SharePoint 2010 Network Load Balancing

In an effort to make my web front end severs a little more redundant, I introduced Windows Server 2008 R2 Network Load Balancing to my environment. After configuring the environment as per Microsoft documentation, I was not able to connect to the virtual IP I'd setup for my test site collection. After banging my head against the wall and rebuilding the servers a couple of times, I opened a ticket with Microsoft.


It turns out that you can't use NLB in the recommended unicast configuration if your cluster nodes are on two separate VMWare ESX hosts as per this article: http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1556&sliceId=1&docTypeID=DT_KB_1_1&dialogID=26310418&stateId=0 0 26304946


To learn more about the potential problems you might encouter if you use Cisco switches, have a look at the following:

And from Microsoft:

In the end, I reconfigured the NLB nodes to use Multicast mode and then utilized the Cisco documentation to create a static entry for the MAC of the NLB cluster virtual IP at the local gateway.

DocAve Version 5 for SharePoint 2010

Up until recently I've been running my backups using the built in backup and recover tool and Powershell (see http://imperfectit.blogspot.com/2010/03/automate-sharepoint-2010-farm-backups.html), but my environment has started to grow and become more complex. That, and it's larger than the recommended 150 GB limit "suggested" by Microsoft. As a result I had to find a more robust data protection solution. After much testing I went with AvePoint's DocAve v5.

DocAve Backup and Recovery for SharePoint 2010 offers two types of backup and recovery: Granular and Platform


Granular Content and Data Protection

• Supports SharePoint 2010, Microsoft Office SharePoint Server (MOSS) 2007 and Windows SharePoint Services 3.0 environments (via DocAve v5), and SharePoint Portal Server 2003 and Windows SharePoint Services 2.0 (via DocAve 4.5). Support for SharePoint 2001 is available – please contact an AvePoint representative).

• Full fidelity backup and restore of all lists, libraries and items (including Events, Links, Tasks, Contacts, Announcements, Discussion Boards, Surveys, Issues, Custom Lists, Areas, Sub Areas, Portal Links, Workflow Definitions, Layout Templates, and Site Definitions, along with access permissions, metadata and version histories)

• Backs up and restores SharePoint workflow definitions

• Full fidelity item-level restore from DocAve, SQL native backups created by T-SQL script or a maintenance plan, DPM, IBM-TSM, HP Data Protector, as well as third-party embedded SQL backup engines, including HyperBac and LiteSpeed Engine

• Granular, item-level restore with sliding timeline view, along with full text keyword search and identification criteria mask search

• Restore content to different SharePoint instances or locations, including file systems and networked file shares with DocAve's "out-of-place restore" functionality

• Manual and Automated Data Pruning feature helps manage historic SharePoint backup data and improve access speed to more recent backups

• Data Coalescing feature allows collapsing incremental backups into one backup data set for easy retrieval.

• Item-level "out-of-place restore" for complete hardware failure

• Fast granular backup speeds, up to 60GB/hour

Comprehensive Platform Protection

• Backup and recover entire SharePoint farms or selective components including all servers and back-end SQL databases with all configurations, Index/Job servers, as well as front-end IIS settings and file system resources

• Quickly and selectively restore individual or a combination of farm components (content databases, web applications, SSP, etc.)

• Safeguard front-end web server resources (IIS settings, Template files, user selected resources, local file systems, etc.)

• Backup InfoPath form templates, Project Server content and Site Definitions

• Support for SharePoint Features

• Up-to-the-minute restore using SQL logs restoration

• Leverages Volume Shadow Copy Service (VSS) to ensure consistent point-in-time backups

• Fast platform backup speeds, up to 100 GB/hour

• Efficient data streaming via open standards, including VDI and VSS without staging location requirements

If you've worked with this product or others, I'd be interested to hear your opinions.

Thanks!

SharePoint 2010 Anitvirus Exclusions

I recently updated the local antivirus on my SharePoint 2010 server and noticed users were getting "access denied" errors when trying to upload documents. Turns out I had forgotten to update the folders my antivirus solution should ignore.

A quick search turned up this: http://support.microsoft.com/kb/952167

Basically go to the drive you installed SharePoint 2010 on (D: drive in my case) and exclude the following:

Drive:\Program Files\Microsoft Office Servers\14.0\Data
Drive:\Program Files\Microsoft Office Servers\14.0\Logs
Drive:\Program Files\Microsoft Office Servers\14.0\Bin

The above folders handle indexing for your farm.
