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. Visual FoxPro

LOCAL lnSuccess
LOCAL loSftp
LOCAL lcRemoteDir
LOCAL lcLocalDir
LOCAL lnMode
LOCAL lnRecursive

lnSuccess = 0

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

loSftp = CreateObject('Chilkat.SFtp')

lnSuccess = loSftp.Connect("my-ssh-server.com",22)
IF (lnSuccess = 1) THEN
    lnSuccess = loSftp.AuthenticatePw("mySshLogin","mySshPassword")
ENDIF

IF (lnSuccess = 1) THEN
    lnSuccess = loSftp.InitializeSftp()
ENDIF

IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* 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.

lcRemoteDir = "syncUploadTest"
lcLocalDir = "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.
lnMode = 5
* This example turns on recursion to synchronize the entire tree. 
* Recursion can be turned off to synchronize the files of a single directory.
