Backups are an important task that you should keep in the back of your mind.
You should set a schedule to complete these Backups regularly. Perhaps on the first of the month?
Most programmers experienced with software and data storage recommend that you keep 3 copies of your Backups in various locations. I keep one on my computer in a dedicated directory, I keep another on my external drive and a third is available on a dedicated Thumb drive. This way if I loose the computer hard drive and the Thumb drive is corrupted, I can still retrieve my data.
Backups should be done before any major changes to your site, when installing a new plugin or when upgrading your WordPress installation. If you make a copy BEFORE you make your changes you have a way to go back and undo your changes should anything go wrong.
This process will allow you to back up the content of your site. If you want to reinstall this to another location you will still need to install the WordPress onto the new location first then restore your files from inside WordPress.
Lets Get Started:
Log in to your site. This is done by entering the name of your site followed by /wp-admin.
Enter your user name and password
*Note: You should ALWAYS change the UserName from Admin. This is done for demonstration purposes only
