Traverse samba shares during robocopy and exclude some - powershell

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?

Answer 1

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)

Answer 2

remember \ is an escape character. Two \ equals 1 . Try using single quotes ' on your variable strings instead of double quotes "
That's why it's looking for \192.168.1.100\ instead of \192.168.1.100\
I'd also include share names if needed.
Single quotes will allow you to not need to escape. Example:
$Path = Split-Path '\\192.168.1.100\asuscloud\*'
$Dest = 'E:\back_fold\asuscloud\'
Using double quotes might need escaping. Example:
$Path = Split-Path "\\\\192.168.1.100\\asuscloud\\*"
$Dest = "E:\\back_fold\\asuscloud\\"
Please note you might need to escape the asterisk as well.
Including sharename (if needed). Example:
$Path = Split-Path '\\192.168.1.100\c$\asuscloud\*'
