Backup Your Important Data..... Why ?
Back up your data before it's too lateSadly, many individuals and even businesses don't realize how valuable their data is until they don't have it any more. It's not a matter of "if" you will experience data loss; it's a matter of "when".
It could be a simple file deletion or it could be a disaster where we have to bring the system + data. Who knows what will happen within next few hours.
If you needs to have comprehensive backup solution you can go for third-party backup tools which will cover later in this post.
Or you could use free backup utility which come with the OS, also cover later in this post.
It is very important to backup your data either using by free or third-party backup tool before it is too late....
What are the third party backup tools?
Here I am mentioning some tool which I have experience on. The product prices are based on the backup strategy. for example if you are using the product to backup Exchange/ SQL /Oracle you need to have license for each in order to have comprehensive data recovery solution.

PC Tools - File Recover™
What is File Recover?
File Recover allows you to recover critically important documents, or other files, which have been lost by accidental deletion. These files may be lost by emptying the Recycle Bin, or using other deletion actions that bypass the Recycle Bin altogether. Such actions include Windows® Shift-Delete, command line deletion, deleting excessively large files or using applications that delete files without the Recycle Bin.
What happen to the Files after you delete them?
When a file is deleted from the Recycle Bin, or if the recycle bin is bypassed altogether, the file can no longer be recovered by the Windows® Operating system. The content of the file still remains on the drive, relatively intact, until the section of the drive it occupies is overwritten by another file.
How File Recovery recover your files?File Recover identifies the contents of such lost files on the hard drive and allows you to recover them. If a file has been partially overwritten, File Recover attempts to reconstruct as much of the file as possible with the remaining contents. This allows you to salvage at least part, if not all, of that recovered file to continue using it as required.
See how File recovery can save your important data once again.

Windows BitLocker Drive Encryption
BitLocker Drive Encryption
Windows BitLocker Drive Encryption is a new security feature that provides better data protection for your computer, by encrypting all data stored on the Windows operating system volume.
BitLocker uses the TPM to help protect the Windows operating system and user data and helps to ensure that a computer is not tampered with, even if it is left unattended, lost, or stolen.
To use BitLocker on a computer without a TPM, you must change the default behavior of the BitLocker setup wizard by using Group Policy, or configure BitLocker by using a script.
NOTE:
When BitLocker is used without a TPM, the required encryption keys are stored on a USB flash drive that must be presented to unlock the data stored on a volume.
How does BitLocker Drive Encryption work?
During the startup process, the TPM releases the key that unlocks the encrypted partition only after comparing a hash of important operating system configuration values with a snapshot taken earlier.
This verifies the integrity of the Windows startup process. The key is not released if the TPM detects that your Windows installation has been tampered with.
For enhanced security, you can combine the use of a TPM with either a PIN entered by the user or a startup key stored on a USB flash drive.
What is a TPM ?
A TPM is a microchip designed to provide basic security-related functions, primarily involving encryption keys. The TPM is usually installed on the motherboard of a desktop or portable computer, and communicates with the rest of the system by using a hardware bus.

Enabling AWE (Address Windowing Extensions) in SQL 2005
In Microsoft SQL Server 2005, you can use the Address Windowing Extensions (AWE) API to provide access to physical memory in excess of the limits set on configured virtual memory.
The specific amount of memory you can use depends on hardware configuration and operating system support.
By default SQL AWE setting is disabled, and need to be set following parameters to achieve this.
01) Windows Boot.ini configuration
/PAE (boot.ini)
02) Enable the Lock Pages in Memory Option (Windows)
Add SQL Service Account to "Enable the Lock Pages in memory" in Group Policy (Local)
03) SQL Configuration needs to be done in sp_configure
'AWE enabled' (sp_configure)
'max server memory' (sp_configure)
'min server memory' (sp_configure)

Linux FTP Server
Initial ConfigurationThe original configuration file for vsftpd is perfectly suited to a secure anonymous FTP server and makes a good basis to start customising,
It should be backed up to ensure any errors can be restored quickly from a known good file.
[bash]# cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.original
[bash]# vi /etc/vsftpd/vsftpd.conf
To display a welcome banner to every new user that connects, set the banner_file
banner_file=/etc/vsftpd/welcome.banner
This directive puts the FTP server into active mode for the data connection, the default is passive mode ("YES").
pasv_enable=YES
Starting The Server
Now that the FTP server has been configured, the runlevels should be set and checked to ensure the server will start as required.
[bash]# chkconfig --level 345 vsftpd on[bash]# chkconfig --list vsftpd
Controlling User Access
In vsftpd's initial state anonymous users are are allowed full download access to all the resources available through the FTP server, and adjustments to the configuration are required to enforce a more secure environment.
Anonymous UsersThe default setting for allowing anonymous users is YES. To disable anonymous access it is not enough to comment out the following parameter, it MUST be changed to NO, otherwise anonymous still has access.
anonymous_enable=YES
anonymous_enable=NO
If the FTP server is going to be accessible to the general public, then the anonymous account can be granted the rights to upload files to the server and create new directories inside the FTP root directory. Give serious consideration to these abilities before implementing them.
#anon_upload_enable=YES#anon_mkdir_write_enable=YES
Always avoid where possible, allowing anonymous users the ability to upload files to the FTP server. This has the potential to allow users of pirate software to abuse your system for further distribution. Always check the files on a regular basis for any sign of abuse.To restrict the upload rate of connected anonymous users, set the anon_max_rate to an appropriate value for your connection. The rate at which system account users can upload can also be restricted using the local_max_rate parameter.
Rates are in bytes per second, "0" is disabled.
anon_max_rate=10485760
local_max_rate=0
You may for some reason decide to limit the amount of users that connect to your server at anytime, and how many simultaneous connections can be maintained from each IP address.
max_clients=500max_per_ip=4

Ms Exchange 2007 Recovery
This article is covering how to recover crashed exchange server into a new server.
Understanding Setup /M:RecoverServer
One of the tools available for server recovery in Microsoft Exchange Server 2007 is the Setup /m:RecoverServer switch. Running Setup /m:RecoverServer on a server tells Setup to read the configuration information from the Active Directory directory service for a server with the same name as the server from which you are running Setup. The Exchange files and services are then installed on the server, and the roles and settings that were stored in Active Directory are then applied to the server.
 Note: |
Setup /m:RecoverServer is for recovery only. Do not use it as a repair tool, to recover from a failed install, to recover from a failed uninstall, or to reconfigure a server. It is only for recovering a server that was once fully functional, or to move a server to new hardware and maintain the same name.
|
| Important: |
Setup /m:RecoverServer cannot be used across operating systems. A server that was originally running Windows Server 2003 can be recovered only on Windows Server 2003, and a server that was originally running Windows Server 2008 can be recovered only on Windows Server 2008.
|
When You Should Run Setup /m:RecoverServer
There are several situations where the /m:RecoverServer switch can be of help to the Exchange administrator. Some of these situations are as follows:
- When your server is no longer available, and you must prepare a new or existing computer to replace the failed Exchange server. This could be situations where:
· Your hardware has failed.
· You are performing a dial-tone recovery, where Active Directory is intact.
· You are performing a site recovery, where Active Directory is intact.
- When migrating a Client Access server, Hub Transport server, Unified Messaging server, or Mailbox server to new hardware.
| Note: |
Setup /m:RecoverServer will only migrate setting information stored in Active Directory. Any local customizations or databases are not migrated with this method. For information about where Exchange stores data outside of Active Directory, see What Needs to Be Protected in an Exchange Environment.
|
| Note: |
If the virtual directories in Internet Information Services (IIS) have been modified, there are additional steps to migrate a Client Access server to new hardware. For more information about what needs to be backed up on a Client Access server, see Client Access Server Data.
|
When You Should Not Run Setup /m:RecoverServer
There are situations where it is not possible, or not a good idea, to run Setup /m:RecoverServer. Some of these situations are as follows:
- The Edge Transport server is not a supported role for the /m:RecoverServer switch. The Edge Transport server does not use Active Directory, so there is no setting information to be applied to the server from Active Directory. Instead of running /m:RecoverServer, you can install a new Edge Transport server and restore settings from backup.
| Note: |
The Edge Transport server includes a backup and recovery script to capture Edge Transport server configuration data. For more information about this script, see Using Cloned Configuration Tasks for Edge Transport Server Disaster Recovery.
|
- When the server information is no longer in Active Directory. If the server object is missing from Active Directory, there is no information that can be applied to the server.
- When a server with the same name as the server you are trying to recover still exists on the network.
- To repair a failed install. The Setup /m:RecoverServer option assumes a consistent configuration in Active Directory for the server. If Setup failed, the information in Active Directory might not have been fully written. In this situation, you should run Setup again.
- To change the availability configuration of your Mailbox server. You cannot run /m:RecoverServer to convert any of the following:
· A non-clustered Mailbox server into a clustered mailbox server, or vice versa.
· A single copy cluster into a cluster continuous replication Mailbox server or a non-clustered Mailbox server, or vice versa.
What to Do After Setup /m:RecoverServer Has Completed
Setup /m:RecoverServer restores the Exchange server configuration data from Active Directory, copies the Exchange files to the server, and sets default settings when alternate settings are not found in Active Directory. It does not restore customized settings that were stored on the server or end-user data stored in the Exchange databases on the server.
Each server role requires different post-recovery steps to bring it into a pre-recovery state. For a detailed list of items that need to be restored per server role, see What Needs to Be Protected in an Exchange Environment and read the topics that apply to each server role. In general, the following items must be restored:
- The mailbox and public folder databases on a Mailbox server. If the public folders on the server are all replicated on another server, you could create a new empty public folder database and backfill it from other replicas.
- Unified Messaging prompts and custom audio files on a Unified Messaging server, if the server was the prompt publishing point for a dial plan. Otherwise, the files are restored from the prompt publishing point server.
- If the database is not restored and a dial tone database is used, Unified Messaging users will need the following:
· A new personal identification number (PIN) must be issued.
· A new greeting must be recorded.
| Note: |
The audio recording of the user's name is stored in Active Directory. As long as Active Directory is intact, the recorded name will still be there.
|
- Any custom Office Outlook Web Access files or virtual directories on a Client Access server must be re-created.
- After you recover a Hub Transport server, there may be additional steps to perform such as:
· Restoring a saved queue database
· Enabling agents
· Configuring send connectors
If you are performing one or more of these tasks, the Hub Transport server should be stopped after a server recovery by default. Otherwise, the Hub Transport server will start with settings and agents in a backed-up state. The backed-up state might not represent what you had configured on the server right before the issue occurred that required the restore. Also, if you are restoring a saved queued database, you will need to place the database in the correct folder while the transport service is stopped. We recommend that you use the /DoNotStartTransport switch when restoring a Hub Transport server. The syntax for the command is as follows:
Setup /m:RecoverServer /DoNotStartTransport
- Any custom registry settings that were configured on the servers must be re-configured.
