I Dont Have Any Backup Of My Database, But I Have The Mdf's And Ldf's Files
Jul 23, 2005
Im trying to recover my database using the mdf and ldf files.
I dont have any backup and i have recovered two of the mdf files using
a tool which "discovers" deleted files after hard drive formatting...
It sounds cool, isnt it...:? :(
Obviously, i get a "suspect" message when the server starts and the log
file says this kind of things:
·"Full PathName.MDF is not a primary database file." (This is one of
the files repaired using the magic tool.
·Error: 823, Severity: 24, State: 6
·"I/O error (torn page) detected during read at offset
0000000000000000 in file 'Full PathiName2.mdf'... Name2.mdf is the
second file
·Device activation error. The physical file name 'Full PathName2.mdf'
may be incorrect.
When i try to execute the command "DBCC CHECKDB ('Database_Name') WITH
PHYSICAL_ONLY" i get the following message :
·Could not open FCB for invalid file ID 0 in database 'Logs'.
Do you have any ideas?
Thank you very much...:D

I do weekly full backups of my SQL databases via a scheduled T-SQL job.I noticed that I have some static databases that dont normally change,so I dont want to back it up if it has not changed, but when it does,then I want a backup.Is there something in the master table, as example, that I can checkprior to running the backup that will indicate any changes?An example is the Northwind database. I could exclude it from thebackup, but then I would not back it up if it where to change. Againthis is an example, I would not need to modify Northwind.Thanks in advance for any ideas; they usually give me ideas to problemsyet to come....Rob Camarda

I am doing a complete backup on a sql 7 db and then doing a completerestore (with overwrite existing db) on a sql 2000 server. This is nowour hot standby server. I have the process automated and it worksgreat. The only problem I have now is the logins dont work.I have tried running EXEC sp_change_users_login 'Report', and thelogins appear.However, when I run EXEC sp_helplogins 'joe', the results are empty.So, I am guessing all I need is a sp that will re-associate my loginswith the correct db and grant the appropriate permissions.If anyone has any ideas that would be great.I have also considered doing a log ship instead of a full backup andrestore. Does anyone have any suggections or good examples of how tomake that happen?Thanx

Hi,
I am developing a tool that takes snapshot of a particular database.
By snapshot I mean, attaching the .LDF & .MDF files.
Would you please let me know how to access these files & take a backup of the same.
And also how to restore them back. (using c# programming)
Thanks,
Archana A.A.

I am but a lowly DBA unworthy of this task...
I have a large (200+ GB) database with many (100+) files. Please don't ask me why I did it this way; I inherited this database -- really, it wasn't my idea.
My predecessor also seemd to think that backups were unnecessary; there have been no backups of this database -- ever.
While we cast about for a good long term solution, I am trying various short-term options. One I want to explore is to back the database up in chunks -- ie, by backing up individual files. I created a test database with five files (there is only one filegroup on the production server). Here is the DDL:
-- =============================================
-- Create database on mulitple file groups
-- =============================================
IF EXISTS (SELECT *
FROM master..sysdatabases
WHERE name = N'MultiFile')
DROP DATABASE MultiFile
GO
CREATE DATABASE MultiFile
ON PRIMARY
( NAME = MultiFile,
FILENAME = N'e:MSSQLDataMultiFile.mdf',
SIZE = 1MB,
MAXSIZE = 10MB,
FILEGROWTH = 10%),
( NAME = MultiFile2,
FILENAME = N'e:MSSQLDataMultiFile2.ndf',
SIZE = 1MB,
MAXSIZE = 10MB,
FILEGROWTH = 10%),
( NAME = MultiFile3,
FILENAME = N'e:MSSQLDataMultiFile3.ndf',
SIZE = 1MB,
MAXSIZE = 10MB,
FILEGROWTH = 10%),
( NAME = MultiFile4,
FILENAME = N'e:MSSQLDataMultiFile4.ndf',
SIZE = 1MB,
MAXSIZE = 10MB,
FILEGROWTH = 10%),
( NAME = MultiFile5,
FILENAME = N'e:MSSQLDataMultiFile5.ndf',
SIZE = 1MB,
MAXSIZE = 10MB,
FILEGROWTH = 10%)
LOG ON
( NAME = MultiFile_Log,
FILENAME = N'e:MSSQLDataMultiFile_Log.ldf',
SIZE = 1MB,
MAXSIZE = 10MB,
FILEGROWTH = 10%)
GO
I have tried the following backup script:
BACKUP DATABASE MultiFile
FILE = 'MultiFile',
FILE = 'MultiFile2'
TO Backup01
WITH
INIT
BACKUP DATABASE MultiFile
FILE = 'MultiFile3',
FILE = 'MultiFile4'
TO Backup02
WITH
INIT
BACKUP DATABASE MultiFile
FILE = 'MultiFile5'
TO Backup03
WITH
INIT
And here is the restore script:
RESTORE DATABASE MultiFile2
FILE = 'MultiFile',
FILE = 'MultiFile2',
FILE = 'MultiFile3',
FILE = 'MultiFile4',
FILE = 'MultiFile5'
FROM Backup01, Backup02, Backup03
WITH MOVE 'MultiFile' TO 'E:MSSQLDataaMultfile.mdf',
MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile2.mdf',
MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile3.mdf',
MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile4.mdf',
MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile5.mdf',
MOVE 'MultiFile_log' TO 'E:MSSQLaMultFile_Log.ldf'
However, running the Restore script generates the following error:
Server: Msg 3259, Level 16, State 1, Line 1
The volume on device 'Backup02' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set.
Server: Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
I'm not sure what to make of this. What do I need to alter in either the backup script or the restore script to make this work?
I am trying this because my objectives are to:
1. Limit the amount of work that the server is performing during any one given backup session. The idea that I have is to backup the database in chunks using a rolling 3-5 day window.
2. The database must be up and operational 7x24x365 (except for one 4 hour window each month)
3. This is not the long-term solution; but I need something to tide us over until we can purchase additional storage capacity.
I appreciate any thoughts and or guidance you can provide.
Regards,
hmscott

We have a pretty large SQL Server database, just shy of 400 GB. It is divided up into 24 different data files. The previous DBA here said it is faster to backup the backup individual data files to seperate files. So what he did was issue 6 backup statements like the one below as a step in an agent job.
BACKUP DATABASE MYDATABASE
FILE = 'Data',
FILE = 'data2',
FILE = 'data3',
FILE = 'data4'
TO Data1_4
WITH FORMAT
Next step:
BACKUP DATABASE MYDATABASE
FILE = 'data5',
FILE = 'data6',
FILE = 'data7',
FILE = 'data8'
TO Data5_8
WITH FORMAT
etc.. in sequence.
What I question is how this is faster than just issuing a backup for the whole database? Has anyone ever ran into this before?

I am trying to backup the sql database files from a local computer to a server location through vb.net 2005. Is there a simple way to do this? Every time I try to detach the database, I cannot because the database is in use. Is there something I am missing with this?

To all,How to backup a database into a number of smaller files ?For example, can I can fully backup a DB of 10 MB into 10 files (each 1MB)???The problem I've met is that the DB backup file is too large, over 4GB, and even Winzip can't compress it (after compressing, around 80 %of compression rate is possible)Thanks![color=blue]>From Jason (Kusanagihk)[/color]

We are having a problem with trying to backup the database device and log DAT files located in the MSSQLData directory.
The Seagate Backup Exec. states that the files are busy and skips them during its backup cycle. It skips all the devices in the
directory.
Any suggestions?

Hello,
I am attempting to restore the database from within VB.NET application I am making the following 3 calls:
RESTORE FileListOnly FROM DISK = 'C:MyDatabase.dat'
USE Master RESTORE DATABASE MyDatabase FROM DISK = 'C:MyDatabase.dat' WITH NORECOVERY, MOVE 'MyDatabase' TO 'C:Program FilesMicrosoft SQL ServerMSSQLDataMyDatabase.mdf', MOVE 'MyDatabase_log' TO 'C:Program FilesMicrosoft SQL ServerMSSQLDataLDFMyDatabase.ldf', REPLACE
RESTORE DATABASE MyDatabase FROM DISK = 'C:MyDatabase.dat'
using SMO. This logic works fine with small *.dat files, however when using *.dat file of about 4Gb I get an error on the 3d restore database call:
ExecuteNonQuery failed for Database 'master'.
An exception occurred while executing a Transact-SQL statement or batch.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Operator aborted backup or restore. See the error messages returned to the console for more details.

An exception occurred while executing a Transact-SQL statement or batch.

The same program/logic also works fine when I use MS SQL 2005 and it runs fine from MS SQL 2005 Query Analyzer for both 2005 and 2000 databases. There seem to be only problem with MS SQL 2000 from within VB.NET. Anybody has any idea? I'd appreciate any response. Thanks

To configure database mirroring
After connecting to the principal server instance, in Object Explorer, click the server name to expand the server tree.
Expand Databases, and select the database to be mirrored.
Right-click the database, select Tasks, and then click Mirror. This opens the Mirroring page of the Database Properties dialog box.
To begin configuring mirroring, click the Configure Security button to launch the Configure Database Mirroring Security Wizard.
but i do not see any "Mirror" Option in the "Tasks" menu.
Why ?

I have the need to delete old backup files via TSQL job. Found this solution online:
PushD "
emoteservershareDIFF" &&(
forfiles -m *DIFF*.sqb -d -1 -c "cmd /c del /q @path"
) & PopD
It works remotely if I run it via command prompt. But when I add this to a TSQL job on my remote SQL instance, it runs without deleting anything. What I'm missing?

Currently we use a SQL maintenance plan to do a full backup of all our databases daily (about 40 databases on our production server). As you can imagine, this eats up disk space quickly so currently we manually zip the backup files and/or move them to an archive drive. I considered writing an application to walk through the backup folder structure and zip any .bak file it finds, but I know there are some third party tools out there that will backup/restore a MS SQL database.
I was wondering if any of these also zip the backups once they are created. Any recommendations or suggestions are welcome.

I tried by using
RESTORE DATABASE <DATABASENAME>
FROM DISK = 'D:DATAMYTEST.DAT_BAK'
WITH MOVE 'VZAI_DATA' TO D:PROGRAM FILES..MSSQLTEST.MDF',
MOVE 'VZAI_LOG' TO D:PROGRAM FILES..MSSQLTEST.LDF',
REPLACE
And also i tried like
RESTORE DATABASE <DATABASENAME>
FROM DISK = 'D:DATAMYTEST.DAT_BAK'
WITH REPLACE
When i use like this,
RESTORE FILELISTONLY FROM DISK = 'D:DATAMYTEST.DAT_BAK'. I am able to get the output as LogicalName, PhysicalName, Type, FileGroupName, Size, etc.
Can i anyone please help me out?
Thanks in Advance,

Hi there
I'm getting this message on my third automated backup of the transaction logs of the day. Both databases are in full recovery mode, both successfully backed up at 01.00. The transaction logs backed up perfectly happily at 01:30 and 05:30, but failed at 09:30.
The only difference between 05:30 and 09:30's backups is that the log files were shrunk at 08:15 (the databases in question are the ones that sit under ILM2007, and keeping the log files small keeps the system running better).
Is it possible that shrinking the log files causes the database to think that there hasn't been a full database backup?
Thanks
Jane

hello! can you take a look at my question?
We use ARCServe to backup exchange server file (priv1.stm and priv1.edb) every night. When I select both of the files and start to back up using ARCServe. It showed me that Backup Operation Successful.
When I check the files, it didn’t backup both of the files. I don’t know why. Do you know how to backup these two files?
Many thanks.

Hi,We are about to install MSSQL Server 2000, on a Windows XP HomeMachine. However, we have servers we could set routine backups of filesto be done to. What what be the best way of doing this?Is there functionality in SQL Server 2000, where we can say dump alldata definitions, accounts, and data to files on this drive at regularintervals?What other suggestions do you have apart from obviously the usual RAID,and Tape Drive stuff?ThanksDavid

Hi All,I searched the archives but I could not find any useful stuff for me.I can backup a database on SQLExpress like USE masterEXEC sp_addumpdevice 'disk', 'Store_1', 'c:Store_1.dat'BACKUP DATABASE Store TO Store_1Here is my problem: If I use logins,roles etc. in an application automatically a mdf file is created. Or I can create a new sql database. SQLExpress dynamically use the mdf file when connection string defined. This mdf file is not defined as a database on SQLExpress. Because SQLExpress has not a gui, I cannot see the registered database. How can I backup any sqlexpress mdf file without deattaching or attaching?Thanks

hi
I have had trouble with maintenance plans not deleting expired backups, & this filling the hadrdisk. i have now done an agent job using tsql backup with init/skip, so it just overwrites. problem now is that it fails saying the backup device isnt available (cant delet the file from OS either) - so this was obviously the prob with the maintence plans too - sql/os doesnt seem to be releasing the file after it is completed and a server restart is needed to release it...
anyone know how to sort this?

When a new scheduled job is created for a Differential backup, the file specified in the Destination folder is automatically created by SQL Server. After the first time the job runs, is there a way to configure SQL Server to give each Differential file a unique name, including the timestamp (i.e. similar to Full Backup jobs)? I noticed my only options are 'Append to File" and "Overwrite Existing File." If I choose to enable "Backup Set Expiration," the backup job will not run, because it wants to append/overwrite the filename specified.
