(Lianja) 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.

loSftp = createobject("CkSFtp")

llSuccess = loSftp.Connect("my-ssh-server.com",22)
if (llSuccess = .T.) then
    llSuccess = loSftp.AuthenticatePw("mySshLogin","mySshPassword")
endif

if (llSuccess = .T.) then

// 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.

lcRemoteDir = "syncDownloadTest/xml"
lcLocalDir = "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.
lnMode = 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.
llRecursive = .T.
