Microsoft SQL Server has a built-in backup feature that you can run as a query or a stored procedure. You can configure the output file to write to an FTP folder. This tutorial explains how to accomplish this task.
Note: The scripts in this tutorial were created by one of our forum users. If you need further assistance, contact your developer.
Create the folder
First, you need to create a folder to store the backup in your FTP application.
- Connect your FTP client to the account that has the database that you want to back up.
Create a folder called backups inside the /web directory. The path to the folder should look similar to the following example:
- In your FTP application, right-click the folder that you just created and set its permissions to 766. Be aware that you are allowing all users write permissions for the folder). If your FTP client doesn’t allow this, we recommend that you use a client that does, such as FileZilla, CoffeeCup FTP, or FireFTP (a Firefox plugin).
IMPORTANT: For this specific example to work, the permissions on the _/www.domain.com and /web folders must be set to 751.
Create the stored procedure
You will also need to create a stored procedure that performs the backup with an input parameter for the file name.
To do so, connect to your SQL Server database by using the client of
your choice, and run a query similar to the following one. In this
example, the stored procedure is named
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[FullBackup] @FileName nvarchar(256) AS BEGIN SET NOCOUNT ON; BACKUP DATABASE [123456_YourDatabase] TO DISK = @FileName WITH COPY_ONLY, NOFORMAT, NOINIT, NAME = N'Full Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10 END
Create the web page
Next, you create a web page that has code to execute the stored procedure. You can use any language we support on Windows, such as ASP Classic or ASP.NET. For this task, we recommend ASP Classic, so that there is no .dll file and no application restart is needed.
Create a new ASP page and call it backupdb.asp. Edit the location path and SQL connection string. The contents of the file are as follows:
<%@LANGUAGE="VBScript" CODEPAGE="65001"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <% dim thismonth, thisday, thisyear, location, filename, ver, extention, abolutepath thismonth= datepart("m", now()) thisday=datepart("d", now()) thisyear=datepart("yyyy",now()) location="\\fs1-n03\stor1wc1dfw\838249\2382489\www.yoursite.com\backups\" filename="dbBackup-" & thismonth & "-" & thisday & "-" & thisyear & "_" ver=1 extention=".bak" absolutepath=location & filename & ver & extention set fso = Server.CreateObject("Scripting.FileSystemObject") while (fso.FileExists(absolutepath)=True) ver=ver+1 absolutepath=location & filename & ver & extention wend 'pre Create the file Dim fs,f Set fs=Server.CreateObject("Scripting.FileSystemObject") Set f=fs.CreateTextFile(absolutepath) set f=nothing set fs=nothing 'finished creating the file Set cn = Server.CreateObject("ADODB.Connection") cn.connectionString= "Provider=SQLOLEDB;Server=mssql12xx.wc1;Database=123456_YourDatabase;Uid=123456_YourUsername; Pwd=Yourpassword;" cn.open Set cmd = Server.CreateObject("ADODB.Command") Set cmd.ActiveConnection = cn cmd.CommandText = "FullBackup" cmd.CommandType = 4 'adCmdStoredProc cmd.Parameters.Refresh cmd.Parameters(1) = absolutepath cmd.Execute cn.close %> Execution complete: Filename=<%= filename & ver & extention%> </body> </html>
Schedule the cron job
Schedule a cron job to call the web page.
- Open the Cloud Sites Control Panel.
- Click on the site with the database, and go to the Features tab.
- Under Scheduled Tasks (Cron Jobs), click Add New Task.
- Specify a name for the job.
- Select the Send me an email check box and enter your email address.
- Select http as the script language.
- Enter the URL to the ASP script.
- Schedule the job to run daily at an off hour. Usually this is a late-night period, such as 1:00 a.m., when most sites experience less traffic.
