sql server 2008 R2 remote backup timeout expired

Hi,

I have a remote routine to backup a SQL Server 2008 R2 database. The routine run in a different server of the database. So, I use the following command:

BACKUP DATABASE [<database name>] TO DISK = '\\<local server name>\BACKUP.BAK'

I do not connect to the database with the "sa" user, but with the database owner user, and the routine work well until now.

The problem is that now I get the error below when I run the routine:

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. When execute the SQL command (BACKUP DATABASE [<database name>] TO DISK = '\\<local server name>\BACKUP.BAK')

How I fix this?

It is important to remember that, as I haven't the "sa" user credentials, I can not  change parameters of the SQL Server installation. Also, due to the strict security policy,  initially my client does not permit this type of change.

Thanks in advance,

Marcelo Camarate

I don't think it's a permission issue.
You should check if it's some heavy process running at same time and also check if the network bottleneck.

Hi Vitor,

Thanks for your reply.

I know that is not permission issue because, as I said in my last post, the routine work well until now. But, in the last two days I try to run it at several moments of the day without success. Therefore, the user that I connects to the database have permission to execute this command.

I said about permissions only in relation to change some parameter of the SQL Server installation, because I don't have the "sa" credentials.

Any other ideas?

Hi Vitor,

Today, at 2:30 AM, I tried running the routine and the same error occurred.

The image below shows the existing infrastructure

INFRASTRUCTURE
I access the APPL_SERVER through a remote connection using an administrator login. Then, I establish a connection to DATABASE using a user that is owner of the database that I want to backup, and run the following command.

BACKUP DATABASE [<database name>] TO DISK = '\\APPL_SERVER\BACKUP.BAK'

Note that the path is in the network ("\\APPL_SERVER"). Ie, to the server that I'm logon. And it had been working fine until last week.

The problem is that don't have tools for network monitoring installed in APPL_SERVER, and I can not install any tool of this kind because the infrastructure is in my customer. Also, I haven't any user credential to login DATABASE_SERVER.

But I need to resolve the issue as soon as possible. Then, do you know (or other expert) a similar tool of the Microsoft Database Publishing? It does not work SQL Server 2008, because it was embed in Microsoft SQL Server Management Studio 2008, tool that also I can not install in APPL_SERVER in accordance with the policies of my customer. Would be ideal, because the Database Publishing generates a script to create/charge the database.

I'm waiting for your next suggestions.

I'm sorry Marcelo. Somehow I missed your comment.
The database owner is a Domain Login or a SQL Login only?

Hi Vitor,

The database owner is a SQL Login only.

That's why you couldn't have this working. A SQL Login doesn't have access to a network share. You'll need to run the BACKUP command with a Domain Login and that Login must be at least member of db_backupoperator role.

Hi Vitor,

This is exactly why I closed this topic and open another titled "SQL Server - Web tool to backup / restore". You could read it and suggest something.

Thanks and Regards,
