Use Robocopy To Backup Files

robocopy C:\Users\username\Documents\ E:\Backup\ /MIR /XJD > Backup.log
echo "DONE" >> Backup.log

Dry Run:
robocopy C:\Users\username\Documents\ E:\Backup\ /MIR /XJD /L > Backup.log
rem  Copy files to backup volume
rem  /MIR - Mirror files (delete files on destination that aren't on the source)
rem  /XJD - Exclude junction points for directories (may cause infinite loops)
rem  /sl - Don't follow symbolic links and instead create a copy of the link.
rem  /FFT - 2 second difference when comparing timestamps
rem  /R:3 - Only retry 3 times (default is 1 million)
rem  /W:10 - Wait time between retries (default is 30)
rem  /Z - Copies files in restart mode (NOTE: This WILL slow down copying)
rem  /B - Backup mode - allows copy of open files (must run as Admin)
rem    NOTE: /Z and /B can be combined as /ZB
rem  /NP - Don't output progress of copy operation
rem  /log:backup.log - Logs to backup.log, overwriting old log file (use /log+: to append)
rem  /tee - Show output on console as well as log file
rem  NOTE: Use /L to do a "dry-run"
set roboargs=/MIR /XJD /FFT /R:3 /W:10 /NP /NDL /log:backup.log /tee
rem robocopy C:\source F:\destination %roboargs%
To do a full system backup to an external hard drive using the Windows 7 backup program (also available in Windows 8 and Windows 10) run the command sdclt.exe, and choose "Create A System Image".

How to make an HTTP request with PowerShell

If you are making an HTTP request to a RESTful web service, you can use the PowerShell  Invoke-RestMethod cmdlet. This provides a very simple HTTP REST interface, and will also format the result into a PowerShell object. If you would like to use your own functions, you can follow the instructions below. This is a helper function to format (indent) an XML response from a web service. function Format-XML { Param ([string]$xml) $out = New-Object System.IO.StringWriter $Doc=New-Object system.xml.xmlDataDocument $doc.LoadXml($xml) $writer=New-Object system.xml.xmltextwriter($out) $writer.Formatting = [System.xml.formatting]::Indented $doc.WriteContentTo($writer) $writer.Flush() $out.flush() Write-Output $out.ToString() } Here is the function to make the http call. It dumps the response data on the terminal and also returns it as a string to the caller. If there is an error it will dump the HTTP status code and comment on the terminal and return the re...

A simple IIS HTTP module to log request headers and post data

This is a simple http module that hijacks the incoming request and logs it to a file. Using this module prevents the application from getting the post data because the input stream can only be read once. With .NET 4.0 the module could be much smaller, and could allow the application to read the data. To compile this, create a new "Class Library" application called PostDataLogger. Most of this class is pieced together from stolen code (stack overflow, etc.) using System; using System.IO; using System.Web; /// /// Dump PostDataLogger.DLL in your bin, and put this in your web.config inside of /// /// /// /// public class SimpleLogger : IHttpModule { private HttpApplication _ctx; public void Init(HttpApplication context) { _ctx = context; context.BeginRequest += new EventHandler(Context_BeginRequest); } void Context_BeginRequest(object sender, EventArgs e) { string GUID = Guid.NewGuid().ToString(); string filename = @"d:\temp\adeber...
