Removing Only One Piece of Media from a Backup from a Library

If you remove only one piece of media from a backup from a library, you may lose data. If you remove the first piece of media from a spanned save set and then select the delete media from system option in Removable Storage Manager for any of the other elements of that save set, all media belonging to that save set on the drive is erased. If you do not want to erase your tapes, keep all of your spanned save sets together.

Backup Fails to Start a Scheduled Job Because the Wrong Media is in the Drive

When an unexpected tape is mounted in the drive, Windows 2000 Backup does not start the scheduled backup operation. When Backup runs, it expects to write to a specific piece of media. If this media is not in the drive and you are not using a changer, the backup operation fails. No notification of this failure is provided because the backup operation is running without the user interface (UI). The backup log identifies the failure.

Backup Stops While Spanning Multiple Disks

When Windows 2000 Backup encounters a write-protected disk while spanning multiple disks, it stops running. As a workaround, make sure that none of the media using for the backup operation is write-protected.

Backup Shows Incorrect Elapsed and Estimated Times

Windows 2000 Backup shows the elapsed and estimated times incorrectly. No workaround is available at this time. You can ignore the displayed time.

Backup Cannot Detect If a Remote Drive Is Removable

Windows 2000 Backup cannot detect if a remote drive is removable. It assumes that all mapped drives are fixed disks. If a removal storage device (for example, a Jazz drive) is located and shared from another computer on the network, and the remote device is mapped to the local computer, Backup does not detect that the device is removable. As a workaround, do not map a remote drive that is removable. Instead, perform the backup operation to a remote hard disk, and then copy the files to the removable media.

Restore Does Not Recognize Media When Spanned Across Different Formats

The restore operation does not recognize media when it is spanned across different formats. If you restore data that has been spanned across several pieces of media and if the file systems differ across the media (for example, some media are in NTFS and some are in FAT), the restore operation does not recognize some media as being part of the backup set.

Backing Up to an 8-mm AME Tape on an Exabyte EXB-220 Changer

When you back up to 8-mm AME tape on an Exabyte EXB-220 changer, Windows 2000 Backup reports a “write file mark” failure. You should upgrade this firmware to the latest 6.4.3 version.

Files Located at the End of a Large Backup Set

Files that are located at the end of a large backup set may not restore. This can affect millions of files on data volumes larger than 100 GB. As a workaround, you can use independent software vendor (ISV) backups that use autoloaders. Alternately, run your backup operation in segments (start lower in the volume tree).

Backup Restores Some Additional Files from Remote Storage Media

Windows 2000 Backup restores some additional files from Remote Storage media. When Backup is used to restore tapes created by Remote Storage, additional files may be created. Remote Storage Manager uses these files, and they have no value outside of the this system. No workaround is available at this time. You can ignore these files.

Path Names Greater than 1000 Characters in Length

When path names are greater than 1000 characters in length, an access violation occurs in NTBackup.exe. Avoid using long path names for restore operations.

Restoring an Encrypted File

that has a File Hard-Linked to it

Restoring an encrypted file that has a file hard-linked to it destroys the link to the original file. You must manually re-link the file after the restore operation is completed.

Running Backup over Terminal Services

When you run Windows 2000 Backup over Terminal Services, some settings may get confused. Backing up drive letters that are mapped on both the local computer and the remote computer may cause Backup to stop responding at the prompt (Task Manager) for scheduled backup operations.

Restoring Exchange

If you attempt an Exchange restore operation, the Exchange Service must be running. If this service is not running, no options display for the Exchange restore operation.

Performing a Complete System Restore

If you perform a complete system restore operation from tape, you must first complete a minimal installation of Windows 2000 in the same directory as the previous installation. If the directory or drive is different, the system restore operation fails. Note that clean installations do not allow an installation location other than the default directory. In the case where the previous installation was not in the default \Winnt directory, you must complete a second, minimal installation in the non-default location. If there is one installation already on the hard disk, Setup prompts you about whether you want to overwrite the current installation or install to an alternate location.
