SQL 服务器备份到共享文件夹

Question

I'm trying to make a backup to a network shared folder with the following code:

string filePath = ("\\pc-usuario\folder\backup\backup.bak")
string connectionString = String.Format(@"Data Source={0};Initial Catalog={1};Integrated Security=True;MultipleActiveResultSets=True", server, database);

using (var connection = new SqlConnection(connectionString))
{
    var query = String.Format("BACKUP DATABASE [{0}] TO DISK='{1}'", database, filePath);

    using (var command = new SqlCommand(query, connection))
    {
        connection.Open();
        command.CommandTimeout = 1800;
        command.ExecuteNonQuery();
    }
}

Got the following error:

The backup device cannot be opened. Operating system error 5(Access denied.).

If I try it with SQLExpress the same error happens. What am I missing?

Answer 1

You havent given the database backup a file name, only a file path

Eg the final code should read

backup database wibble to disk = '\\pc-usuario\folder\backup\wibble.bak'
