SFTP Upload - Synchronize Directory Tree

See more SFTP Examples

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. Xojo Plugin

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// 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.

Dim remoteDir As String
remoteDir = "syncUploadTest"
Dim localDir As String
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.
Dim mode As Int32
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.
Dim recursive As Boolean
recursive = True
success = sftp.SyncTreeUpload(localDir,remoteDir,mode,recursive)
If (success <> True) Then
