BackUp From Network Server

Hi You can use this class to do this. I am using this in my project and got the expected answer .

public class SQLLocalBackup
{
protected SqlConnection _conn;
protected string _address;
protected string _user;
protected string _pass;
protected string _dbname;
public SQLLocalBackup(string Aaddress, string Auser, string Apass, string Adatabasename)
{
try
{
_conn = new SqlConnection(String.Format("Data Source={0};Initial Catalog={1};User Id={2};Password={3};", Aaddress, Adatabasename, Auser, Apass));
_conn.Open();
_address = Aaddress;
_user = Auser;
_pass = Apass;
_dbname = Adatabasename;
}
catch (Exception ex)
{

}
}
/// <summary>
/// /// This function checks for temporary tables since we don't want to interfere with other programs/functions
/// </summary>
/// <returns></returns>
protected string findUniqueTemporaryTableName()
{
string name = "afpTempBackup";
int counter = 0;
string sql = "";
SqlCommand _mycommand = new SqlCommand();
_mycommand.Connection = _conn;
while (true)
{
++counter;
sql = String.Format("SELECT OBJECT_ID('tempdb..##{0}') as xyz", name + counter.ToString());
_mycommand.CommandText = sql;
if (_mycommand.ExecuteScalar().ToString() == "")
{
return name + counter.ToString();
break;
}
}

return name;
}
