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 1
MB)???
The problem I've met is that the DB backup file is too large, over 4
GB, and even Winzip can't compress it (after compressing, around 80 %
of compression rate is possible)
Thanks!

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

Hi,
Using SQL Server 2005, we have a 2.8Gb database under the Simple recovery model. The database contains ~50M rows and each night ~60k rows are loaded(appended) to the database by a SSIS task.
We configured a Maintenance Plan which is executed once a week to perform a full backup of the database. The resulting backup file is ~2.8Gb, as expected.
We also configured another Maintenance Plan which is executed every day, a few hours after the SSIS task is executed, to perform a differential backup. To our surprise, the resulting backup file is about the same size as the full backup, ~2.8Gb when it should only be a few MB (only 60k rows are added to the database)
When we launch the "Restore Database" wizzard we clearly see the different backup set, Full and Differential but they all have about the same size (same for the physical backup file on disk).
Is there anything we are missing, why are the differential backup that big?
Thanks for any advice.
Hey guys,
I'm wondering how most people manage very very large backups. What is the best approach to breaking up the backup files if you're restricted to a drive size (450gig in my case). I unix, you can pipe the backup to gzip and split, I'm not sure how the same thing could be accomplished in windows.
Thanks,

View 4 Replies View RelatedHi all:I restored one backup database (7.9 GB mdf) on two diffrent servers. Ishrunk them by clicking "Move pages to beginning of file beforeshrinking".After shrinking, one mdf file is 6.7 GB, and the other is 4.2GB. Ishunk again and again:1. the 6.7GB become 5.9GB, 5.2GB, 4.7GB and 4.2Gb (four times)2. the 4.2Gb become 4.0GB (just one more time)It is wired, I am wondering the mdf will be smaller and smaller if Icontinue to shrink them? What is the reason?ThanksWJ

Before my arrival at my current employer, our consultantsphysically set up our MSSQL 7 server as follows:drive c: contains the mssql enginedrive d: contains the transaction logdrive e: contains the data filesNo filegroups were set up and the data files consist of only 1 largephysical file. Currently, our data file is >10GB. When I was trained onthe physical aspects of sqlserver, I was told to never create physical files[color=blue]> 2048MB each. If I did, I could expect inefficient physical storage of[/color]data and slower performance (due to the OS).Our server has 2 RAID-5 arrays. Drive c: and e: are located on the firstarray and drive d: on the second. We're running Windows 4.0 NT Server SP6with NTFS.Can someone comment on the use of 1 single large data file vs. more smallerdata files?

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,

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.

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?
Thanks
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'...

The physical file name 'Full PathName2.mdf'may be incorrect.When i try to execute the command "DBCC CHECKDB ('Database_Name') WITHPHYSICAL_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
View 2 Replies View RelatedDatabase File Placement Layout? We are planning to implement a new SQL Server 2014 OLTP Database with a 1 TB Data file and 1 TB Log File. I am looking at the possible layout of the database files and trying to determine the best possible configuration. My knowledge/research tells me that items which need separate storage due to constant simultaneous access are:
Data files – should go on the fastest reading storage.
Log files – should go on the fastest writing storage.
TempDb – involves a lot of writing at the same time the data files are being read.
Indexes - (including full text indexes) - involves a lot of writing at the same time the data files are being read.
Also, are there any benefit to having multiple OLTP Database Log files? Because SQL Server writes to the log file sequentially, I do not see any advantages to having multiple database log files. In a SQL Server 2012 Class I took last summer, under “Determining File Placement and Number of Files”, it states “Use a single log file in most situations as log files are written sequentially.”
Hi all,
I found a database file and a log file over 2G on mssql 2000 server. Actually, they only need around 200M. I try to backup, truncate the database in order make the size smaller. But the size cannot be smaller. How can I do it?

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?
I have RAID 5 with 1 logical drive with 2 partitions with SQL Server 2000 running on SERVER.
what best model for data storage and backup would some experienced one suggest:
basically I want to put Master, Database files and T-Log files away from each other.
-- Data files
-- Log files
-- Master database.
Thanks,
Fahim.
How to move the database backup files (.bak) from one server to another server using ‘XP_CMDSHELL’

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.

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

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 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.
Can i anyone please help me out?
Thanks in Advance,

Hi everyone,
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.
any idea or scripts?
cheers
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
We are using sql server 2008 r2 standard with sp2. I have a 12 GB database in production server, log file was set to 150MB with increment of 10 percent, in last 4 years database size has gone from 2gb to 12 gb. I ran following command
DBCC LOGINFO
And found I have 150 plus rows(which means 150 plus virtual log files)
I increased the size of log file to 25 percent of data file which comes to be approx 3gb and also set auto growth to 20 percent ...
Additional info: we have a log shipping environment in production, i am taking log backups every 15 mins.. still number of virtual log files is same , why is that , how to bring them between number of 25-50 as thats the recommended.
Hi!
I have a bit of a problem with importing (DTS Package) from a text file into an existing DB.
The file has no column names and every file only contain 1 row. This row varies in number of columns.
My first thought was to create a table with the maximum numbers oc columns that can appear in the text file.
An example:
Table with 4 columns; Col001, Col002, Col003 and Col004
The first text file:
123,Peter,Ocean Street,NY
The second text file:
356,John,Park Avenue
My aim is that the second file should append to the table, leaving Col004 as (NULL)
Any ideas how to get this to work?

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 didnt backup both of the files. I dont 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
