Ho to use NTBackup In Server 2008 64bit with Exchange 2007 sp2

For months I have been trying to backup my exchange 2007 database,
Challenge being u just can convince management to buy all those nice but expensive tools that are available online en secondly we all know microsoft NTBackup (promising tool really) is no
longer available in windows server 2008.
Even after I had to install exchange service pack 2 I just could not figure out how I could do the VSS backup on an exchange installation that has the mail database within the same drive as operating system.
So I decided to search the net for a few answers (thanks to Google). I came across this article
NTBackup for Server 2008 with Exchange

Nway this is what you need to do is

1. Copying the following binaries from a server 2003 installation

(C:\Windows\System32\)
to a new location such as
(C:\Program Files\NTBackup\):
• ntbackup.exe
• ntmsapi.dll
• vssapi.dll

2. Install the removable storage manager from server manager:

• Start Server Manager•
Click Features
• Click Add Features
• Select Removable Storage Manager
• Click Install

3.Go into an older server (Windows server 2003) and copy esebcli2.dll from your server
(C:\Program Files\Exchsrvr\Bin)
and put it into your new location which in our case would be
(C:\Program Files\NTBackup\):
change the esebcli2 reg key (HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\BackupRestore\DLLPaths)
from
C:\Program Files\Micrsoft\Exchange Server\Bin\esebcli2.dll
To
C:\Program Files\NTBackup\ esebcli2.dll
Now go ahead and run your NTBackup utility (I know you want to)

Please Note
An incremental or differential backup cannot be performed on a storage group with circular logging enabled. Either perform Full backups, or disable circular logging in Exchange.

and

This article explains in details what circular logging is all about
However by default circular logging is disabled in Exchange

NOTE:
1.You will have to do one full backup before Exchange will allow you to perform any incremental
backups
2.You can view the back up status of your exchange mail db by going to
Exchange Management console->server configurations->mail box->right click on the storage
Group->Properties->General tab
