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. Chilkat2 Perl

use strict;
use warnings;
use Chilkat2;

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

my $sftp = Chilkat2::SFtp->new;

my $success = $sftp->Connect('my-ssh-server.com', 22);
if ($success) {
    $success = $sftp->AuthenticatePw('mySshLogin', 'mySshPassword');
}

if ($success) {
    $success = $sftp->InitializeSftp();
}

if (!$success) {
    print $sftp->LastErrorText, "\n";
    exit;
}

# 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.

my $remoteDir = 'syncUploadTest';
my $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.
my $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.
my $recursive = 1;
$success = $sftp->SyncTreeUpload($localDir, $remoteDir, $mode, $recursive);
if (!$success) {
    print $sftp->LastErrorText, "\n";
