Yes, without question. A backup is the difference between an inconvenience and a disaster. Your host's backup is a start, but it usually only goes back a few days and lives in the same place as your site.
The short version
Everything that makes your site yours - pages, posts, orders, customer records, settings - lives in one place. When that place has a bad day (a hack, a failed update, a server fault, a deleted file), the only thing that brings it back is a backup taken beforehand.
What a proper backup looks like
It covers both the files and the database. It's taken automatically, on a schedule, so it doesn't depend on someone remembering. It's stored somewhere separate from the site itself, so one server problem can't destroy the site and its backup together. And it's been tested - an untested backup is a hope, not a plan.
How often
For a site that changes, daily. For a quiet brochure site, at least weekly. The rule of thumb: you should never stand to lose more work than you'd be comfortable redoing.
Where we come in
Every care plan we run includes automatic daily backups plus off-site copies kept long-term, and we test restores rather than assume them. If you'd rather handle it yourself, our maintenance checklist shows what to set up.
