Often written off as a useless utility in the shadow of heavyweight tools such as ARCserve and Backup Exec, the Windows NT Backup utility is actually both beneficial and cost-effective.
For example, you can use NT Backup to back up an Exchange information store even while it's running and serving requests. In addition, installing Exchange management utilities on a server automatically extends the Windows NT Backup utility to enable it to handle Exchange databases.
This goes for more than just Windows NT. Windows 2000 and Windows Server 2003, as well as both Exchange 2000 and Exchange 2003, extend the versions of NT Backup installed on those systems to handle the same function.
When using a utility such as ARCserve or Backup Exec to back up Exchange databases, you need to either use an agent or back up the databases while they're offline. If your organization is short on cash but needs to back up Exchange data while it's online, use NT Backup to handle this task. If you use ARCserve or Backup Exec, you can then back up the file created by NT Backup during your regular backup process.
