SFTP Synchronize Directory Tree - Download

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

' Synchronize the remote directory tree rooted at "syncDownloadTest/xml"
' with the local directory tree rooted at "qa_output"
' 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 = "syncDownloadTest/xml"
localDir = "qa_output"

' Possible modes that can be passed to the SyncTreeDownload method are:
' mode=0: Download all files
' mode=1: Download all files that do not exist on the local filesystem.
' mode=2: Download newer or non-existant files.
' mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
' mode=5: Download only missing files or files with size differences.
' mode=6: Same as mode 5, but also download newer files.
' mode=99: Do not download files, but instead delete remote files that do not exist locally.

' This example will use mode 6 to download missing, newer, or files with size differences.
mode = 6
' This example will turn on recursion to synchronize the entire tree. 
' Recursion can be turned off to synchronize the files of a single directory.
