Best Backup/restore (OLTP/OLAP) Practices In 2005
Aug 14, 2007
We have a live OLTP database for which we create full backups every week and differential backups every day. Recently we added an OLAP database, which we need to update daily with changes from the live database.
This is the process we are planning to use.
1. Restore last full OLTP backup.
2. Apply the last differential OLTP backup.
At this point we should have a replica of the live OLTP database.
3. Update OLAP database based on the OLTP replica database.
4. Delete the OLTP replica database.
Two questions.
1. If different from the process above, how is this OLTP-to-OLAP transformation typically done in the industry?
2. What is the best way to implement this process with SQL Server 2005?
Thanks.

Hello,Can I import an OLTP (Reltional DB) as a Data Source into SQL ServerAnalysis Services 2005 and then use the Cube Wizard and the new DataSource View feature to create the OLAP model ?Or do I have to first design an OLAP Data Warehouse with a Star Schemaand then import this DW as a Data Source into my Analysis ServicesProject.With SQL Server 2000 , OLAP would be the way to go..but with SQLServer 2005 , it seems as though the wizard and data source viewfeatures do half the work for you.I have an OLTP DB and am not sure which route I should take ! Anysuggestions / input would be much appreciated.Thanks in Advance...RegardsRusszee

Hello All,
Our OLAP environment involves an ETL/Data Warehouse/Data Mart server and a cube publisher server.
We would like to learn how to automate the Archival/Restore of OLAP databases. We are currently doing
it manually though OLAP Manager. Any help would be appreciated. Thanks. James.

Hello,
In the process of migrating a logshipped database (in non recovery mode) from SQL2000 SP4 to SQL2005 SP2, I got the following error (sorry for the french translation!):
---
Conversion de la base de données 'AdStatistiques' de la version 539 à la version actuelle 611.

Msg 3013, Niveau 16, État 1, Ligne 1

Of course, the restore operation performs well when the destination is SQL2000. I suspect the integrity checker of SQL2005 to be less permissive, hence I run a checkdb on the original DB, which raise several errors, which are quite difficult for me to analyse:

Is there any easy option you can see to operate the transfer, since the backups I have from the DB already contain the data corruption?
Thanks a lot for any hint you could provide,

Does anyone know if this works to where the data is viewable/usable?
I have an application that takes datasets out of the SQL database. We decommisioned our old SQL 2000 SP4 machine and brought in a SQL 2005 Server. What we did was backed up the old database and then restored it on the new Server.
Now the application does not see the old datasets but will collect new ones that are viewable. We can import older datasets but we have nearly 27 GB of data, which our DBA can see the old tables in Enterprise Manager but our applciation can't see it.
I'm thinking it might be a schema issue or the way that 2005 translate the odler 2000 SP4 database. Does anyone know, or have they run a back up on a older 2000 Server and then restored it to a 2005?
Thank you.

Hello,
SQL Server 2005 TR with IU/QUS - Restore from a backup
Im trying to set-up the above using sp1. It all works fine until the final step, creating a subscription through sp_addarticle and Im getting the following error:
Msg 8152, Level 16, State 10, Procedure sp_MSget_synctran_commands, Line 198
String or binary data would be truncated.
This worked fine on my laptop with a small table with a couple of columns.Now Ive looked at this error and its like
select * from #art_commands
The table only has 49 columns in it, so its not huge.
What are my options for solving/getting around this problem:
1. Try and fix sp_MSget_synctran_commands, from memory, #art_commands has a nvarchar(max) column and Im wondering if this is related. must admit, havent really looked solidly at this sp yet.
2. SP2 doesnt look like it fixes this problem.
3. Create a bespoke method to replicate.
4. anymore for anymore?
It will be impossible to synchronize the databases so this restore from backup was my only option. Im a bit stuck now, can anyone help?
many thanks,
John P

Hi, Our Sharepoint of TFS was down a couple of days ago. By luck, we had fully backed up SQL database. Now, the problem is, I uninstalled everything and tried to move TFS to a new server machine on the domain. I installed freshly everything and tried to restore all the databases (with tables also). Now the problems are these:
1 - Since there are lots of different backup-restore procedures telling on the Internet from some forums and this forum also: What should i do basically to make the configuration of Sharepoint and Reporting Services to make them work correctly?
2 - Secondly, even if i fail in the problem above, I, at least, want to save the source control files and sharepoint files. Where can I find them and how can I take them back to my new TFS installation?
3 - If these problems exist and Suppose on a new project on the new installation, i create new WI's, documents (with new Version Control information), and new SPS configuration. And on a new release,the problems are resolved. Is there some way that I can merge the former Backup with the new installation's database?

We are preparing to stand up a server with an HP tape library backup system using Data Protector software.
Our intention is to copy backup files from each of our db servers to the file system of the server with the tape library. There will be two tape rotation schemes where there will be a daily offsite tape and one with a monthly offsite rotation for less critical applications. Our systems group isn't happy about that configuration but are willing to implement what we want.
My questions are:
Is there any one out there using one of these and if so can you give me a 10,000 foot view of your process?
Addtionally, is this the best way to utilize this resource?
Any serious suggestions and comments are greatly welcomed and appreciated.

Hi,
I'm currently working on a project which uses a SQL Express 2005 database. I want to be able to setup SQL Express from my C# program so that it can perform backups to a specified path location at the requested interval itself. This would free up my program from having to manage the backups. Just wanted to know if this is possible?
Also, when the current database becomes corrupt will SQL Express perform the restore for the user automatically, instead of them having to manually request a restore? I realize that it might not be able to handle the restores in the same way as backups, but I figured I'd at least ask.
Thanks,
KingyNL

Hi All,
I'm about to embark on creating a maintenance plan to back up all databases on one of our SQL 2005 servers. I am looking for some advice on best practices for doing this.
I have it in my mind that i want to be taking a full database backup once a week, with differential backups on a daily basis and transactional backups performed every 2 to 4 hours.
Do i need to create three maintenance plans for this, i.e. 1 for full, 1 for differential, and 1 for transactional?
If i want to only keep the backups from the last week, is this done by setting up a maintenance cleanup task in the full backup plan to clear all bak files that are a week old?
If so i'll also probably require one to remove the trn files also.
When using the backup command from the context menu in SSMS there is an option to name the backup set. How does this work when using maintenance plans as i haven't been able to find this option whilst trying out some of the features?
I'm sure to have more questions on this subject, but any help on the above queries would be most appreciated.
TIA,
Grant

I'm trying to see the differences between Backup/Restore and Attach/Detach. I backup and detach a database from SQL Server 2000 SP3 and then attach and restore it to SQL Server 2005 SP1.
The differences I noticed are:
1. The restored database has a much larger initial size (database size is same) for data and log.
2. The attached database has a last backup date
3. If the backup is restored over a database, the restored database is showing owned by the database owner of the database restored over but syslogins and sysusers do not match.
I don't understand why #1 happens.
Are there any other differences between Backup/Restore and Attach/Detach?
Thanks,
Peter

I was once told that I was not to use the GUI to setup a maintenance plan. What the person said was that I needed to setup a different plan to do each tab of the GUI instead of going through the tabs and making sure the times do not overlap.
Has anyone ever heard of this or is this an old wise tale told by only one person?
I am using version 8 of SQL on XP machines with 8 connections to that database and need to back up the database, clean it up and everything the GUI has, so teach me the correct ways and tell me why, thanks!

We had one of the major issues where one of the table on a heavily used OLTP database seems to have updated the records which were not expected.
Scenario:
We got around more than 12K contracts updated to status expired even though the expiry date is not set to be so:
for E.G : Below table has a column contract status which overnight seems to have updated the values to expired.
Even though the start and expiry date does not follow the logic for above.
We had the above working for past 3 years via a SP scheduled via SQL agent Job which Expire active contracts whose expiration date is less than today's 12:00AM.There has been no change in SP.
How can i track how it happened and what caused it?

I am looking for a SQL Backup/Restore tools which can restore multiple environments. Here is high level requirements.
1. We have 4 DBs, range from 1 TB - 1.5 TB Each Database. When we restore to QA, DEV, or Staging, we usually restore 4 of them.
2. I am looking for the speed to complete restoring between 1 - 2 hours for 4 DBs.
I am evaluating the Dephix Software but the setup is very complex and its given us a lot of issues with Windows Authentions, and failure in the middle of the backup. I used Guess Software many years ago but can't find it on the web site any more. Speed is very important for us mean complete restoring as fast as possible. We are on SQL 2012 and SQL 2008 R2.We are currently using NETAPP Technology and I have Redgate Backup Tool but I am mainly looking for fast Restore Process.

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.

I was running Small Business Server 2003 with MS SQL Server 2000. I put backups of all my SQL Server 2000 databases on hard disk d: and the operating system and applications on c:/. I then reformatted c:/ (but left d:/ intact) and installed Windows XP Home. Then I installed MS SQL Server 2005 Developer's Edition.
I would like to now restore the backups of the SQL Server 2000 databases (still intact on drive d:/) to SQL Server 2005, but I get a variety of error messages.
I suspect that I am going about this the wrong way. I have done several hours of research in the documentation without success. I cannot attach the SQL Server 2000 database to SQL Server 2005 because it is a backup, not a database. I cannot migrate the databases as part of the installation of SQL Server 2005 because (a) they are back-ups, and (b) I don't have SQL Server 2000 installed when I install SQL Server 2005.
Is there a solution?
TIA
