DB Engine :: Backing Up MDF And LDF
Jul 22, 2015
I'm having an ongoing fallout with the Operations team where I work about database backup strategy. Â They use vSphere (VM ware) to backup all the disks on the servers and included in this are the SQL backups. Â Now I don't really trust this because whenever I ask for a restore, which is very infrequently, they give me an mdf/ldf pair. Â To my mind this shows they are just backing up files and although these files can be re-attached this is not safe, as they were open when the backup was taken. Â Â What I would like to do is use native (or RedGate) backup to create a full backup and have the vSphere pick up the .BAK files.Â

We're trying to create a .bak file to send it to our site's admin to restore it on the
server:
1. When I try to do that get this error:http://www.radiorient.net/errors/export_sql.gif
Why is that? and how can I fix it?
2. Should we add both files of the db (.MDF, and .LDF) or only the .MDF file?
Can please someone help me with this, Thanx.

I just got SQL 7.0 and was curious how other environments run their backup. I know ArcServe has a product that backs up open SQL databases and not sure how reliable this product was. Any thoughts would be appreciated .. thanks.

HiI'm hoping that some could point me in the right direction for "bestpractice" in:1) securely backing up a complete sql7 and 2000 server containing manydatabases.2) backing up an individual database3) Securing the transaction on the hour as a mile stone to return to in theevent of error or system failure.ThanksMark

Hey, please forgive me if my infomation source was incorrect. But a friend of mine mentioned to me he had hurd of a program, or code that will make an "install script" of your database. Basically it`ll back up all the tables on your server and if the worst case senario happens then you can run the file like an install script. Is this true? It sounds invalueable! If it isnt true, can someone tell me if it is possible to use code to create a "install script" of your own database? I am using "Microsoft SQL Server".Thanks in advance John

Scenario:
I have August22 full backup and August22 and August23 transactions log backups . I want to get the August23 and August23 full backup. So I performed a restore backup with August22 full backup and all the August22 trn backups. Then I backed up giving it August23 name and repeated the process with the August23 trn backups. But, I get an error saying that the transactions haven't been rolled foward far enough. But, I am not missing any trns! I will really be grateful if anyone would help.
thanks.

When backing up a database in MS SQL 7.0, there is a window that appears in the destination section of the backup window. In this window is where the filename appears that the backup will proceed to and to the right of this window are "add", "remove" and "contents" buttons.
If there are multiple names in this window, will the entire backup go to both files or does it split the backup between the two filenames.

TO backup a DTS package, does backing up MSDB take care of this or do the files need to be individually backed up?

I use SQL Server 2000 and I create scripts on a daily basis to do the following
1. Rename a table
2. Create table with original name and add new field
3. Copy data from renamed table to new table
4. Build indexes
-----------------------------------------
execute sp_rename ORIGINAL, OLD
GO
CREATE TABLE [dbo].[ORIGINAL] (
[A] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
[B] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
[C] [int] NOT NULL ,
[Notes] [text] COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
INSERT INTO ORIGINAL (A, B, NOTES)
SELECT A, B, NOTES
FROM OLD
CREATE CLUSTERED INDEX [ORIGINAL_A_B] ON [dbo].[ORIGINAL]([A], [B] DESC ) WITH FILLFACTOR = 90 ON [PRIMARY]
GO
-----------------------------------------
ON A TABLE WITH 100,000 RECORDS THIS KIND OF SCRIPT TAKES A LONG TIME TO DO THE INSERT/SELECT PART
I WOULD USE ALTER/ADD TO UPDATE THE TABLES, BUT MY SUPERIOR INSISTS THAT NOT HAVING TEXT FIELDS AS THE LAST FIELD IN THE TABLE WILL CAUSE QUERKY PROBLEMS WITH HIS SQL STATEMENTS
DOES ANYONE HAVE ANY KNOWLEDGE THAT THIS COULD BE TRUE?
IF SO,
DOES ANYONE HAVE ANY IDEAS FOR DOING THIS SAME PROCESS TO ADD A NEW FIELD (C) BEFORE THE FINAL FIELD (NOTES - TEXT FIELD), AND BACKUP THE TABLE BUT WITHOUT IT TAKING SUCH A LONG TIME ON THE INSERT/SELECT PART?
Forgive me if I'm asking a lot, but I'm lost and these scripts take way too long for what seems like such a simple task.
Thanks,
Mitch

Hi,
I've recently created a maintenance plan, which backs up my database and transaction log. However I also have a Veritas (Backup Exec for Windows Servers) tape backup which runs at night and backs up my files. It is setup to backup the whole of my MSSQL DATA and BACKUP folders.
Today I went to do a test restore, and found that the tape backup contained nothing in the MSSQL DATA folder, but everything that was in the BACKUP folder. Is this because everything in the DATA folder is in an open state? On checking back, the tape backup has never held anything in the DATA folder. Should I be worried by this, or is it what you would expect, and is the SQL backup sufficient?
Thanks for any advice
Colin

Hi, not sure I have should ask this in here or in the VS forums - but here goes anyway!
My vb app is written using VS2005 with an SQL database. I'm now distributing this to users to use with SQL Express.
It's hard enough explaining to them how to attach the database without going into the backup routines etc!
So what I'd like to do is to have a "backup" button in my app, that backsup the database, trancates the log files & then shrinks the files.
Is this possible?

HI All,
I am currently in a situation where I have been fed to the wolves to say the least.
My task is to take the current SQL server 05 we have running on a drive array partioned as C & D and rebuild it.
I need to have the current database backed up, as well as the unique permissions that are currently present on the database.
I then have to remove the hard drives from the RAID array, and replace them with Brand new ones. The OS will then have to be reinstalled, followed by the nessary updates and finally with SQL server.
I then have to import the database back to the new server build w/ the data and the permissions all intact.
Anyone have any idea of how I can go about doing this?
Steve

Hi, I am in a production database server. Data has been added and deleted via the web. So there is alot of traffice in and out of the database. How can I make a backup plan to make sure I am not lossing any input or deleted data . I am familiar with backing up a database in regular intervals, but I amnot sure if this is the best way in this senario.
How can I take advantage of the transaction log in restoring the database.
Thanks

hi, I have total 45 GB of data in the following servers ( 40 GB in sql server 6.5, 5GB in ftp server). both servers are in one machine(server). I want to make sure that I am doing the right thing for backup. The machine is not connected to a Lan. What is the best way to insure that my data are backed up safely?
what I am thinking of doing is to back up the database to using sql tools in the menu bar, that will backup the data to the same machine in this directory:
c:mssqlackupDBname.DAT
I will do this for all database in the sql server. Am I save to do this... I am wondering what IF the machine in which both severs are in crashed. My backup effort will be lost too. right. so what is the best way to protect my data. Do I need to buy a tape backup so I can do what I am doing Plus back up the c:mssqlackupDBname.DAT to the tape backup... I would really appreciate any suggestion in choosing any media (software/ hardware)to back up my data.
Thanks

Since sql server EM doesn`t allow you to restore a stored proc. from a dump tape, I`ve been testing bcp and the sp_helptext procedure to dump our stored procs. out to a file to provide a backup.
Small stored procs dump just fine but larger ones cause an occasional "wrap around" in the output file. The output file looks something like this:
CREATE PROCEDURE xyz AS
declare @table sysname
decla
re @count integer
So when I copy/paste from the output file to a new stored proc in EM and try to save it, I get a syntax error.
Does anyone know how to dump a stored proc to a file so that it doesn`t wrap?
I`d like to use bcp or some utility to backup all stored procs. to a flat file on a nightly basis.
Thanks RIchard

Hi
Would it be better to take backups of my production server using arcserver SQL agent (or seagates backup utility ) rather than use SQL enterprise backup ? What are the disadvantages.
I need to desing a backup procedure of my production database which is being updated continously.
Also would I be able to set checkpoints while backing up transactions logs so that I could take backups upto a certain session.
Are there any pitfalls in using third party utilities for backing up sql server 6.5 databases.
Please advice.

Guys,
Should the transaction log of the system databases be backed up and if so, how often should this be done, generally?
Currently, we are backing up the system databases daily. The transaction log of the system databases, however, is not backed up.
Recently, I was wondering what exactly could happen, which would imply that we need to back up the transaction log of the system databases.
As far as I understand, 'msdb' contains things like jobs, dts. As such, if no jobs/dts are added in the middle of the day, there is no need to back up the trans log of this db - there could even be no reason, in such case, to back this db up at all!
'master' db would change if we add/modify objects/properties and so on ... so unless many changes are made, no need for backing up its trans log.
Having said that, could anyone enlighten me as to whether it is necessary to back up the transaction log of the system dbs and/or what it depends on and/or when it is suggested to do so?
Thanks you
