How to Update and Back Up a WordPress Website Without Breaking It

By Measured 5 September 2026

WordPress updates arrive weekly and every one is a small risk. The routine that makes them safe takes fifteen minutes and starts with a backup you have actually tested.

The short answer

To update a WordPress site safely: take a full backup (files and database) first and confirm it completed; if your host offers staging, update there and check the site before repeating live; update in order — plugins one or a few at a time, then the theme, then WordPress core — checking the homepage, a service page and the contact form after each round; and keep a note of what you updated in case something breaks a day later. Backups should run daily to a location other than the site’s own server, and you should restore one to staging once a quarter to prove they work. Hand it over when the site is a shop, when a major version update is due, or when the routine has stopped happening.

Why updates sometimes break things, and why you still apply them

A WordPress site is the core software plus a theme plus plugins from different authors, updated on different schedules. Occasionally one update assumes a version of another that you do not have yet, and a layout shifts or a form stops sending. That is the risk. The alternative, not updating, leaves published vulnerabilities open on a site that automated scanners visit daily; most compromises we have cleaned up came through a plugin whose fix had been available for months.

So the answer is not to avoid updates; it is to make them safe. Backup, staging if you have it, a sensible order, and a check afterwards.

Backups first, and backups that restore

  • A backup is the files (WordPress, theme, plugins, uploads) and the database (posts, pages, products, orders, settings). Both, or it is not a backup.
  • Daily, automatic, stored off the site’s own server: your host’s backup service, or a backup plugin sending to cloud storage. A backup on the same server dies with the server.
  • Keep at least two weeks of daily copies; a compromise is often discovered days after it happened.
  • Test a restore quarterly, to staging or a local copy. A backup that has never been restored is a hope, not a plan.
  • Before any update, take an on-demand backup as well, so the rollback point is minutes old.

The fifteen-minute routine

  1. Take a backup and confirm it finished.
  2. If your host provides staging, push the live site to staging and do steps 3 to 6 there first.
  3. Update plugins, a few at a time. Read the changelog for anything marked major or breaking. If a plugin has not been updated by its author in over a year, consider replacing it.
  4. Update the theme. If you have a child theme (you should, for any customised theme), the parent updates without losing your changes.
  5. Update WordPress core. Minor versions (6.8.1 to 6.8.2) are safe and can be automatic; major versions (6.8 to 6.9) deserve staging.
  6. Check: the homepage, one service page, one product page if a shop, the contact form (submit it), the checkout if a shop, and the site on a phone. Look at the browser console for errors if you know how.
  7. If anything broke: restore the backup, or deactivate the plugin you just updated and roll it back, then look for the fix.
  8. Note what you updated and when. Problems that appear two days later are usually traceable to the last round.

When to hand it to someone else

  • The site is a shop. WooCommerce updates touch checkout, payments and stock, and a broken checkout costs orders every hour it is down. Staging is not optional here.
  • A major version of the core, the theme, a page builder or WooCommerce is due. These are the updates that break things.
  • The routine has stopped happening. If the dashboard shows twenty pending updates, the habit has gone and the site is exposed; that is the moment to buy the habit.
  • PHP version changes at the host. Old plugins fail on new PHP; the host will usually warn, and the update needs someone who can read the errors.

This routine is the core of what a care plan does. Ours runs it weekly, with a backup before and a check after, as part of the £50 monthly that includes the hosting. Whether that is worth it depends on whether the fifteen minutes will actually happen every week; on most owner-run sites we take over, it has not for months.

Common questions

Questions people actually search for.

How do I update my WordPress website safely?

Back up first and confirm it completed; use staging if your host offers it; update plugins a few at a time, then the theme, then core; check the homepage, a service page and the contact form after each round; note what you changed. Roll back from the backup if anything breaks.

How do I back up a WordPress site?

Daily, automatically, files and database together, stored off the site’s own server via your host’s backup service or a plugin sending to cloud storage. Keep two weeks of copies and test a restore every quarter.

Should I turn on automatic updates in WordPress?

Minor core updates, yes. Plugins and themes, yes if your host takes a backup before each automatic update and you check the site regularly; not on shared hosting with no backups.

What order should I update WordPress in?

Plugins first, a few at a time; then the theme; then WordPress core. Major version changes of any of them deserve a staging test first.

What if a WordPress update breaks my site?

Restore the backup you took before updating, or deactivate the plugin you just updated and install the previous version. Then look for the fix or a replacement. This is why the backup comes first.

How often should WordPress be updated?

Weekly. Updates arrive roughly that often across core, theme and plugins, and each published fix is a vulnerability scanners start looking for. A fifteen-minute weekly routine keeps the site current.

Twenty updates pending and a form you have not tested?

Send the address. I will tell you what is out of date, whether backups exist, and whether the form works, and give you the routine or run it for you.
