SQL 2005 backup

Hi,
I'm using Small Business Server 2003.
I've installed SQL 2005 Database Server for ERP.
I need to take the backup of the both SMB 2003 and SQL Database.
If I take Full back from SMB 2003 will this also take backup of my SQL 2005. Or do I need to take SQL backup separately.
Sathish

If I take Full back from SMB 2003 will this also take backup of my SQL 2005.
Not the databases, they are permanent in access by SQL Server and therefore you can't perform file backups on them You have to use the backup Feature of SQL Server instead, see:

Restoration at sql 2005 from sql 2000 backup.

Hi experts,
Is it possible to restore a backup taken from sql 2000 database to sql 2005 database?
And how about attaching datafiles of sql2000 into sql 2005 server?
Thanks and Regards,
Amit Jana.

> Is it possible to restore a backup taken from sql 2000 database to sql 2005 database?
Yes its possible.
> And how about attaching datafiles of sql2000 into sql 2005 server?
Same method of attach/deattach.
But recommanded you first install 2000 instance restore database and do inplace sql 2005 upgrade.
Why you can't follow recommanded mothed ?

Performing backup of SQL via backup interface

Hello all,
First of all , let me tell you that i don't have much knowledge regarding SQL so, excuse me in advance for any stupid questions.
Here is my situation:
I have SQL 2005 Standolne server. On the server there are two interfaces(NICs) one is so called production(prod) and backup(bkp).
The PROD is for main communication and it's with assigned FQDN - XYZ. The other one is for backup traffic and it's with FQDN - XYZ-b. The IPs are , PROD - xxx.xxx.1.xxx, BKP - xxx.xxx.2.xxx
I'm using a HP Data Protector software , version 7.03, with latest patched installed on the backup software.
Unfortunately when i'm trying to create a backup(there are 3 ways for authentication - Integrated, Windows and SQL server) with the BKP interface i receive following error:
*RETVAL*8010
The user name which is used by the bkp software is added into the SQL server as admin, also it's with local admin from OS point of view.
So my question is , are there any way to perform backup via XYZ-B interface ?
Thank you in advance !!!

Hello,
Seems to be more a HP Data Protector issue, see

SQL 2005 SAP R/3 4.6C - DBSL error RC=99 on import of Basis 4.6C SP 39

Hi,
I have just built a R/3 4.6C system on SQL 2005 with 4.6D_EXT kernel. The build was done using R3load to export from the 4.6C/SQL 2000/32bit system and import to 4.6C/SQL 2005/64bit system. The source 4.6C system only had Basis support package 37 applied, and I am trying to apply Basis 4.6C 38-57 on the 4.6C/SQL 2005/64bit system (in preparation for an ECC6 upgrade) and I get the following error:

I have checked the collation setting in SQL 2005 and it is:
select serverproperty('collation')
SQL_Latin1_General_CP850_BIN2
There are 97000 odd entries in DOKIL, so I don't think that is the problem.
Would appreciate any assistance.
Kind regards,
Sheryl.

Hi ,
Instead of doing the build with export import, you can try to do the same with backup restore,,
But remember your sql2000 should be on bin2... then you can take backup and restore.
Since it is from 2000 to 2005 the restore would happen and it will work fine.
Try this and check out, since the error you have pasted is not clearly giving any picture...

Ravi.

SQL Upgrade 2000 to SQL 2005

We are upgrading to new server and installing SQL 2005. Using Crystal Server 10. Where can I find a step by step? Can I just backup Business Objects Database, install the app on the new server, restore the database to SQL 2005?
Thanks,
SS

Microsoft SQL 2005, Terminal Services and Tiger

We found a great application we need to use at work. Unfortunately, it runs only on Windows. We will need to run it on a Windows server, running SQL Server 2005, and Macs interacting with it using MS Terminal Server. At least that is what someone at Dell said. This ends up being a huge and complicated purchase for us.
All this is totally foreign to me. I set up our Mac network, using OSX Server 10.2, migrating up to 10.4. We have 16 computers on the network, and it runs reasonably well. I did not need months of training to set it up. There are many things I do not understand and features that I have zero idea about...but for email, web, ftp and application serving, it works well.
We have 13 Macs, 2 Windows boxes and one UNIX box on the network.
Has anyone used SQL 2005? Has anyone had to connect thru Terminal Services to a Windows Server?

Hi John!
Using Terminal Services on a Windows server is common in corporate environments and solves a lot of issues where Macs can't run Windows-only software.
Since the Windows server will be the only Windows machine on your network and you only need it for a specialized purpose, you can probably get by with purchasing Windows Small Business Server Premium, which comes with a SQL Server. You'll have to ask the vendor if this version will work with their product. See this link on Microsoft's website http://www.microsoft.com/windowsserver2003/sbs/default.mspx.
Many third party database applications will facilitate the setup of the datbase with the SQL server, but they won't support the SQL software and its security. I'd advise hiring a contractor to help with the installation and setting up a backup (preferably someone that can become familiar with your environment and provide ongoing support).
Hope this helps! bill

Can't restore SQL 2005 BAK to SQL 2008 R2 running on Server 2012

Hi there,
Preparing to switch from SQL 2005/Server 2003 to SQL 2008 R2 / Server 2012. Took a backup of the SQL database on 2005 (stored at a cloud backup provider nightly) and copied to the new machine. Unable to restore the .BAK file, with the error:
The media family on device <backup path> is incorrectly formed. SQL Server cannot process this media family.
RESTORE HEADERONLY is terminating abnormally. (Microsoft SQL Server, Error: 3241)
Tried it with two different backup files from two different nights, same error. I understand that this error can show up when restoring to a lower version of SQL, but that's not the case here.
Also, I know this can occur if the BAK file is corrupt, and I can't verify that yet, but two in a row failed. I'm hoping our cloud solution isn't part of the problem somehow.
BAK file is 15 Gb in size, so don't have the ability to attempt the restore on the 2005 production server. Just not enough room, and can't afford to cause performance issues on that box anyway.
Anyone know of any way to get a better handle on what's going on, or, even better, how to resolve it?
Thanks
Robin

SQL Express 2008 R2 and SQL 2005 Server SP1 in single Windows 2003 server

Hi,
I am using a Windows Server 2003 R2 Enterprise Ed SP2 OS with SQL 2005 SP1 intallled on it for our Nav 5 database.
As my backup software requires SQL Express 2008 R2 as default daabase, is it possible to install this in the same server with the SQL 2005 currently running on it? Would there be any impact on the existing SQL 2005 and the application and the Navision database
on it?
Appreciate your help.

There is no issue with installing multiple versions of SQL Server on a machine.I have SS 2005 ,2008 R2 and 2012 all on same machine and they work just fine. You can install all version instances side by side and all will work independently from
each other.
Now issue which might cause problem your SQL Server 2005 is SP1 which is a Blunder IMO. Please ASAP patch it to SP4 because you are running very old version of 2005 which is unsupported by Microsoft and also SP4 includes MANY fixes for SQLServer
2005. Applying SP4 will fix many issues and will bring you under Microsoft support.

Crystal 8.5 connection with Sql 2005

Post Author: sgtpep
CA Forum: Semantic Layer and Data Connectivity
Hello all,I'm not sure this is the right forum group to post in, but here it goes:I have a problem when trying to print my crystal 8.5 reports through a sql 2005 native client.Some of them work just fine, but i get this error: "print job failed cannot open sql server" for others.I've been doing a little research, but i can't seem to find a definitive answer on this topic: Can/Does crystal 8.5 work with sql 2005 databases.I did find something about upgrading my drivers, but i'm not sure where to find them and what i should be looking for.Thanks in advance for your help,Eric

I see - the field notice does mention ICM 7.2(7)ES139.
Multiple occurrences of this issue have been observed since October 14, 2010
and on all Unified ICM/CCE releases. This is not a regression defect. The issue
occurs when a Microsoft SQL Server query operation is performed to compare the
'lastUpdateKeys' on AW and Central Controller/Logger, during the incremental
copying of configuration changes to the local AW. In addition, using the ICMDBA
tool to backup and restore the database with "Truncate Config Message Log"
option checked can lead to a similar issue that causes the ICM/CCE Router to
reject configuration updates. No UpdateAW restart is observed in this
situation.
I mistakenly thought it was caused by the SQL upgrade from 2000 to 2005.
By the way, regarding defect CSCtj65060, I NEVER check that "Truncate Config Message Log" option when exporting the config.

Geoff

Database restore from SQL 2000 to SQL 2005 for SBO 2005B

Hi Everyone,
I am facing some problems in regards to the restore of SBO Database from SQL 2000 to SQL 2005.
Let me explain you the problem.
See I am using SAP B1 2005B with patch level 38 in my laptop with SQL 2000. I have made an company in this and done work in it as a production company and now I want to restore this company in the server which has SQL 2005. How to do it.
I have taken a backup in my laptop from SAP B1 Server Suite Manager which has SQL 2000 and sucessfully backed up but when I am trying to restore in the server which has SQL 2005 I am getting the following error in SQL 2005 in server :-
Restore failed for Server 'DXBAP001'. (Microsoft.SqlServer.Smo)
System.Data.SqlClient.SqlError: Directory lookup for the file "C:\Program Files\Microsoft SQL Server\MSSQL\data\SBO_DCHAR.mdf" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.Smo)
Please let me know the solution for it.
Thanks in Advance.

Hi,
In SQL 2005 create a database and name as the 200 one was (though any name would do). when you create the database note the location of the .mdb and .ldf file.
once this had created right click on your new database > tasks > restore database
in the new window select from device and point it to your .bak file created from your 2000 system, ensure you put a tick in the restore box on the new line.
in the options tab tick overwrite database, and, change the file locations in the restore as directory to the file locations of the new database. the file names must be the same too.
you can change the original file names after the restore.
that should do the trick.
thanks,
mike

This is what I found by someone else;
I know it's probably too late to help with the original poster, but we had this same issue and nothing we tried resolved the problem. Finally, we opened a technical incident with Microsoft and this is the solution that we were provided:
Take backup of below registry key.
HKLM\SOFTWARE\Microsoft\Cryptography\MachineGuid This key should ideally have the GUID of the machine without curly braces, so {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} becomes xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Then delete the braces.
Try to reboot and start the SQL service . If service don’t start then Uninstall and reinstall SQL.
The above solution worked on two separate machines exhibiting this problem.

SQL 2005 mirroring : Abrupt Automatic failover

hi All,
We have a SQL 2005 SP4 mirroring setup of 15 DBs with Principal(P), Mirror(M) & Witness (W).
We have now seen abrupt DB failovers for some of the databases (yest it was 4 out of 15) from P to M.
Errors were seen on Witness server as follows for all Dbs that failed over:
Date 07/01/2015 11:07:48 PM
Log SQL Server (Current - 08/01/2015 12:00:00 AM)
Source spid19s
Message
The mirroring connection to "TCP://<server.domain.com>:5022" has timed out for database "<DBName>" after 10 seconds without a response. Check the service and network connections.
Actions taken:
1. Network and Firewall team reverted that no error detected and no network traffic between the witness server and db server during the db auto failover period.
2. On the system side, we have verified that no hardware error found on either VM or SAN storage, and no Symantec SQL backup jobs running nor anti virus scanning during the db auto failover period too.
3. We did see some high amount of IO activity on P server around failover time. Some IO errors similar to below were seen, however point to note is these errors were not only for the DBs that failed over, but for others including TEMPDB:
Date 07/01/2015 11:07:38 PM
Log SQL Server (Current - 08/01/2015 4:06:00 AM)
Source spid2s
Message
SQL Server has encountered 1 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file [R:\SQLDATA\MSSQL.1\MSSQL\Data\<DBName>.mdf] in database [DBName] (5). The OS file handle is 0x000000000000095C. The offset of the
latest long I/O is: 0x0000054ff22000
Questions:
1. I assumed that the Witness keeps polling P & M on DB mirroring endpoints (in our case 5022) to check that the DBs are online, but Network team says there is no activity on that port, is my understanding correct?
2. Is there any other reason for DB failover ?

Any help is highly appreciated!!!

This is common with Mirroring server it is not as resilient to changes as log shipping. Are you aware about
below fact although not directly related to your question
If you plan to use high-safety mode with automatic failover, the normal load on each failover partner should be less than 50 percent of the CPU. If your work load overloads the CPU, a failover partner might be unable to ping the other server instances in
the mirroring session. This causes a unnecessary failover. If you cannot keep the CPU usage under 50 percent, we recommend that you use either high-safety mode without automatic failover or high-performance mode.
Now to your problem
The mirroring connection to "TCP://<server.domain.com>:5022" has timed out for database "<DBName>" after 10 seconds without a response. Check the service and network connections.
I would say there was network dip for more than 10 seconds and since default failover time is 10 seconds and for few databases witness thought principal cannot be reached it initiated failover.
Network team is incorrect to say there was no dip (its common with NOC team not to take responsibility)
