Set up automatic MySQL server backups to Cloud Files from Windows
This article shows how to set up automatic MySQL server backups from your Windows Cloud Server to your Rackspace Cloud Files container. Follow these three steps to perform this task.
- Download and build a small piece of software to upload a file to Cloud Files.
- Create a .bat file to take the backup of your MySQL server database and upload it to Cloud Files using the software created in the previous step.
- Create a scheduled task in Windows to run the above .bat file from step 2 at a scheduled date and time.
Download and build the upload software
First you will need to download a small piece of C# software and compile it on a Windows Cloud Server. Use the following steps to build the Cloud Files upload software:
Extract the software into your C: drive.
For example, C:/upload-to-cf-cs-0.1/.
Download and install NAnt, a free .Net Build tool.
After you have successfully installed NAnt, open a command prompt, navigate to the directory C:/upload-to-cf-cs-0.1 and run
You should see output similar to the following:
C:\upload-to-cf-cs-0.1>..\nant-0.90\bin\NAnt.exe NAnt 0.90 (Build 0.90.3780.0; release; 5/8/2010) Copyright (C) 2001-2010 Gerry Shaw http://nant.sourceforge.net Buildfile: file:///C:upload-to-cf-cs-0.1/compile.build Target framework: Microsoft .NET Framework 2.0 Target(s) specified: build build: [mkdir] Creating directory 'C:\upload-to-cf-cs-0.1\bin'. [csc] Compiling 1 files to 'C:\upload-to-cf-cs-0.1\bin\upload-to-cf.exe'. [copy] Copying 2 files to 'C:\upload-to-cf-cs-0.1\bin'. BUILD SUCCEEDED Total time: 1.9 seconds.
The above command will compile the binary file
upload-to-cf.exe. You will be using this binary file to upload your backup files to Cloud Files. You can test this command using the following syntax:
upload-to-cf.exe [cloud username] [cloud api_key] [container name] [file path]
Create a .bat file for taking backups
Next, you need to create a .bat file to automate the MySQL database backup procedure. You should back up the MySQL database backup file to a date-stamped file. There are several ways to do this, but the easiest way is through a batch file. The command we’ll be using is as follows:
c:\<path-to-mysql>\bin\mysqldump -u[user] -p[password] --result-file="c:\<path>\backup.%DATE:~0,3%.sql" [database name]
Replace the values for
[database name] with your MySQL information. You can try this command from the normal command prompt to make sure that it works without any problems before actually including it in a .bat file. The above command should end up with a .sql file containing a full dump of the MySQL database, with the name you provided at the end of the above command.
After verifying that the above command works, create a .bat backup file (for example, mysql-backup.bat). It should look similar to the following:
@echo off echo "Running dump... " c:\<path-to-mysql>\bin\mysqldump -u[user] -p[password] --result-file="c:\<path>\backup.%DATE:~0,3%.sql" [database name] echo "MySQL dump done!" echo "Uploading to cloud files" upload-to-cf.exe [cloud username] [cloud api_key] [container name] "c:\<path>\backup.%DATE:~0,3%.sql" echo "backup file uploaded to cloud files!"
Note: You need to replace the values in  brackets with actual values for your system.
Now you should be able to run mysql-backup.bat from a command prompt. If it works, you should see a success message, and a file should be generated in the directory you specified. If not, make sure you have the correct username, password, and database values specified and then try it again.
Create a Windows Scheduled Task
Now you have a mysql-backup.bat file that creates the backup of your MySQL database and uploads the file to Rackspace Cloud Files using the
upload-to-cf.exe program. The next step is to create a Windows Scheduled Task so that all the above steps run automatically at a scheduled date and time. Follow the steps below to setup a scheduled task in Windows.
Click Start > Run, type “cmd”, and then click OK.
At the command prompt, type “net start”, and then press ENTER to display a list of currently running services.
If Task Scheduler is not displayed in the list, type net start “task scheduler”, and then press ENTER.
At the command prompt, type the following command and then press ENTER:
schtasks /create /tn "MySQL_Backup" /tr c:\apps\mysql-backup.bat /sc Value /st HH:MM:SS /ed MM/DD/YYYY
You might have to change the parameters for your situation. For example:
C:\Documents and Settings\Administrator>schtasks /create /TN "MySQL_Backup" /TR c:/mysql-backup.bat /SC daily /ST 08:00:00 /ED 12/31/2014 The task will be created under current logged-on user name ("win2k3r232bit\Administrator"). Please enter the run as password for win2k3r232bit\Administrator: ********************** SUCCESS: The scheduled task "MySQL_Backup" has successfully been created. C:\Documents and Settings\Administrator>schtasks TaskName Next Run Time Status ==================================== ======================== =============== MySQL_Backup 8:00:00 AM, 4/19/2011
This example schedules the MySQL_Backup program to run once a day, every day, at 8:00 A.M. until December 31, 2014. Because it omits the
/mo parameter, the default interval of 1 is used to run the command every day.
During the task creation you will be asked your currently logged in user’s password. After you enter the password, a new task will be created for you. You can view the newly created task with the
