What Is a Website Backup and How Often Do You Need One?

Imagine your website disappears tomorrow, lost to a hack, a failed update, or a hosting problem. Without a backup, rebuilding it could take weeks and cost a fortune. With one, you could be back online in minutes.

A backup is simply a saved copy of your entire site, stored safely so it can be restored if something goes wrong. It is the single most important safety net a website can have.

Why backups are non-negotiable

Things do go wrong: sites get hacked, updates fail, files get deleted by accident, and hosting can let you down. Any of these can leave you without a website and without an easy way back.

A recent backup turns a potential catastrophe into a minor inconvenience. Instead of rebuilding from nothing, you simply restore the last good copy.

How often to back up

How often depends on how often your site changes. A shop taking orders or a site with a busy blog should be backed up daily, so very little is ever lost.

A simpler site that rarely changes can be backed up less frequently, but even then, regular automatic backups are wise. The question to ask is how much work you could afford to lose.

Where backups should live

A backup stored only on the same server as your site is risky, because if that server fails you lose both at once. Good practice is to keep copies somewhere separate and secure.

Just as important, a backup is only useful if it actually works. Backups should be tested occasionally so you know they will restore cleanly when you really need them.
