How do I make a safe backup and as a Restore?

The best recommendation is that you proceed manually. To verify that the individual routes are also made really, backup components have several problems since. Joomla Component Pack is indeed safe to recommend a component, but also can be nasty surprises when you do not fit in it is to use these correctly.

Go to the server via ftp and secure all existing folders and files there by going to your local computer to transfer them. For full, please click on the image.

Backup settings php MyAdmin

Tip:
You can also activate Drop Database and Drop Table function with that result, including the database tables and content is automatically deleted when an import, before the new database tables and content are recorded.

So you have made a complete backup of your pages and the database.

The restore works in roughly the opposite.

You transferring the folders and files from their backup to the server via ftp, then go into the PHP My Admin database field and examine the database, or for damage to it, you should delete the database and reinstall it. Once this is clear, use the import feature of the database and play the previously made backup database (a dump). (Archive unzip locally and the import) For full text file, just click Zip.

Import php MyAdmin

Since you have selected the complete inserts and create Table, the data and the tables are completely restored.

Moving on to a server, you need to adjust the configuration.php in the root directory of Joomla with the new password and you're done.
