Draft — every claim about the competitor below must be checked against their live site before publishing. Update “Verified on” when done.
The short version
UpdraftPlus is the most installed backup plugin in WordPress and its free version is generous: scheduled backups and cloud storage without paying. Where it charges is migration and cloning, and it charges yearly. Quick Restore flips this: migration is free on every plan, automation is the paid part, and you pay once.
When UpdraftPlus is the better choice
You want free scheduled backups to Dropbox or S3 and never intend to move the site. Its free tier covers that completely.
When Quick Restore is the better choice
You migrate sites — staging to live, host to host, client handovers — and do not want a yearly Migrator licence for it. You also prefer one file per backup instead of separate database, plugin, theme and upload archives.
