SFTP Synchronize Directory Tree - Download

See more SFTP Examples

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. Classic ASP

'  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.

remoteDir = "syncDownloadTest/xml"
localDir = "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.
mode = 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.
