on the server.
' mode=2: Upload newer or non-existant files.
' mode=3: Upload only newer files. If a file does not already exist on the server, it is not uploaded.
' mode=4: transfer missing files or files with size differences.
' mode=5: same as mode 4, but also newer files.

' This example will use mode 5 to upload missing, newer, or files with size differences.
mode = 5
' This example turns on recursion to synchronize the entire tree. 
' Recursion can be turned off to synchronize the files of a single directory.
