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. Xbase++

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

oSftp := CreateObject("Chilkat.SFtp")

nSuccess := oSftp:Connect("my-ssh-server.com", 22)
IF (nSuccess == 1)
    nSuccess := oSftp:AuthenticatePw("mySshLogin", "mySshPassword")
ENDIF

IF (nSuccess == 1)

//  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.

cRemoteDir := "syncUploadTest"
cLocalDir := "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.
nMode := 5
//  This example turns on recursion to synchronize the entire tree. 
//  Recursion can be turned off to synchronize the files of a single directory.
