Ans. BKF is known as "Backup Files". It is a built – in backup application used to create a proprietary backup format (BKF). It is also known as "Microsoft Tape Format" (MTF). It is a free utility available with Windows XP. Anyone can use it to take the backup of their valuable data from data loss situation. You can take backup of your files in Tape, Zip Drives, Floppy disks and Hard disks etc. This NTBackup utility supports Encrypting file system, NTFS hard links and junction points, alternate data streams, disk quota information, mounted drive and remote storage information. It saves NTFS permissions, audit entries and ownership settings, respects the archive bit attribute on files and folders and can create differential and incremental backups, backup catalogs, as well as Automated System Recovery.
A backup or the process of backing up files refers to preparing copies of data so that these copies may be used to restore the original after data loss event. Backup is the most important step to prevent data from data loss situations. There are two useful purposes of backup.

• Used to restore data in the situation of disaster (called disaster recovery).
• Used to restore small number of files in the situation of accidently deleted or corrupted due to any of the reason.

This is a default and can be renamed to any extension. This feature is not installed in "XP Home" by default. You can easily install it from the added value directory from CD of your "XP Home". After installing it you can use it to create a backup. You can take backup of your drives easily by using the NTBackup feature. Open Run and enter "NTBACKUP" command and press Enter and follow the instructions of the utility. If you make multiple backups then catalog of those backups is kept in your hard disk at "\Documents and Settings\All Users\Application Data\Microsoft\Windows NT\NTBackup\catalogs51  location.

Ans. A file backup is a copy of a file that is stored in a separate location from the original. You can have multiple backups of a file if you want to track changes to the file.

Ans. Backing up your files helps to protect them from being permanently lost or changed in the event of accidental deletion, a worm or virus attack, or a software or hardware failure. If any of those things occur and your files are backed up, you can easily restore those files.

Ans. You should back up anything that would be difficult or impossible to replace, and regularly back up files that you change frequently. Pictures, videos, music, projects, and financial records are examples of files that you should back up.

You don't need to back up programs because you can use the original product disks to reinstall them, and programs typically take up a lot of disk space.

Ans. It depends on the number of files you create and how often you create them. If you create new files every day, you might want to back up weekly or even daily. If you occasionally create many files for example, if you save a lot of digital photos from a birthday party or graduation, back them up right away. It's best to schedule regular, automatic backups so you don't even have to think about it. You can choose to have your files backed up daily, weekly, or monthly. You can also back up manually between automatic backups.

NOTE: The ability to set up automatic backups is not included in Windows VistaHome Basic; however, Windows will periodically remind you to back up your files.

Ans. The Back Up Files wizard backs up the most common file types. The following files are not included:

• Files that have been encrypted using Encrypting File System (EFS).

NOTE: If you are running Windows Vista Service Pack 1, EFS encrypted files are included in backups. EFS is not included in Windows Vista Starter,Windows Vista Home Basic, and Windows Vista Home Premium. For more information about installing Windows Vista Service Pack 1 (SP1), see Learn how to install Windows Vista Service Pack 1 (SP1).

• System files (the files that Windows needs to run)
• Program files
• Files stored on hard disks that are formatted using the FAT file system
• Web-based e-mail that is not stored on your hard disk
• Files that are in the Recycle Bin
• Temporary files
• User profile settings

Ans. That depends on the size of the files you back up. Windows keeps track of the files that have been added or modified since your last backup so you only have to update the existing backup, which saves disk space.

Ans. A backup or the process of backing up refers to making copies of data so that these additional copies may be used to restore the original after a data loss event. Backup is the most important step to prevent data loss. Backups are useful primarily for two purposes. The first is to restore a state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted. Data loss is also very common. 66% of internet users have suffered from serious data loss.

Since a backup system contains at least one copy of all data worth saving, the data storage requirements are considerable. Organizing this storage space and managing the backup process is a complicated undertaking. A data repository model can be used to provide structure to the storage. In the modern era of computing there are many different types of data storage devices that are useful for making backups. There are also many different ways in which these devices can be arranged to provide geographic redundancy, data security, and portability.

Users of Microsoft Windows have given in-built software for the backup of all the data. This process is quite useful and helpful in safeguarding the important data saved in the system. These MS backup files are created using the tool called NTBackup.

NTBackup is the built-in backup application to create a proprietary backup format (BKF) (also known as "Microsoft Tape Format" or MTF) to back up files. Files can be backed up to tape, ZIP drives, floppy disks, and hard drives. NTBackup supports Encrypting File System, NTFS hard links and junction points, alternate data streams, disk quota information, mounted drive and remote storage information. It saves NTFS permissions, audit entries and ownership settings, respects the archive bit attribute on files and folders and can create differential and incremental backups, backup catalogs, as well as Automated System Recovery.

This utility is not fault-proof as it also gets corrupted due to some unavoidable reasons like virus, improper system shutdown, power failure, etc. Sometimes, NTBackup corruption happens due to missing catalog files. In such situations, you may not be able to use the BKF file to restore your data at the time of data loss. Thus, in situations, you would be required to repair bkf file to retrieve and restore your data.

During the backup operation, catalog files are created and stored in the catalog folder on the system these appear under the NTBackup Restore tab. When you try to create more than one backup at the same time, these files share matching timestamp attribute. The backup set that was created first, is depicted in the Restore tab, but the other backups does not appear in the Restore tab. Such situations cause BKF file corruption.

BKF Recovery is the process of repairing and restoring damaged BKF file. This is potential through powerful and advanced third party tools that allow you to easily Repair BKF File.

SysInfoTools BKF repair is the fastest and efficient tool to recover BKF file in most of the cases. It works with BKF files created using NTBackup tool of Windows 2003, XP and 2000 and also the files created using Backup Exec by VERITAS software. It is compatible with Windows Vista/2003/XP/2000.

Ans. Demo version of the software reads corrupt BKF file and displays all files and folders in hierarchy from corrupt BKF files, but does not allow extracting or saving those files to the computer system. For saving your files, you need to purchase the full license.

Ans. Difference among the following three licenses:

• Single User License
• Administrator License
• Technician License

• This is meant for only one individual who is allowed to use the software only at one system for any of his non-commercial purpose in a non-business setting.
• Basically meant to be used in a homely environment for some private purpose.
• Allows converting of unlimited data files on a single machine only.
• Once the software in this license form is deployed on your system, it cannot be transferred to any another machine.

• Ought to be used either by any one person or one organization on multiple systems.
• Valid for only one single business unit in only one geographical location.
• Will be assigned to that organization name, which is furnished during the purchase.
• Permits to convert any number of files.
• The point to note here is that this license is not transportable from one business unit, where it was originally deployed to some other unit or department in any other geographical location.

• Software bought by the organization under an enterprise license can be used on multiple systems across any geographical locations.
• The name of the organization renders at the time of license purchase will be taken as the final name and therefore, the license will be assigned to that name only.
• The license owner is permitted to use the software for converting limitless files.
• Once deployed, you cannot transfer this license to any other organization.

Ans. YES, it can overcome from CRC (cyclic redundancy check) error. In fact it is designed to overcome such errors.

Ans. When you choose a location to save your backup to, the wizard searches your computer and displays a list of all locations that you can use. If the location that you want to use doesn't appear in the list, it could be due to one of the following problems:

• The location is a tape drive. You can't save backups to tapes.
• The location is the disk that you are trying to back up. You can't back up a disk to itself. For example, you can't back up the contents of drive E to drive E.
• The location is a CD-ROM drive. You can't use a CD-ROM drive to make a backup; you must use a CD burner, also known as a CD-R or CD-RW drive.
• The location is a USB flash drive. You can't save backups to a flash drive.
• The location is not formatted as NTFS, FAT, or Universal Disk Format (UDF) (also called Live File System). Backups can only be saved to disks that are formatted using the NTFS, FAT, or UDF file systems. For more information, see Comparing NTFS and FAT file systems.
• The location is either the system disk (the disk that Windows is installed on—also called the C drive) or the boot disk (the disk that Windows uses to start your computer—also called the startup disk).
• The location is a network share on a computer running Windows XP Home Edition. You can't save backups to these shares because setting permissions on network shares and authenticating over a network are not supported byWindows XP Home Edition.

Ans. Not unless your backup fits on one disc and the disc is in the computer when the backup starts. Otherwise, schedule the backup for a time when you will be available to insert the discs. Windows will notify you later that the backup wasn’t completed; you can then insert a disc to continue the backup.

Ans. If you run out of discs during a backup, you can finish later.

Ans. No. If your computer is turned off during the scheduled backup time, automatic backups will not run. However, the next time you turn on your computer, you will be able to back up your files and resume the normal backup schedule.

Ans. If your backups are saved to CDs or DVDs, you can discard discs containing earlier backups, but make sure that you keep the most recent backup of your files. If your backups are saved to an internal or external hard disk, you can delete a backup by following these steps:

1. Open the location where the backup is saved.

For example, if you backed up your files to an external hard disk labeled &E," connect the external hard disk to your computer, and then open drive E.

2. Right-click the folder containing the backup you want to delete, and then clickDelete.

• When you make a full backup, a backup folder is created and labeled with the date for that day. As you add updates, that date stays the same, but your backup is not out of date. The next time you make a full backup, a new backup folder is created and labeled with the date for that day, and any updates are then added to that new folder. You should not delete the current backup folder.

Ans. Method 1: Copy files from XP

• ntbackup.exe
• ntmsapi.dll
• vssapi.dll

First of all, run the file ntbackup.exe. When prompted, click on "Do not show this message again when warned that removable storage service is not running".
Now, NT Backup should run properly and you can open BKF files on Windows 7.

Microsoft offers a restore utility for Windows Vista and Windows Server 2008, but Microsoft removed the feature “Removable Storage Management” from Windows 7. So you will get the following error when you try to run the restore utility on Windows 7:

Anyway, Microsoft released an update/hotfix for Windows 7 and Windows Server 2008 R2 that allows you to open and restore BKF files in Windows 7. It won’t work on Windows 7 RTM or RC.
