Windows Server Backup – Can’t handle greater than 2TB Volumes

I have just discovered that Windows Server Backup on Windows server 2008 R2 is incapable of backing up any volume 2TB or over. This, it turns out, is due to a VHD file limit. Backup essentially creates a VHD for each volume in the backup, which is great for recovery, but causes this annoying problem.

The not very helpful message you will receive if you try a full server backup when one of the volumes is too large is

“Volumes larger than 2088958 megabytes cannot be protected.”


The work-around is to not do full volume backups, but make your selection of folders. Choose ‘Custom’ backup configuration and then just select all the folders on the volume that is too large.

SQL script to kill all connections to a SQL Server database

I have finally perfected a nice script for killing connections to databases. Although basic, I found many of the ones I google’d, had one problem or another that stopped them working straight away, which just wastes time. This one works! I have just used it.

Just replace the database name and it’s good. It is easy to alter it to work across a list of databases too.

DECLARE @databaseName VARCHAR(100)

-- Count Connections

from master.dbo.sysprocesses
where db_name(dbid) = @databaseName
 DBID <> 0

-- Create the sql to kill the active database connections

How to bulk unblock files in Windows 7 or Server 2008

In Windows 7 (actually any of the latest Windows releases) you will find that files copied to your local drives are not trusted until you right-click on them and in the properties click the ‘Unblock’ button. This is all very well for one or two files, but gets extremely tedious with more. It turns out to be related to NTFS’s ability to allow alternate data streams.

So here is a simple method of mass or bulk unblocking files.

  1. Download the Sysinternals Streams.exe from
  2. I find Sysinternals so useful I create a ‘SysInternals’ folder on my C: drive and then put this into my ‘path’ environment variable so that I can run them from anywhere. However, if this is too much then the easiest is to copy the streams.exe to the root folder you wish to have files unblocked.
  3. In a command windows (with Admin privileges), use ‘cd’ to navigate to your folder.
  4. Type the command ‘streams –s –d subfoldername’ and press enter.
