  • Blog Post: Combining Disaster Recovery Farms with SQL Redundancy for SharePoint with SQL Server AlwaysOn

    Alternative title: “ how do I get a redundant SQL backend combined with a disaster recovery site, using AlwaysOn ”? This is a question that has come up a bit just recently so I though I'd clarify how this can work. Arranging the SQL Server AlwaysOn setup for SharePoint, especially when...
  • Blog Post: Synchronising Service Applications Between SharePoint Disaster Recovery Farms

    A key part of hot-standby/disaster-recovery SharePoint 2013 farms is the principal that only content is synchronised between the two farms. The reason being is that we want to reduce the chance that a failure will replicate over to the other farm too, so we just replicate content and keep services separate...
  • Blog Post: SharePoint Disaster Recovery Failover Techniques

    So you’ve got or are interested in two SharePoint farms running in parallel and you want to know how to switch users between the two farms for when you need to. There’s a few options to do it; choosing the right one largely depends on how quickly you need to be able to failover everyone, and to what...
  • Blog Post: Introduction to Running Disaster-Recovery/Hot-Standby SharePoint Farms

    So you’ve heard about the possibility of running two SharePoint farms in parallel to help keep SharePoint users happily online longer, and you want some more information about how it works and why you’d want it. This one is a nice and quick post on just the basics to sell the idea a bit - nothing too...
  • Blog Post: Patching SharePoint with No Downtime using SQL Server AlwaysOn

    As highlighted in a previous post , it is perfectly possible to patch SharePoint without suffering any downtime at all if you have x2 SharePoint farms to play with. This is great if you’re worried about the update process taking either too long for a maintenance window or not completing at all...
  • Blog Post: Setting up SharePoint Disaster Recovery Sites with SQL Server AlwaysOn

    Something I’ve been promoting as an essential high-availability strategy for SharePoint for a while now is having a Disaster Recovery (DR) site for SharePoint. A SharePoint DR site is simply an entirely separate SharePoint farm that uses a copy of the content data in case the first farm runs into...
  • Blog Post: Why Disaster Recovery Farms are Essential for High-Availability SharePoint

    It’s not uncommon for customers plan a highly-available SharePoint (HA-SP) installation to satisfy uptime requirements for the business. It is uncommon that said designs give an architecture in the best way for staying online always though, and this is what this post is about. The Normal High-Availability...
  • Blog Post: How to Patch a Single SharePoint Farm With Minimal any Downtime

    Having already blogged about this subject, a question I frequently get asked is “how can I patch my [single] SharePoint farm with no or minimal down-time?” Well let’s cut to the chase; it’s not possible to patch a SharePoint farm without any downtime , and the absolute minimum time you’re looking at...
  • Blog Post: Stretched SharePoint Farms vs. Disaster Recovery SharePoint Farms

    Something I want to clarify is the difference between these types of “high-availability” SharePoint setups. The difference is fairly simple actually but people often get the two confused so I thought I’d write something quick about the subject, because the two designs are not nearly...
  • Blog Post: SharePoint AD Failover Review

    A key part of the SharePoint high-availability puzzle is a healthy and highly-available Active Directory; if AD dies then so does your SharePoint farm too, broadly speaking. However more specifically, that opening statement should really say “each and every SharePoint server needs AD failover” for the...
  • Blog Post: SQL Server Log Shipping – Bandwidth Analysis for Content Database Updates

    A question that often comes up when talking about SharePoint and SQL Server log-shipping is “how much bandwidth will I need to make log-shipping work between my two farms?” It’s certainly a sensible question given these things need to be planned to avoid over-congestion preventing the Disaster-Recovery...
  • Blog Post: Managing Custom Solutions for Disaster Recovery SharePoint Farms

    Having x2 SharePoint farms that need to be synchronised perfectly does raise the question about how to maintain both farms updated with any custom solutions that may need to be applied to the farm/application. This guide is about how to maintain custom solutions across two or more farms and what can...
  • Blog Post: Hot-Standby/Disaster-Recovery SharePoint Farms with Log-Shipping

    Something that’s often required for high-availability SharePoint installations is the ability to failover to another web-farm entirely when needed because of a failure of some kind on the 1st farm, or wanted because of maintenance taking the 1st farm offline completely. Edit : If you want a...
