Ok so let’s get going:
1. Create the file “backup_database.php” and input the following code into it:
<?php exec(‘cd /home/your_user/backup/db/;mysqldump –add-drop-table -h localhost –user=your_user –password=your_pass database_name > `date +%y-%m-%d_%H-%M`.sql’); ?>

Sometimes the path to your home dir looks different than ‘/home/your_user/’, so execute the ‘pwd’ command like explained in my previous post

Here we use the command mysqldump in a tutorial that I wrote previously about the dumping the sql database from one host to another. Now the database will be saved directly on the server that is hosting your website

2. Create /backup/ and /backup/db/ directories via SSH or FTP if not created.

Of course you can use any names. But better do not create the /backup/ directory in the /public_html/ directory for security reasons

3. Upload “backup_database.php” to the /home/your_user/backup  directtory

If you upload backup_database.php to www.yoursite.com/backup_database.php by accessing it directly in your browser you will create a backup of your database.  However I do not recommend doing this First because someone can overload your space quota by accessing the backup_database.php many times and second because you probably don’t want to enter the URL in your browser every time you want to perform database backup.

4. Go to CPanel -> Cron Jobs and input the path to backup_database.php:

Click on the `Add new Cron Job` button…     and you are pimped out. In my case I added the option this cron job to be executed twice a day. In case you database is updated more often/rarely you can modify this setting to suit your needs.
You can also add option to save the dump of the database in tar format to save some space in your hdd quota by changing the script a bit.
Full database backup in tar format (save more space):
backup_database.php:
&lt;?php exec(‘FILE=`date +%y-%m-%d_%H-%M`;cd /home/ps3igri/backup/db/;mysqldump –add-drop-table -h localhost –user=your_mysql_user –password=your_pass db_name > $FILE.sql;tar czpf $FILE.tar $FILE.sql;rm -f $FILE.sql’); ?>
As you see here we use the ‘FILE’ variable to store information about the filename. We create a SQL Dump, then we archive it, and after that we delete the original file to save some disk space.
Good luck with the backup and see you next time

and after that executing the code by opening http://www.yoursite.com/exec.php in your browser.
So we can add this line directly into the Curl command field:

But now I am going to tell you better way to do it, because very often the commands directly typed at the cron’s `Command:` field are ignored because of some stupid quote convention etc.
Full website filesystem backup using php file and cron job:
1. First we are going to create the file backup_filesystem.php and put this code into it :
<?php echo exec(‘cd /home/your_user/backup/files;tar -cvpzf `date +%y-%m-%d_%H-%M`.tar /home/ your_user /public_html’); ?>

2. After that we’ll access the website via the FTP and put the backup_filesystem.php file into the /home/your _user/backup/. Make sure that you create “backup” and “backup/files” directories if they are not already created. Better don’t put backup_filesystem.php file into the /public_html/ folder because we don’t want the users to have direct access to the file.

3. Now we are going back to the CPanel -> Cron Jobs. On the common settings we enter Once a day (so the Command will be executed once a day) and on the Command field we enter:
php ‘the path to backup_filesystem.php’

After that click on the ‘Add new cron job’ button and Voila !! – the Cron Job for backup of your database is ready.
The archive is created using low tar compression, so if needed you can archive your site using stronger bzip2 compression by replacing: “tar –cvpzf filename.tar” with “tar –cjf tarname.bz2”.

The full backup of your website is created in the /backup/files directory and can be downloaded via FTP if necessarily – as you see the filename include the date and time of the moment it has been created, so it won’t be hard for you to guess which is the latest version of the backup if needed.
Thank you for your time, next time I’m going to show you how to perform similar backup, but this time full database backup instead of filesystem backup.
Cheers

Securing an Apache 2 Web server can be an intimidating prospect for those new to secure sockets layer (SSL) certificates. However, this need not be the case. SSL secures Web server to Web browser connections. Read on to better understand SSL certificates, learn how to set them up on Apache and launch your SSL-enabled site.

basically i will save you some of reading the long tutorial and will get straight to the point – here are some useful commands that you are going to learn from this tutorial. I had some problem with these commands under windows so i give you my updated version – everything should be ok here

i tested that with win7 and xampp 1.7

create RSA private key
openssl genrsa -out mykey.pem 1024

create self-signed certificate
openssl req -config “xammp-dir\apache\bin\openssl.cnf” -new -key my.key -x509 -out sslname.crt

create certificate signing request
openssl req -new -key my.key -config “xammp-dir\apache\bin\openssl.cnf” -out my.csr

<IfDefine HAVE_SSL>
