Since I couldn't find any on the interwebs, some monitoring lead to.

Backup Folder Security to CSV with Powershell

thanks to whoever I stole the rescurse depth limit from :)

# Get the folder security and save it to csv

# -------------------------

$Date= get-date -Format yyyyMMdd

#Group path already includes two '\' so add 2 to folder level required

$Depth=3

# Obtain the files

$Rfolders=Get-ChildItem E:\group -recurse -Attributes Directory | % {$_.FullName.ToString()} | foreach {$var=$_;$count=(0..($_.length - 1) | where {$var[$_] -eq "\"}).count;if($count -le $Depth) {$_}}

# Obtain the folder security information and log to file

$LogFile = 'E:\group\GroupSecurityBackup_'+$date+ '.log'

$Rfolders | Get-Acl | Export-Csv $LogFile -Force

# Restoring individual folder

#--------------------------

# 1st- Import Acl back

 $ResFolder = import-csv E:\group\GroupSecurityBackup_<date>.log

#

# 2nd- Check acl for a specific folder

$Resfolder |Get-Acl | where {$_.path -like "*E:\group\test1\test2"}

#

# 3rd- To restore acl for a specific folder (this example we are exporting to another folder)

$acl = get-acl E:\group\testme

$acl.SetSecurityDescriptorSddlForm(($Resfolder |Get-Acl | where {$_.path -like "*E:\group\test1\test2"}).sddl)

set-acl E:\group\testme $acl

# Restoring Complete Tree Rebuld and ReSecure

# ---------------------------

$ResFolder = import-csv E:\group\GroupSecurityBackup_<date>.log

 foreach ($folder in $ResFolder) {

   write-host $folder.Path

   mkdir $folder.Path

   $acl = get-acl $folder.Path

   $acl.SetSecurityDescriptorSddlForm($folder.Sddl)

   set-acl $folder.Path $acl

   } 

powershell test file date time

$testfile="d:\temp\testflie_"+(Get-Date -Format yyyyMMdd-HHmm).ToString()+".log"

result
d:\temp\testflie_20130506-1735.log
