MS SQL Server 2000... Error backing up database

Hi

I am getting an error while backing up a particular database named "asset" . The error says ......

Server: Msg 3132, Level 16, State 1, Line 4
The media set for database 'Asset' has 2 family members but only 1 are provided. All members must be provided.
Server: Msg 3013, Level 16, State 1, Line 4
BACKUP DATABASE is terminating abnormally.

I have created two backup devices for this database ("asset") through enterprise manager.
AssetDMP
AssetLogDMP

I have total 9 databases out of which only this database throws error. All other database backups going fine.

Here is the query that I am using to backup the database and Log.

USE master
GO
IF EXISTS (SELECT * FROM sysdatabases WHERE name = 'Asset')
BACKUP DATABASE Asset TO AssetDMP WITH NOUNLOAD, STATS=10, INIT, SKIP
GO
IF EXISTS (SELECT * FROM sysdatabases WHERE name = 'Asset')
BACKUP LOG Asset TO AssetLogDMP WITH NOUNLOAD, STATS=10, INIT, SKIP

Please Help

Thank You / SsgThis error occurs if a member of the stripe set (the backup was performed to more than 1 backup file/device) that was originally used to create the backup, was not selected when you tried to perform the restore. The number that displays in the message shows the set or file number that is missing.

You need to provide all the backup devices, files in your restore command|||Originally posted by Satya

Dear Satya,

Thanks a lot for your quick response. This issue has been resolved by re creating the devices ; but somehow I could not understand the root cause of the problem ;). Anyway, I wanted to ask one more question here...

I am using MS SQL 2000 Server. Can I move the dabases ( Master, Model , MSDB and tempdb) to a different drive location without re-installing SQL Server !!!

Waiting for an early reply...

Thanks again,
