Rsync is very useful, I don't have to copy all files in a directory. It updates only the newer files.
I use it with cygwin but I think there are some inconsistencies, which are not the main focus of this question.
so is there an equivalent?

Although not an exact equivalent, and not a Powershell feature, robocopy can do some of the things rsync is used for.

This works to synchronize directories between. Call the function "rsync ". i had permissions problems with robocopy. This doesn't have those issues.
function rsync ($source,$target) {
$sourceFiles = Get-ChildItem -Path $source -Recurse
$targetFiles = Get-ChildItem -Path $target -Recurse
if ($debug -eq $true) {
Write-Output "Source=$source, Target=$target"
Write-Output "sourcefiles = $sourceFiles TargetFiles = $targetFiles"
}
<#
1=way sync, 2=2 way sync.
#>
$syncMode = 1
if ($sourceFiles -eq $null -or $targetFiles -eq $null) {
Write-Host "Empty Directory encountered. Skipping file Copy."
} else
{
$diff = Compare-Object -ReferenceObject $sourceFiles -DifferenceObject $targetFiles
foreach ($f in $diff) {
if ($f.SideIndicator -eq "<=") {
$fullSourceObject = $f.InputObject.FullName
$fullTargetObject = $f.InputObject.FullName.Replace($source,$target)
Write-Host "Attempt to copy the following: " $fullSourceObject
Copy-Item -Path $fullSourceObject -Destination $fullTargetObject
}
if ($f.SideIndicator -eq "=>" -and $syncMode -eq 2) {
$fullSourceObject = $f.InputObject.FullName
$fullTargetObject = $f.InputObject.FullName.Replace($target,$source)
Write-Host "Attempt to copy the following: " $fullSourceObject
Copy-Item -Path $fullSourceObject -Destination $fullTargetObject
}
}
}
}
