Upload file to SFTP using PowerShell

Question

We were asked to set up an automated upload from one of our servers to an SFTP site  There will be a file that is exported from a database to a filer every Monday morning and they want the file to be uploaded to SFTP on Tuesday  The current authentication method we are using is username and password  I believe there was an option to have key file as well but username password option was chosen    The way I am envisioning this is to have a script sitting on a server that will be triggered by Windows Task scheduler to run at a specific time  Tuesday  that will grab the file in question upload it to the SFTP and then move it to a different location for backup purposes   For example    Local Directory  C  FileDump SFTP Directory   Outbox  Backup Directory  C  Backup   I tried few things at this point WinSCP being one of them as well as SFTP PowerShell Snap-In but nothing has worked for me so far    This will be running on Windows Server 2012R2  When I run Get-Host my console host version is 4 0   Thanks

I am able to sftp using PowerShell as below:

PS C:\Users\user\Desktop> sftp [email protected]                                                     
[email protected]'s password:
Connected to [email protected].
sftp> ls
testFolder
sftp> cd testFolder
sftp> ls
taj_mahal.jpeg
sftp> put taj_mahal_1.jpeg
Uploading taj_mahal_1.jpeg to /home/user/testFolder/taj_mahal_1.jpeg
taj_mahal_1.jpeg                                                                      100%   11KB  35.6KB/s   00:00
sftp> ls
taj_mahal.jpeg      taj_mahal_1.jpeg
sftp>

I do not have installed Posh-SSH or anything like that. I am using Windows 10 Pro PowerShell. No additional modules installed.

You didn t tell us what particular problem do you have with the WinSCP  so I can really only repeat what s in WinSCP documentation   Download WinSCP  NET assembly  The latest package as of now is WinSCP-5 17 10-Automation zip   Extract the  zip archive along your script   Use a code like this  based on the official PowerShell upload example       Load WinSCP  NET assembly   Add-Type -Path  quot WinSCPnet dll quot       Setup session options    sessionOptions   New-Object WinSCP SessionOptions -Property          Protocol    WinSCP Protocol   Sftp       HostName    quot example com quot        UserName    quot user quot        Password    quot mypassword quot        SshHostKeyFingerprint    quot ssh-rsa 2048 xxxxxxxxxxx     quot          session   New-Object WinSCP Session    try             Connect        session Open  sessionOptions           Upload        session PutFiles  quot C  FileDump export txt quot    quot  Outbox  quot   Check         finally             Disconnect  clean up        session Dispose           You can have WinSCP generate the PowerShell script for the upload for you   Login to your server with WinSCP GUI  Navigate to the target directory in the remote file panel  Select the file for upload in the local file panel  Invoke the Upload command  On the Transfer options dialog  go to Transfer Settings  gt  Generate Code  On the Generate transfer code dialog  select the  NET assembly code tab  Choose PowerShell language   You will get a code like above with all session and transfer settings filled in    I m the author of WinSCP

There isn t currently a built-in PowerShell method for doing the SFTP part  You ll have to use something like psftp exe or a PowerShell module like Posh-SSH   Here is an example using Posh-SSH     Set the credentials  Password   ConvertTo-SecureString  Password1  -AsPlainText -Force  Credential   New-Object System Management Automation PSCredential   root    Password     Set local file path  SFTP path  and the backup location path which I assume is an SMB path  FilePath    C  FileDump test txt   SftpPath     Outbox   SmbPath      filer01 Backup     Set the IP of the SFTP server  SftpIp    10 209 26 105     Load the Posh-SSH module Import-Module C  Temp Posh-SSH    Establish the SFTP connection  ThisSession   New-SFTPSession -ComputerName  SftpIp -Credential  Credential    Upload the file to the SFTP path Set-SFTPFile -SessionId   ThisSession  SessionId -LocalFile  FilePath -RemotePath  SftpPath   Disconnect all SFTP Sessions Get-SFTPSession       Remove-SFTPSession -SessionId     SessionId       Copy the file to the SMB location Copy-Item -Path  FilePath -Destination  SmbPath   Some additional notes    You ll have to download the Posh-SSH module which you can install to your user module directory  e g  C  Users jon dechiro Documents WindowsPowerShell Modules  and just load using the name or put it anywhere and load it like I have in the code above  If having the credentials in the script is not acceptable you ll have to use a credential file  If you need help with that I can update with some details or point you to some links  Change the paths  IPs  etc  as needed    That should give you a decent starting point
