(Xojo Plugin) 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.

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

Dim sftp As New Chilkat.SFtp

Dim success As Boolean
success = sftp.Connect("my-ssh-server.com",22)
If (success = True) Then
    success = sftp.AuthenticatePw("mySshLogin","mySshPassword")
End If

If (success = True) Then
    success = sftp.InitializeSftp()
End If

If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return

// 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.

Dim remoteDir As String
remoteDir = "syncDownloadTest/xml"
Dim localDir As String
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.
Dim mode As Int32
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.
Dim recursive As Boolean
recursive = True
success = sftp.SyncTreeDownload(remoteDir,localDir,mode,recursive)
If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
End If

System.DebugLog("Success.")
