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. PureBasic

    ; 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.

    remoteDir.s = "syncUploadTest"
    localDir.s = "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.
    mode.i = 5
    ; This example turns on recursion to synchronize the entire tree. 
    ; Recursion can be turned off to synchronize the files of a single directory.
