you mean they are done via the x10hosting or should i start to do them via my Cpanel???
You should always keep a local (ie on your own computer) copy of your files.
You never know what might happen with your account (suspension, etc) or with the server.
You can use FileManager to zip your public_html and then you can download it. If you have a lot of files, you can do it directory by directory.
You can use phpMyAdmin to export your MySQL database. Again, if it is really big, break the job up into parts by exporting half the tables at a time.
To be especially paranoid, email a copy of the backups to a hotmail/yahoo/gmail account.
