Best Way To Backup A Website?

the best way to backup a site is use cpanel and its backup feature.
or else you can go for backup servers available for premium members.
lots of backup service providers are available online.

I actually don't like that feature, except for the SQL part. For files, I prefer to go via FTP, as it takes much less time.

I would recommend backing up using Cpanel - it can backup your whole site including databases, and encrypt them if you want.

It is a very good idea to back up frequently. Especially if you have a lot of user submitted content in databases.

You may want to use automated backups of databases, every day of week or even every few hours. the HTML files should be backup up frequently, but depending how often they are updated.

If you are using some web-based applications having backup feature, e.g. Discuz! (a BBS software), you may consider it first. Then you may consider phpMyAdmin, assume you are using both PHP and MySQL, as its backup function is greatly configurable, for example, selecting tables, compression method, and I have not encountered any problem regarding its outcome yet.

There are three things to consider for me while backing up a site, :
a. The first thing to know is what is your website content, which means that you shouldn't back up the wrong things. Usually files and databases are main back up procedures.

b.You can download all the files from the public_html to your desktop computer, and than reaarrange the ones needed for the future and make whatever you want.
c.Or you can just constantly back up only back up databases, usually mysql databases, if you are not making much improvements to the site.

I prefer full back up of a site.
