You don't need Linq to backup a database. What is it that you want to accomplish?

I've created a SQL database beside my exe file, I'm trying to take backup from it through my application.
At first , I've used File.Copy, but I receive this Exception cannot access because it is being used by another process
Could you guide me, how I can do it ?

Perhaps your application? If the app uses a mdf file as a resource then it is possibly loading the file at start up. That should give you a start of where to look.

Run normal backup code from your application, rather than to use File.Copy. File.Copy needs the mdf files to be detached from your server instance which is not good technique.
BACKUP DATABASE [DbName] TO DISK = N'C:\dbName.bak' WITH NOFORMAT, NOINIT, NAME = N'DbName-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10
Just change the dbName, disk location for your backup and Name of the Backup file and run this using command.ExecuteNonQuery().
And believe me... you dont require LINQ for doing this .

Thanks Abhishek Sur.
I'm using LINQ, so I've used the following code :
public static void GetBackUp()
{
if (!Directory.Exists(StaticVariables.BackUPFolder))
Directory.CreateDirectory(StaticVariables.BackUPFolder);
using (RezaRestaurant.SQL.DataClasses1DataContext dbc = new RezaRestaurant.SQL.DataClasses1DataContext())
{
dbc.ExecuteCommand(@"BACKUP DATABASE " + dbc.Mapping.DatabaseName + " TO DISK='c:\aaa.bak'");
}
}
and this Exception has occurred :

I have a project to convert a database from Postgresql to SQL Server. I know of tools to convert the database from one to the other but all I have are scripts right now. Does anyone know of a utility that can take scripts created for Postgresql and create a SQL Server database from them?

Depending on the size of the database it would almost be worth installing postgre just to use the conversion tools. I'm assuming they have an express type product.

There is no express version but I already have Postgresql installed. The problem in the scripts I've been provided with won't run. I wanted to try converting them to TSQL and running them against SQL Server directly since the ultimate goal is to port it to SQL Server anyway.

Sounds like a hand job to me  That my double entendre for today....
I'd try splitting the scripts to types ie tables, procs and views, see if there are any standard conversions and try running them individually. Sounds like a LOT of work even if there are no constraints and key involved. I'd go back to the client and try and get a backup.

Trying. Unfortunately, I've taken over this project after the original team's failure. They are uncooperative to the point of potential legal actions by the client. I had the suspicion that it would a tedious manual process but had ask just in case.

As others have said, this is going to be a tedious manual process.
I work with Ingres and SQLServer on almost a daily basis; Ingres isn't PostreSQL, but I'm assuming it isn't too far off either.
If you have the scripts to create tables, etc, can you write a script to extract the table name, columns, datatypes and null settings? Having these, you should then be able to script the tables creation in SQLServer.
I will help as I can.

I have a sql server 2008 database installed on windows server 2008, I enabled remote access to it and enabled TCP/IP and added rules for the TCP/IP port on the firewall exceptions and I restarted all sql server services.
I try to connect to the database from my pc remotely using the sa account but it fails.
I even created a new user account and tried to connect using this account but also fails.
What am I missing?
Do I have to download sql server 2008 on my pc to connect to the database remotely instead of sql server 2005?
can someone help me out?

What is the Error that you Receive ?

I believe that you do. Given that it should not take too long, depending on the speed of your connection, I would try that. The reason I say that is because I have 2005 and 2008, on two different PCs and 2005 will not connect to a copied 2008 database.
However, as Vuyiswa Maseko asked, do you get an error message? The answer to that might help to pin down the problem.

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 -

I have seen a lot of people all over the web with this same problem so I will let you know how I fixed my problem with it and maybe it will help someone!
Firstly, go into IIS Manager and click on your website or directory.. on the right hand panel there is a connection strings option - dbl click on it and it will tell you what your default local sql server is set to.. somehow mine got all screwed up so that was part of my problem.. hopefully that is ALL of your problem (some of you anyhow).. 
For me it was more complex however.. I was also trying to do personalization for anonymous users.
Thus, in my web.config there were two sets of connection strings..
one was labelled thus:
<appSettings>
<add key="ConnectionString" value="server=localhost;database=caleb.mdb;uid=;password=;" />
</appSettings>
..so I thought I was using MS Access.. but there was another Connection String attribute like this..
Somewhere else I found this kind of connection string..
<connectionStrings>
<add name="LocalhostCTP6" connectionString="Data Source=localhost;Initial Catalog=CTP6;User ID=dnn;Password=dnn" providerName="System.Data.SqlClient" />
<add name="DynamicConnection" connectionString="Data Source=localhost;Initial Catalog=CTP6;User ID=dnn;Password=dnn" />
</connectionStrings>
<appSettings>
<add key="ConnectionInfo" value="server=(local);database=Northwind;Integrated Security=SSPI" />
</appSettings>
(see this article[^]
If you arent sure which connection string is actually being used by your program, you can use this code..
[^]
..and to complicate things more, an external file can be involved too as it was in my case!!
<appSettings file="testlabsettings.config"/>
and as if things werent already complicated enough it is possible to add connection strings on the fly at run time see
http://www.kodyaz.com/articles/add-connection-string-to-web-configuration-file.aspx[^]
(luckily for me, noone was doing this as far as I know!!)
So there you have it guys.. if that doesnt solve your problem I will eat my hat!

I've just installed sql server 2008 but still not working.
I have a feeling that the server name is not correct. Can you tell me how to write the server name??
I have access to the server and the database on the server. When I access the database locally I write for example ("MyServer,portnumber")
but remotely, I can't seem to access it using the same server name.

You might try visiting ConnectionStrings.com[^], a very useful site.
I know that you are not using a connection string but the site shows many variations on the machinename/servername combination.

I've tried everything. Still cannot connect. I used the IP address of the server but still can't connect.
Is there anything I can do on the server to enable remote connection..I've done everything I can thing of..am I missing something?

yes, u r right. u can't connect to sql server 2008 via sql server 2005. i also faced this problem. and in fact sql server 2005 express can not upgraded to sql server 2008 so first u have to uninstall sql server 2005 then install sql server 2008.

thanks a lot, I'll install sql server 2008 and try again.

How can I get the correct server name to connect to?
I have access to the server, can you tell me how to get the server name if I want to connect remotely??
