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. Objective-C

#import <CkoSFtp.h>
#import <NSString.h>

BOOL success = NO;

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

CkoSFtp *sftp = [[CkoSFtp alloc] init];

success = [sftp Connect: @"my-ssh-server.com" port: [NSNumber numberWithInt: 22]];
if (success == YES) {
    success = [sftp AuthenticatePw: @"mySshLogin" password: @"mySshPassword"];
}

if (success == YES) {
    success = [sftp InitializeSftp];
}

if (success != YES) {
    NSLog(@"%@",sftp.LastErrorText);
    return;
}

// 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.

NSString *remoteDir = @"syncUploadTest";
NSString *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.
int 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.
BOOL recursive = YES;
success = [sftp SyncTreeUpload: localDir remoteBaseDir: remoteDir mode: [NSNumber numberWithInt: mode] bRecurse: recursive];
if (success != YES) {
    NSLog(@"%@",sftp.LastErrorText);
    return;
}

NSLog(@"%@",@"Success.");
