 * Hi zoidberg,
 * I do have some simple checks to update the web.config file. However once your
   done running an install you will need to manually check your IIS and probably
   do some minor tweaking. I haven’t really done much testing with IIS since such
   a small amount of people use it.
 * However I am looking for some volunteers to help me finalize the documents and
   FAQs for what needs to be tweaked in order to finalize the process. I do have
   it on the todo list, but its a bit lower down…
 * With the 500 server error sometimes that issue is related to permission issues
   or a redirect, you might probe that path first…
 * Hope that helps!

 * I can tell you categorically that Duplicator works with Microsoft IIS.
    I have
   successfully backed up a domain on Windows 2008 IIS 7 and restored it to another
   domain. WordPress 3.3.2
 * Once you figure it out, it works very well.
 * You have to run PHP 5.3 or later. Also, if you don’t manually create the wp-snapshots
   folder in the root directory, you will get a permission related error. Even when
   the folder exists you get a permissions error but it does continue to successfully
   backup the site.
 * Warning: chmod(): Permission denied in […]wp-content\plugins\duplicator\inc\functions.
   php on line 324
    09:26:57 log:fun__create_snapshotpath=>error setting wp-root
   folder to 755. This process may need to be done manually.[…]/ 09:26:57 log:fun__create_snapshotpath
   =>success setting 755 for: D:/blah-blah/wp-snapshots
 * A 500 server error is usually either a permission problem or a missing folder
   OR some PHP extension (like a zip functionality) is missing.
 * I’m just about to test a backup on an Apache server and restore to a Windows 
   server.

 * Hey muddg,
 * Thanks for the feedback! I’m working a much better validation screen for the 
   next release. I’m hoping it will provide much better feedback about a given server
   environment, so that the process won’t start till everything is configured.
 * Hope to be released within the next month…
