Random Mirroring Facts

Today is a hodge podge of facts about mirroring, since I am in learning mode I thought I would share with you.

  • Mirroring is deprecated, meaning it is going away and moving to AlwaysOn availability groups.  Now is probably not the time to devise a mirroring plan.
  • You can mirror some or all of your databases on a particular instance.
  • You can only mirror databases in the FULL recovery model.
  • Mirroring supports only one principal and one mirror.
  • All versions support witness modes but only Enterprise supports high-performance mode.
  • Enterprise, Standard and the new BI version all support the high-safety mode.
  • You cannot mirror a database that is using FILESTREAM file groups.
  • You can only mirror user databases.
