Traverse samba shares during robocopy and exclude some

Question

I use Robocopy for backup Samba shares into local drive and vice versa. To sync remote share with local folder I use PS script

$Path = Split-Path "\\192.168.1.100\asuscloud\*"
$Dest = "E:\back_fold\asuscloud\"
robocopy $Path $Dest /B /MT:64 /IS /Z /FP /MIR /TEE /NP /FP /NDL

To exclude some subfolder one can use /XD switch

$Path = Split-Path "\\192.168.1.100\asuscloud\*"
$Dest = "E:\back_fold\asuscloud"
robocopy $Path $Dest /B /MT:64 /IS /Z /FP /MIR /TEE /NP /FP /NDL /XD "\\192.168.1.100\asuscloud\subdir"

However, this syntax doesn't work for the host and shares of this host

$Path = Split-Path "\\192.168.1.100\*"
$Dest = "E:\back_fold\"
robocopy $Path $Dest /B /MT:64 /IS /Z /FP /MIR /TEE /NP /FP /NDL /XD "\\192.168.1.100\asuscloud\"

It throws

I want to exclude two shares of a host and sync others into local folder.

How to achieve this?

Is the list of SHARENAMEs on the remote computer a fixed list, or does it need to be dynamically found? — lit

This does not dynamically find the shares on the remote host, but it does allow you to specify the SHARENAMEs from which to copy.

I think your basic misunderstanding is that a hostname (or IP address) alone is not a path. It has to also have a SHARENAME.

If you save this as Do-It.ps1, then to see the verbose messages, invoke it with .\Do-It.ps1 -Verbose

[CmdletBinding()]
Param(
    [Parameter(Mandatory=$true, position=0)]
    [string]$computername

    ,[Parameter(Mandatory=$true, position=1)]
    [string[]]$sharenames

    ,[Parameter(Mandatory=$false, position=2)]
    [string]$dest = 'E:/back_fold/asuscloud'
)

$excludeshares = @('SHARE1', 'OTHERSHARE')

foreach ($sharename in $sharenames) {
    write-Verbose $sharename
    if ($excludeshares -notcontains $sharename.ToUpper()) {
        $Path = "//$computername/$sharename"
        $cmdline = { robocopy $Path $Dest /B /MT:64 /IS /Z /FP /MIR /TEE /NP /FP /NDL }
        Write-Verbose $cmdline.ToString()
        & $cmdline
    }
}

This can be use with a file containing a list of SHARENAMEs.

.\Do-It.ps1 -computername '192.168.1.100' -sharenames $(Get-Content -Path .\sharelist.txt)
