How to take and restore file backups
Creating a Backup
Assuming you have setup an FTP client, the best way to create a file backup is to download the contents of your HTDOCS folder(s) into a safe location.
In most clients this operation can be done via drag-and-drop as you drag the contents you want to backup from the remote server side of the screen to the local computer side.
It is recommended to do this at least once per month and to store this backup on a removable drive such as a flash drive or CD and keep it safe.
Restoring a Backup
Again assuming you have an FTP client setup and also assuming you have taken time to backup your files and folders, restoring data is as simple as re-uploading the backup files/folders.
