not able to take backup of a database

Hi Team, I have a database RECOV which has primary filegroup and i have added one more filegroup Test_group and added two secondary files sec_file_3.ndf,sec_file_4.ndf to this new filegroup. By using the following query i made one of the secondary file offline.


Now when i am trying to take backup of the database it is giving the following error

System.Data.SqlClient.SqlError: The backup of the file or filegroup "sec_file_3" is not permitted because it is not online. BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)

How to make the sec_file_3.ndf online?

Please help how to rectify the above problem for taking the backup of database

Thanks in advance......

A file should only be set offline when the file is corrupted, but it can be restored. A file set to offline can only be set online by restoring the file from backup. For more information about restoring a single file, see RESTORE (Transact-SQL).

If you have never performed a filegroup backup, or a full backup with this file - you will not be able to bring it back online. If you have performed a backup - you can restore the database and get the file back to online.

Another possible option is to drop the file and recreate the file (not preferrable if the file contains data).

I have backup which is taken before long time i.e. 4 months back. Now if i restore the database from old backup, i will loose the newly updated data in database. Already i dropPED the full text index on the table and finally deleted the table also. But still i can see entry in sys.master_files saying the file is offline and its type is FULLTEXT.In what way shall i proceed ?

Based on your comment, there is a second question and a second answer - IMO.



Check MSDN or BOL for the syntax.

Unfortunately, you can't do much. You're going to lose data someway.

Do you not have any file / file group backups?

If so, restore the db from the last FULL backup to a new db name and then restore the file / filegroup backups to see if that resolves the problem.

If you can't do that, then try backing up each filegroup individually (except the one that's offline). And restore those backups to the new database. You'll have to manually recreate the data and objects that exist in the corrupt filegroup onto the new database.
