(ExtException) **Copying files to remote side failed.**

Hi fellows.

In a batch file I use the following:

start /min winscp.exe /console /command "option batch on" "open ftp://user:password@10.10.2.100/Demo_Sync/" "option confirm off" "put -resume 1.7z" /log="C:\winscp.log" "exit"

When the connection brakes and gets re established I get the following error:

< 2015-01-25 19:57:30.419 150 Opening data channel for file upload to server of "/Demo_Sync/1.7z", restarting at offset 1773515
< 2015-01-25 19:57:30.420 550 can't access file.
. 2015-01-25 19:57:30.421 Copying files to remote side failed.
* 2015-01-25 19:57:30.421 (ExtException) **Copying files to remote side failed.**
* 2015-01-25 19:57:30.421 can't access file.

The -resume switch is used but the process cannot complete.

If I use e.g. FileZilla client resume of the same file on the same server is possible.
The server is a FileZilla FTP server and resume is enabled.
Do I miss something?

Attached you can find the complete log of the procedure.

Please attach a log from FileZilla.

Off-topic: Note that your command-line syntax is wrong. You cannot put the /log switch in between script commands (put and exit).

Hi Prikryl,

Attached the log from FZ server.
Just reproduced issue.

P.S. What would be the correct syntax?

I've meant a log from the FileZilla client.

For example:
start /min winscp.exe /console /command "option batch on" "open ftp://user:password@10.10.2.100/Demo_Sync/" "option confirm off" "put -resume 1.7z" "exit" /log="C:\winscp.log"

Thanks for your reply.

Any proposal on how to proceed in order to be able to successfully manage resume via WinSCP?

I'll try to implement the REST command. But it take some time.

This will be great.

I am trying to implement a vessel to shore upload solution over satellite data connections.
This is the only thing missing to have it up and running!!!

Re: (ExtException) **Copying files to remote side failed

Some more troubleshooting shown that if I break the transfer hitting CTRL+C in the winscp console and then I re execute the script it resumes successfully from the target's offset.
No resume happens, when I break the VPN tunnel through which the client running the script access the FTP server.

During the VPN tunnel re establishment period the console tries to reconnect as expected. When the VPN tunnel comes live again, winscp console succeeds to reconnect to the remote server but then gives the "unable to access file" I sent you.

Exactly the same happens when I use windows FTP append command which is rational:

ftp> append "C:\Users\usr\Documents\Scritps\1.7z"
200 Port command successful
150 Opening data channel for file upload to server of "/Demo_Sync/1.7z", restarting at offset 12178958
550 can't access file.

Actually Filezilla client does use REST to resume but I have to re-queue the file and restart the transmission manually from the client's GUI. There is no script automation for that. In both cases though brake occurs by braking the VPN tunnel. Filezilla client seems to be agnostic to the reason that broke the transmission and resume works fine.

I hope that the above helps you a bit more.

Losing VPN tunnel is the most common scenario I will face while trying to transfer files from the vessel to the office due to the satellite connections.
