But when no copy of data is available, you should repair bkf by using third-party tools.

NTBackup.exe tool is a part of all Windows NT versions including Windows Server 2003, XP and 2000. The proprietary file format that it uses to backup the data is BKF.

I think that Windows XP is a very good Operating System, but long time usage can damage your registries, some malware can corrupt critical Windows files which makes your Windows almost impossible to use in time. When this happens it’s better to have a rescue solution. And happily there are a few methods to accomplish it, but I want to talk about Automated System Recovery Wizard (or ASR method) which comes with Windows XP Professional itself. The reason is that you don’t need to install any specialized software and it is very easy to do.
The tools that you need are: a formatted floppy disk, the Windows XP Professional CD and some free space in a drive where you want to save the backup file.
The program is named BACKUP and it can be found in Start – Programs – Accessories – Backup. More quickly to access it is to type in Start – Run : ntbackup, which is the name of the this small program. After you start it and the welcome screen appears you select the Advanced Mode. In the Advanced Mode of the Backup Utility you have three alternatives to choose: Backup Wizard, Restore Wizard and Automated System Recovery Wizard. The first option is if you want to do a more detailed selection of the directories and partitions, for example if you have special documents located elsewhere. The second is used to restore an already made backup. The third is used to create a clone of the entire Windows Operating System which is usually located on C:\ partition. If by any chance your OS is located elsewhere (another drive) you can select the first option and choose manually from the drives.
If you choose Automated System Recovery Wizard you are prompted on the next screen only about the location of the backup file where it would be created. You are free to decide about the name and the destination of this file. It requires only to have enough free drive space. Completing the Automated System Recovery Preparation Wizard is just the final stage. When you click on Finish the program will begin processing and then the backup operation will begin. The backup is made in one file which has the *.bkf extension. The process can take about 10 minutes but could be also less. After the image of the operating system is completed you are prompted to insert the floppy disk. This is used if your system fails to boot and you must boot from the Windows XP installation CD. The diskette will help you start the rescue program and restore the backup image.
When all it’s done you can remove the floppy from it’s drive. You can also do scheduled automated backups with Schedule Jobs.

As all type of data prefer, for their protection and preventing from loss, their backup is necessary. Exchange Server, which is the highly used enterprise solution, also needs protection from being corrupt and online and offline backups offer them the best for it. Though Exchange Server repair solutions are always there to cure the corruption, but the backup is considered safe for unspent restoration. Let’s talk about Exchange server backups in brief.
Online Backup: Being the stable method of Exchange server recovery, the method is preferred for taking database as the whole. But, always remember the fact that none of the backup software which is not Exchange-aware will prove fruitful for the job.
With NTBackup.exe, the task is safe to perform as with the installation of Exchange Server, the setup makes this backup program Exchange-aware. Whereas, if you desire to use some third party software for the same, take care to have extension, else you will be in big loss.
Most of the backups are scheduled, so if the failure happens after few hours of the specified time, the transactions in the interval have the chances to get lost if the transaction logs also get corrupt.
Offline Backup: For Exchange Server like applications, which is quite dynamic in nature, the offline backup solutions are not so worth and even not practical. This has many downsides like database is required to set offline while the backup process is in place and hence it becomes completely inaccessible for the mean time.
These types of backups are preferred when you need to migrate to any other server. Here the restriction of software being Exchange-server is not there as file level backup takes place.
Now, this is not sure that at time of failure, you retain the backup in good state. EDB recovery may not be welcomed through these backups. Moreover, some of the users may have not taken the backups till. So, in any of the case, whether the backup is not fruitful or the backup has not been implied till, EDB repair is the way which can scan and repair the corrupted database.
You can apply Exchange server recovery utilities on the ashes of the database to get the valuable results. These products are quite safe and good for Exchange server repair with the great options.
