Copy file remotely with PowerShell

Question

I am writing a PowerShell script that I want to run from Server A  I want to connect to Server B and copy a file to Server A as a backup   If that can t be done then I would like to connect to Server B from Server A and copy a file to another directory in Server B   I see the Copy-Item command  but I don t see how to give it a computer name   I would have thought I could do something like  Copy-Item -ComputerName ServerB -Path C  Programs temp test txt -Destination  not sure how it would know to use ServerB or ServerA    How can I do this

None of the above answers worked for me  I kept getting this error   Copy-Item   Access is denied   CategoryInfo            PermissionDenied     192 168 1 100 Shared test txt String   Copy-Item   UnauthorizedAccessException gt       FullyQualifiedErrorId   ItemExistsUnauthorizedAccessError Microsoft PowerShell Commands CopyItemCommand   So this did it for me     netsh advfirewall firewall set rule group  File and Printer Sharing  new enable yes   Then from my host my machine in the Run box I just did this      IP address of nanoserver  C

Simply use the administrative shares to copy files between systems    It s much easier this way   Copy-Item -Path   serverb c  programs temp test txt -Destination   servera c  programs temp test txt        By using UNC paths instead of local filesystem paths  you help to   ensure that your script is executable from any client system with   access to those UNC paths  If you use local filesystem paths  then you   are cornering yourself into running the script on a specific computer    This only works when a PowerShell session runs under the user who has rights to both administrative shares   I suggest to use regular network share on server B with read-only access to everyone and simply call  from Server A    Copy-Item -Path     ServerB SharedPathToSourceFile  -Destination   Env USERPROFILE  -Force -PassThru -Verbose

Just in case that the remote file needs your credential to get accessed  you can generate a System Net WebClient object using cmdlet New-Object to  Copy File Remotely   like so   Source      192 168 x x somefile txt   Dest      C  Users user somefile txt   Username    username   Password    password    WebClient   New-Object System Net WebClient  WebClient Credentials   New-Object System Net NetworkCredential  Username   Password    WebClient DownloadFile  Source   Dest    Or if you need to upload a file  you can use UploadFile    Dest      192 168 x x somefile txt   Source      C  Users user somefile txt    WebClient UploadFile  Dest   Source

From PowerShell version 5 onwards  included in Windows Server 2016  downloadable as part of WMF 5 for earlier versions   this is possible with remoting  The benefit of this is that it works even if  for whatever reason  you can t access shares  For this to work  the local session where copying is initiated must have PowerShell 5 or higher installed  The remote session does not need to have PowerShell 5 installed -- it works with PowerShell versions as low as 2  and Windows Server versions as low as 2008 R2  1  From server A  create a session to server B   b   New-PSSession B  And then  still from A  Copy-Item -FromSession  b C  Programs temp test txt -Destination C  Programs temp test txt  Copying items to B is done with -ToSession  Note that local paths are used in both cases  you have to keep track of what server you re on    1   when copying from or to a remote server that only has PowerShell 2  beware of this bug in PowerShell 5 1  which at the time of writing means recursive file copying doesn t work with -ToSession  an apparently copying doesn t work at all with -FromSession
