SYMPTOMS
When you back up data from a volume by using the Backup program in Microsoft Windows Server 2003, the following information appears in the backup log file:

Error returned while creating the volume shadow copy:800423f4

Reverting to non-shadow copy backup mode.

Backup of &quot;C: &quot;

Backup set #1 on media #1

Backup description: &quot;Set created  at  &quot;

Media name: &quot;backup.bkf created  at  &quot;

Therefore, you cannot use Backup to perform a Volume Shadow Copy service backup of data from the volume.

Note This problem occurs even when you do not back up any SQL Server database information.

MORE INFORMATION
After you install this hotfix, you can use Backup to perform a Volume Shadow Copy service backup of the non-SQL Server data from a volume that contains a SQL Server database. This hotfix prevents Windows Backup from reverting to non-shadow copy backup mode when it encounters a SQL database with a recovery model that is not set to Simple. This hotfix does not let Windows Backup perform a Volume Shadow Copy service backup of a SQL Server database with a recovery model that is set to Full or Bulk-Logged. You must use the SQL Server backup procedure to back up your SQL Server databases that have a recovery model that is set to Full or Bulk-Logged. Additionally, when you use Backup to back up information from a volume that contains a SQL Server database file in non-simple recovery mode, the following information appears in the backup log file:

MSDEWriter has reported a VSS error 0x800423f4.

NtBackup does not support backing up SQL databases which are configured

in non-simple recovery mode.

If the database has been backed up, it is likely corrupted. Please do

not restore this database.

The recommended way of backing up non-simple SQL database is to use the

backup solution that comes with SQL Server.

The following warning will be logged in the application event log:

Description: MSDEWriter has reported a VSS error. NtBackup does not support backing up SQL databases which are configured in non-simple recovery mode. If the database has been backed up, it is likely corrupted. Please do not restore this database. The recommended way of backing up non-simple SQL database is to use the backup solution that comes with SQL Server.

This log file information is intended to notify you that you must use the SQL Server backup procedure to back up your SQL Server database files. All non-SQL Server data is backed up by using the Volume Shadow Copy service.

Using SQL Server 2000 backup

 * 1) Start SQL Server Enterprise Manager.
 * 2) Double-click Microsoft SQL Servers, double-click SQL Server Group, (Local), and then double-click Databases.
 * 3) Right-click each database, point to All Tasks, and then click Backup Database.
 * 4) In the Name box, type the backup set name. Alternatively, in the Description box, type a description of the backup set.
 * 5) Under Backup, click Database - complete.
 * 6) Under Destination, click Tape or click Disk, and then specify a backup destination. If no backup destinations appear, click Add to add an existing destination or to create a new one.
 * 7) Under Overwrite, use one of the following procedures:
 * 8) * Click Append to media to append the backup to any existing backups on the backup device.
 * 9) * Click Overwrite existing media to overwrite any existing backups on the backup device.
 * 10) Alternatively, click to select the Schedule check box to schedule the backup operation for later or for periodic execution.
 * 11) Alternatively, click the Options tab and do one or more of the following:
 * 12) * Click to select the Verify backup upon completion check box to cause the backup to be verified when it is backed up.
 * 13) * Click to select the Eject tape after backup check box to cause the tape to be ejected when the backup operation has completed.

Note This option is available only with tape devices.
 * 1) * Click to select the Check media set name and backup set expiration check box to cause the backup media to be checked. Doing this prevents accidental overwrites.
 * 2) * In the Media set name text box, type the name of the media that is to be used for the backup operation. Leave this text box blank when specifying only the backup set expiration.
 * 3) If it is the first use of the backup media, or if you want to change an existing media label, under Media set labels, click to select the Initialize and label media check box, and then type the Media set name and Media set description. The media can be initialized and labeled only when overwriting the media.

If you want to convert your SQL Server databases to Simple recovery model to let the Volume Shadow Copy service to back them up, follow these steps.

Setting the SQL Server 2000 database recovery model to Simple

 * 1) Start SQL Server Enterprise Manager.
 * 2) Double-click Microsoft SQL Servers, double-click SQL Server Group, (Local), and then double-click Databases.
 * 3) Right-click each database, and then click Properties.
 * 4) Click the Options tab.
 * 5) Under Recovery, set the model to Simple.

If you are using the Simple Recovery model, and you want more frequent backups of your SQL data, you can perform differential backups with your regular backups.

Creating a differential database backup

 * 1) Expand a server group, and then expand a server.
 * 2) Expand Databases, right-click the database, point to All Tasks, and then click Backup Database.
 * 3) In the Name text box, type the backup set name. Alternatively, in the Description text box, type a description of the backup set.
 * 4) Under Backup, click Database - differential.
 * 5) Under Destination, click Tape or click Disk, and then specify a backup destination. If no backup destinations appear, click Add to add an existing backup device or to create a new one.
 * 6) Under Overwrite, use one of the following procedures:
 * 7) * Click Append to media to append the backup to any existing backups on the backup device.
 * 8) * Click Overwrite existing media to overwrite any existing backups on the backup device.
 * 9) Alternatively, click to select the Schedule check box to schedule the backup operation for later or periodic execution.
 * 10) Alternatively, click the Options tab, and then take one or more of the following actions:
 * 11) * Click to select the Verify backup upon completion check box to cause the backup to be verified when backed up.
 * 12) * Click to select the Eject tape after backup check box to cause the tape to be ejected when the backup operation has completed.

Note This option is only available with tape devices.
 * 1) * Click to select the Check media set name and backup set expiration check box to cause the backup media to be checked. Doing this prevents accidental overwrites.
 * 2) * In the Media set name text box, type the name of the media that is to be used for the backup operation. Leave this text box blank when specifying only the backup set expiration.
 * 3) If it is the first use of the backup media, or if you want to change an existing media label, under Media set labels, click to select the Initialize and label media check box, and then type the Media set name and Media set description. The media can be initialized and labeled only when overwriting the media.
