NTBackup

NTBackup is the built-in backup application introduced in Windows NT around 1997 and part of all subsequent versions up to and including Windows 2000, Windows XP and Windows Server 2003. It uses 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. It also features integration with Task Scheduler and has several command line switches for scheduled automated backups.

In Windows Vista and later operating systems, NTBackup was replaced by Windows Backup and Restore Center, which uses the Virtual Hard Disk (VHD) file format, supports backup to modern media such as DVDs and image-based full system backups.

For server operating systems, Microsoft has replaced NTBackup with Windows Server Backup beginning with Windows Server 2008, which includes the new wbadmin command.. This new backup application, wbadmin, no longer supports tape drives, which means that users have to install third-party applications to backup to tape on these new operating systems (See for example ).

For reading/restoring older backups, Microsoft has made available the NTBackup Restore utility for Windows Vista/Windows Server 2008 and for Windows 7/Windows Server 2008 R2 which can only read BKF files.

When used with tape drives, NTBackup uses the Microsoft Tape Format (MTF) , which is also used by BackupAssist and Backup Exec and is compatible with BKF .

Features

NTBackup supports several operating system features including backing up the computer's System State. On computers that are not domain-controllers, this includes the Windows Registry, boot files, files protected by Windows File Protection, Performance counter configuration information, COM+ class registration database, IIS metabase, replicated data sets, Exchange Server data, Cluster service information, and Certificate Services database. On domain controllers, NTBackup can back up Active Directory, including the directory share.

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 normal, copy, differential, incremental and daily backups, backup catalogs, as well as Automated System Recovery. It supports logging and excluding files from the backup per-user or for all users. Hardware compression is supported if the tape drive supports it.

NTBackup can use removable media devices that are supported natively by the Removable Storage Manager (RSM) component of Windows. However, RSM supports only those tape devices which have RSM-aware WDM drivers and unless the tape device or other removable media device is recognized by RSM, it is not fully supported by NTBackup.

NTBackup from Windows XP and later includes Volume Shadow Copy (VSS) support and thus can back up . In case of Windows XP Home Edition, NTBackup is not installed by default but is available on the Windows XP installation disc. Windows XP introduced a wizard-style UI for NTBackup in addition to the advanced UI.

An expert system administrator can use the NTBackup scripting language to create a functional backup system. Scripting enables the system administrator to automate and schedule backups of files and system state, control the RSM to follow a media rotation strategy, reprogram the RSM to work with external HDD and NAS as well as tape, send email reminders to prompt users to insert the media and compile backup reports that include logs and remaining capacity. An alternative to scripting is GUI software such as BackupAssist, which automates NTBackup and can perform automatic, scheduled backups of Windows-based servers and PCs using NTBackup.

A third-party addon known as Firestreamer-RM extends the Removable Storage component in Microsoft Windows to support modern storage media such as external hard disks, flash memory, optical media such as CD, DVD and Blu-Ray and network file systems exposing the pieces of media as virtual tape to NTBackup which is based on Removable Storage.

NTBackup could be used under Windows Vista and Windows Server 2008 by enabling the Removable Storage Manager component in Turn Windows features on or off control panel and then copying the NTBackup files from a Windows XP machine. NTBackup can no longer be used on Windows 7 or Windows Server 2008 R2 as the Removable Storage Manager component has been removed in these operating systems.
