Hi

I've got some time under my belt with WinSCP, so I'm not what i'd call a newbie.

I've had a script that backs up a remote SSH server to my local machine using SFTP. Its worked before, but it stopped working at some point. I'm not sure when exactly it stopped working. The script itself has not changed

I've been making regular upgrades to WinSCP. I was just using 4.0.7, but I've uninstalled and reinstalled back to 4.0.4 to see if it make any difference. It doesn't.

To troubleshoot, I've run my script line by line by hand in a "WinSCP.exe /console" window. There are no errors. Heres the script. Its really very simple

option batch continue
option confirm off
option synchdelete on
open HOST
synchronize local "D:\JDTEST\" "/D/WebDir"

Heres how it looks on in the console window

winscp> option batch continue
batch continue
winscp> option confirm off
confirm off
winscp> option synchdelete on
synchdelete on
winscp> open HOST
Searching for host...
Connecting to host...
Authenticating...
Using username "USER".
Authenticating with pre-entered password.
Authenticated.
Starting the session...
Reading remote directory...
Session started.
Active session: [1] HOST
winscp> synchronize local "D:\JDTEST\" "/D/WebDir"
Comparing 'D:\JDTEST' with '/D/WebDir'...
winscp>

For the purposes of this test, the local directory i'm using is completely empty.

when the synchronise command is entered, despite the message saying 'comparing....', the prompt returns immediately.
Nothing is copied from the remote to the local dir. Its as if WinSCP see's nothing in the remote directory - no files and no subdirectories, so it has nothing to do!
But I know there is data there because - from the same console window - i can manually traverse the remote directly structures using 'cd' and 'ls' commands, seeing everying
So, I know that the paths are correct and that there are files there. I also know that WinSCP is logged in and communicating.

Incidentally, i've also tried carrying out the same operation from the GUI and it works just fine!

It doesnt matter what i do, I'm unable to get this script, which once worked perfectly, to work anymore.
In fact i'm no longer able to get Synchronisation command to work in the console in any way at all.
Once again, *nothing* in the script itself has changed.

Can Anyone shed any light on this? I'm at a totall loss.

Here's the log file output from 4.0.7, and from 4.0.4

I can see several strange things in the log. I cannot tell which one or more of them is causing the trouble.

1) You have the Existing files only turned on. Hence WinSCP won't synchronize anything in local directory is empty.

2) The 4.0.7 log says 'Listing directory "D:\JDTEST\"', when it is listing the remote directory.

3) The 4.0.4 log says 'Listing directory "/D/InetPub".' in the same situation.

Thanks for the insight. I see what you're getting at.
please ignore the transposition of source and destination Dirs in the log file. I manually edited them. It was late - I was tired. Probably a manual mistake. I'll check this again and post back

Regarding 'Existing files only' synch option. I can see this in the GUI, in the synch dialogue. It is indeed checked.

Question: If i change this options in the GUI, and check 'use same option next time', are these options then used as my defaults in the console?

I guess I have a few questions:

1. I know that 'option synchdelete' is something i can set at concole level. Are the other synch GUI options adjustable from inside the console environment? such as 'Existing files only'. If not, how do i control them? Are they 'inherited' fom the GUI? Documentation and command help show only limited switches for the synchronise command (I did notice more flexibility with synch command coming in next version - very much looking forward to that)

2. Are synch options that are set from inside the GUI then stored in the registry/INI file?

4. Are synch options GUI settings 'global' or 'per session'

5. If I remove WinSCP and ensure all files and registry settings are cleared, would default install of 4.0.7 clear any difficulty, do you think? I didnt clear the registry when i uninstalled 4.0.7 / reinstalled 4.0.4. Are there any files or reg keys (beyond the obvious ones) that need to be manually removed to ensure that all trace of the app is gone?

phew!

Cheers Smile

OK

I think i answered my own questions.

'Existing files only' option seems to be global, not per session.
If i turn it off, and check the option to use 'same options next time' the synchronise console command now seems to work as expected.

So i guess at least some of the GUI settings are 'inherited' by the console.

So, many thanks for your assistance, I think I'm up and running again now.

Looking forward to the new version with the extended synch command functionality.

Many thanks again. Keep up the excellent work!!
