Backup and Restore Instructions for the DirSync Database

Today, Microsoft released a 9 page guide on backing up and restoring the Microsoft Azure Active Directory Sync tool. You can get it here.

Some things to keep in mind:

  • This guide applies to DirSync when used with the full version of SQL only.  This means it does not apply to most installations.
  • You don’t need to backup or restore DirSync.  If you simply install a new instance and configure it appropriately, the objects will re-sync.  Doing a backup/restore can save time however, if you have a very large number of users (I wouldn’t bother with less than 100k).
  • Ironically, this guide doesn’t actually tell you how to backup or restore the database.  You need some SQL-aware backup product to do that.  Instead, this guide helps you make use of a restored database in a DirSync environment (working with miisclient.exe, handling keys, etc).
