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 script the DROP(IF EXISTS) and CREATE for all of mytables, views, stored procs, and functions to individual SQL text files(one per object). This was trivially done in SQL 2000 with EnterpriseManager, but when I try in SQL 2005 through Management Studio my only"script mode" options are:- Script to file (which is one huge file with everything)- Script to Clipboard- Script to New Query WindowFYI, I get to this screen through Management Studio by right clickingon a database and selecting Tasks > Generate Scripts... > Next (doesn'tseem to matter what combo of objects I select to script or what otheroptions). I am using SQL Server 2005 Developer (which is Microsoft SQLServer Management Studio 9.00.1399.00).Any solution to this (i.e. via Management Studio, command line, etc.)would be greatly appreciated.Thanks.Ted
My customers are having problems to restore their own db.
They use SQL Server Management Studio and when they try to restore their db from a device and add the backup file an error message comes up stating that the user does not have permission to C:Program FilesMicrosoft SQL ServerMSSQLBackup.
How can I set a different backup location for each user?
HiWhat is the easiest option for Exporting ALL of my SQL Server tables into a CSV file (either separate CSV files for each table or one big file with all the table columns and data) ???I just want to Backup my SQL Server database like we backup MySQL database using phpMyAdmin. Unfortunately, my SQL hosting company does not allow backups for free.Thanks for help
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 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
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.
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?
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 usinga 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 logfile says this kind of things:·"Full PathName.MDF is not a primary database file." (This is one ofthe files repaired using the magic tool.·Error: 823, Severity: 24, State: 6·"I/O error (torn page) detected during read at offset0000000000000000 in file 'Full PathiName2.mdf'...

Thank you very much...:D
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.
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.

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
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?
I've written a custom script to delete backup files from location. But unable to modify now to count the number of files are deleted. How to modify the script...
/* Script to delete older than N days backup from a specific directory */
USE [db_admin] GO IF OBJECT_ID('usp_DeleteBackup', 'P') IS NOT NULL DROP PROC usp_DeleteBackup GO
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 scheduled automatic backup process but its only showing backup of the only one .sql file in the backup folder. Other created .sql files are not backed up. Why is it so?
I have a problem when i restore my .DAT_BAK file. I am getting error like "The backup set holds a backup of a database other than existing database. Restore Database is terminating abnormally".
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.
I want to do sql db backup.But how can I backup db to split backup files? The reason I want to split the backup file is becasue single file size is too big and I want to write to dvd.
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?
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?
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
I am going to move to a different host. Can I get back up files of my SQLServer database (from the host) and use those to set up on the new host? Andif so, is that what I should be asking for - backup files? Someone told methere should be 2 files.Thanks
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
I need to know how big SQL Server 7 backup files are in comparison to the database size. For example if I have a database that is 300 Mb and I do a complete backup to disk with SQL Server 7 will the backup file be about 300 Mb?
I hv worked in 6.5. There we take backup through the command 'Dump Database'(e.g---> "Dump database master to masdump WITH INIT." ). As for as I know, in 7.0 we are taking backup using the command "Backup Database". Is it possible to use "Dump Database" command in 7.0.
Hello everybody. I have SQL2000 sp3 standard with 50 db's
All db set for full recovery and autoshrink Backup done with Tivoli
full backup once a week log backup done every 12 hrs
Problem .. shrinking logs
every 20 min I run job DBCC SHRINKFILE (My_db_logFile) for every db
70% of the time I am getting message similar to ------------- Cannot shrink log file 2 (Wholesale_Log) because all logical log files are in use. -------------- 1. I checked with sp_who2 The is no activity on db 'Wholesale_Log' or any other db returning "Cannot shrink..."
Why i getting "Cannot shrink ..." ?
even if job runs right after backup of the log files ,I still have messages.
i want to delete the backup files older than 15 days. how can i do this? Actually i backup the db and log using the TSQL, and the backup files are in d:ackup folder. I tried sqlmaint,xp_sqlmaint but its not running .
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? thanks des
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.
Looking at the documentation, it would suggest that as well as data files, when a backup file's created it will also be zeroed out unless the service a/c's been given Perform Volume Maintenance.
We take our backups to dedicated backup servers, meaning backup performance should improve significantly if instant file initialization's given to the Service account logins for the source boxes if I'm right.
I have sent a mssql backup file in .bak format to my host admin and asked them restore it. but they told me there are 3 files with 3 different dates in that backup what does it mean? should I ask them to restore all of them or just the last one? Thanks very much in addvance (context: MS SQL 2005 express)
