Database Backup
Mar 31, 2000
In the Microsoft System Administration for Microsoft SQL Server 7.0 course notes it states, on page 170 (SQL Server Backup), 'Backs up the original database files and records their locations. The backup contains : Schema and file structure, Data, Portions of the transaction logs. The portion of the transaction that is backed up contains DATABASE ACTIVITIES SINCE THE START OF THE BACKUP PROCESS ....'.
In the Microsoft SQL Server 7.0 DBA Survival Guide it states in Chapter 10 Page 259 'When a database BACKUP DATABASE command is issued, SQL Server writes all completed transactions to disk and then begins to copy the database. ANY INCOMPLETE TRANSACTIONS OR TRANSACTIONS THAT OCCUR AFTER THE DATABASE BACKUP PROCESS IS STARTED ARE NOT BACKED UP.'
The first paragraph implies the database is correct to the end of backup and no additional transaction_log backup is required, the second that it is correct to the start of the backup and that an additional transaction_log backup needs to be done.
My question is which is correct?

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 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 take a full backup in the early morning and hourly transaction log back during the working hours for one database in the production server. The application team made certain changes to the design of the said database in their development server. The backup from the development server was restored to the production server during working hours. After the restoration should we take a full backup before next transactional logbackup? Would the transactional log backup with out a full backup after the restoration of a database be valid?

I have a database that is just over 1.5GB and the Full backup that is 13GB not sure how this is since we have compression on for full backups and my other full backups are much smaller than there respective databases...Now my full backup is taken every Sunday night and the differentials are taken every 6 hours after the full backup. Now I have been thrown into this DBA role with little to no experience just what I have picked up and read. So my understanding of backups are limited but what I think I understand is that we take a full backup and the differential only captures what changes in the database so my question is why is my database 1.5GB but my differential is 15.4GB? I have others database that are on the same instance and don't seem to have this problem. I also just noticed that we do not rebuild the index before a full backup like we do on other instances...

I should restore a SQL Server 2005 Database from backup. The backup contains three files, named user.bak0, user.bak1 and user.bak2.
How is the syntax of the restore filelistonly and the restore database ... ?
I usualy write
restore filelistonly from disk = 'path and filenam.bak'
restore database. zy
from disk = 'path and filename.bak'
with replace,
move.....
move....
This works but I cannot use it with a splitted backup file. The files are much too big to put together to one file.
Thanks in advance for any help.

Hi,
I have a MS SQL Server 2005 Enterprise Edition 9.0.2153 which manages my BizTalk Server 2006 Databases. The BizTalk server installer automatically creates a job named Backup BizTalk Server (BizTalkMgmtDb) which should back up the databases and transaction protocolls.
The SQL Server Agent runs under domain-administrator account which has full access to my backup directory D:ackups.
The job executes the following steps:
Step 1: BackupFull:
Command:
exec [dbo].[sp_BackupAllFull_Schedule] 'd' /* Frequency */, 'BTS' /* Name */, 'D:Backups' /* location of backup files */
Step 2: MarkAndBackupLog
Command:
exec [dbo].[sp_MarkAll] 'BTS' /* Log mark name */, 'D:Backups' /* location of backup files */
My challenges are:
1. The job doesn't back up my databases(D:Backups is empty after executing the job)
2. I get every time the following error in error protocol of the job:
BACKUP LOG cannot be performed because there is no current database backup. [SQLSTATE 42000] (Fehler 4214) BACKUP LOG is terminating abnormally. [SQLSTATE 42000] (Fehler 3013).
I have already switched the Databases from full to simple recovery mode and vica versa, it didn't help. Also, the above stored procedures doesn't include neither the TRUNCATE nor the LOG parameters for the logfiles so I wasn't able to solve this issue by adjusting these flags.
Any help would be appreciated.
Thanks in advance,
Greg

I am using sql server 2000 and windows server 2003 standard edition:
My database backup job is failing due to lack of disk space. I am taking the backup onto E drive and the
available free space on E drive is 6.85 GB and there are no other drives I can use for the database backups.
The size of mdf file is 21 GB and that of ldf file is 4.2 GB.
The transaction log back up job of that db ran fine.
This database recovery model is Full and
Auto shrink is not checked.
There is one primary filegroup for the database.
In this situation, I am thinking of the following option:
1. Backup the db and log files onto another network shared drive.
If I want to still use the same server E drive to backup the db and log files instead of using another network shared drives.
how can I do that.
Please let me know the best way of handling this issue.
Any help is greatly appreciated. Thanks!

I neglected to backup the transaction log as part of the process of backing up the database. Now i only have the backup file for the database and no transaction log backup. When i try to do a restore on the database, i get the error on a "tail log missing" message (which i'm assuming is that it's looking for the t-log backup?).
Is it possible to restore or even restore to a new database? I'm only looking to retreive data from 2 tables within the backup file.
Thanks!
SQL Server 2005 on Windows 2003 Server x64.

We replicate a SQL2000 database (DataBaseA) to a SQL2000 database (DataBaseB) by using the Restore function and hasn't change its logical name but only the physical data path and file name. It is running fine for a year. We use the same way to migrate the DataBaseB to a new SQL2005 server with the Restore function and the daily operation is running perfect. However, when we do the Backup of DatabaseB in the SQL2005, it just prompt the error message
System.Data.SqlClient.SqlError: The backup of full-text catalog 'DataBaseA' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online. Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)
Please note we left the DataBaseA in the old SQL2000 server.
Please help on how we can delete the Full-text catalog from DatabaseB so we can do a backup
Many Thanks

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.
Msg 3013, Level 16, State 1, Line 1

Anybody figure a way around this:
In a development server you take a backup and you want to move the entire database to a production server. The production server does not contain the database, users, or logins in master.
When you restore the backup to production in 7.0, the users get moved to DBO because the logins do not exist and then you cannot delete them.
We are having to drop the users from the database on development, back up the database and restore it to production, then recreate the users on production.
This is bogus and did not happen in 6.5 because of the aliases.
Anybody come up with a better way?

I am fairly new to VS 2005 and SQL Server CE. I have developed a Desktop Windows application using VB 2005 and the SQL Compact Edition Database. This application will sell to users via web download.
When they download a service patch, or updated version, I wish for them to retain the data in their present database. In other words, fill the new database with the old data. The new table structures will remain intact except for added columns at the end.
Question is how to save the old data and update the new database with it. Is there an easy way to do this, or do I need to write a module to save a database copy, and update the new database with content at install time?

I have a Subscriber database updated using transactional
replication and want to create a copy for development & testing. The Distribution database is running on the
same 2005 instance as the Subscriber and the Publication database on another
server running SQL Server 2005.
If I use a TSQL script to run the restore, the database is
restored to a usable state but I get the following messages:
Msg 15247, Level 16, State 1, Procedure
sp_MSrepl_check_job_access, Line 112
User does not have permission to perform this action.
The replication agent job [job name] was not removed because
it has a non-standard name; manually remove the job when it is no longer in use.
(I€™ve removed the job name from the message)
RESTORE DATABASE successfully processed 46219 pages in
935.413 seconds (0.404 MB/sec).
It looks like an attempt is being made to restore
replication information too. I note that
the RESTORE statement has a KEEP_REPLICATION options which implies (I would have
thought) that by default the replication information is not be restored.
Incidentally, before implementing replication, backing up
the live database and restoring the backup to a new database took < 7
minutes but running the same process with a Subscriber database backup takes
about 15 minutes.
I€™d be interested to know if anyone has any idea what I€™m
overlooking or doing wrong.
ThanksTim

Is there any way of doing it?

Due to a network time skew some time ago, all of the databases on an SQL system now have the following information stamped on them..
Within Enterprise Manager (SQL 2000), The "Last Database Backup" timestamp for each database is showing the year 2025.
Our backup system runs incrementally daily and a weekly full. Unfortunately, the timestamp does not seem to be updating as the year is as I guess in the future.
Can anyone advise of a procedure so as I can wipe this time skew date from each of the databases?
Many thanks folks!

I am building a web site ( C# ) that would be selling mostly downloadable digital products. My questions regarding this Database Backup are:
1) I have no idea about what frequency of backups is appropriate. Should they be done in a hourly basis ? daily basis ? weekly basis ?
2) Can they be done without deactivating the web site ? If so, how ?
3) How it can be done ( programmatically or by some settings in the database ) ?

I am ultimately trying to backup my database from a deployed site to my PC's disk, because tools such as MyLittleBackup, which is provided by my hosting company, is done under http and not https.
But initally I am trying to get a backup working on my local ASP.Net development server. I am getting the following error message;
"Could not locate entry in sysdatabases for database 'MyDatabase'. No entry found with that name. Make sure that the name is entered correctly. BACKUP DATABASE is terminating abnormally."
My stored procedure is;
ALTER PROCEDURE dbo.DBBK1
AS
BEGIN
BACKUP DATABASE MyDatabase
TO DISK = 'C:Documents and SettingsBBBNMy DocumentsMyDatabase.bak''
WITH FORMAT;
END
RETURN
My Stored Procedure is called by the following script:
cnn1.ConnectionString = "Data Source=.sqlexpress;" & "Integrated Security=SSPI;" & "User Instance=True;" & "AttachDBFileName=" & My.Computer.FileSystem.CombinePath( _ Server.MapPath("/MyWebSite/App_Data"), "MyDatabase.mdf")
cmd3.Connection = cnn1 cmd3.CommandText = "DBBK1" cmd3.CommandType = Data.CommandType.StoredProcedure cnn1.Open() Try cmd3.ExecuteNonQuery() Catch ex As Exception Message1.Text = (ex.Message) Finally cnn1.Close() End Try
I'm not sure what I need to consider to progress this. Any help would be appreciated.

I've built a website on a virtual hosting account. I've created a couple of accounts but i've create many tables in my database. I'm moving to a new hosting provider. I've backuped and copied my asp.net files and everything on my webserver. But i cannot copy my data. If i want to backup my data with sql management studio express, it refuses. I've tried Enterprise manager, which cannot connect to my mssql 2005. How can i solve this. Their must be a way. I'm a rookie by the way.

Here is my problem.
I have a couple DTS that are schedule to run each 10 minutes.
We have a Database Backup that is running each 4 hours.
My problem is that it's happening that the DTS and the backup are running at the same time and this is causing some problem because the DTS can not insert data into a database when a backup is running for this database.
I was thinking to add a step to my DTS to verify if the Database is being Backuped and i don't want to validate with the scheduled job of the backup because sometime we starting it manually. Is there another way to verify if the database is being backuped???
Thank
Martin

I recently installed SQL 7.0 SP1 and SMS 2.0 SP1 on the same machine. I'm looking into a backup solution for the SQL Database. In the past I've used ArcServeIT and their Oracle Agent to backup an Oracle 8 database. The database restores worked well. Does anyone have any suggestions for an SQL solution? I'm also in the process of researching a complete backup package for our NT servers so I'm open to all suggestions.

I have created a scheduled job to backup my application database as well as the MSDB and Master database to one output file. I have done this to be able to completely recover my SQL server installation for any particular day all in one file.
When I want to go back and restore the database, using enterprise manager, It won't allow me to restore the application database, I get a message saying "The backup set holds a backup of a database other than the existing 'application database."
I have tried all options I can think of (database, filegroups or files, from device) with no success.
Anybody have any ideas? Please don't tell me to "separate them" or to "tell Microsoft" as these types of answers don't do me any good.
Thank you.
Thanks,
Bill.
