Duplicator vs UpdraftPlus: the record
Across 5 recorded battles, UpdraftPlus leads 5 to 0. It has taken every decided run in this matchup, which is a consistent result rather than a close one. Elo currently has them at 789 (Duplicator) against 994 (UpdraftPlus).
Backup and restore speed
Backing up, Duplicator averages 18.6s against 10.0s for UpdraftPlus. Restoring, it is 7.8s against 5.0s. UpdraftPlus is ahead on both phases, by 46% on backup and 36% on restore. A plugin that leads both is a simpler recommendation than one trading a fast backup for a slow recovery.
What each one actually backs up
These two do not back up the same thing, which is the part a speed chart cannot show you. UpdraftPlus archives wp-config.php where Duplicator does not. Time spent archiving more is not waste, so comparing seconds alone rewards whichever plugin does less.
Archive format and size
Duplicator writes a ZIP archive, deflating each entry as it goes, averaging 83 MB. UpdraftPlus writes a gz archive with compression, averaging 69 MB. That leaves UpdraftPlus about 14 MB smaller per backup, which compounds against every copy you retain. Both compress, so the difference in size reflects what each one packed rather than whether it bothered to squeeze it.
Which should you choose?
If your backup window is the constraint, UpdraftPlus finishes first; if you want the archive to stand on its own, UpdraftPlus captures more of the site; if you are paying for retention, UpdraftPlus writes less per copy. Every figure above links to the run that produced it, including the logs, so none of this has to be taken on trust.
Common questions
- Which is faster, Duplicator or UpdraftPlus?
- On the runs recorded so far, UpdraftPlus backs up faster, averaging 10.0s against 18.6s. The same plugin is also quicker to restore. Speed alone does not settle it, because the two plugins do not always archive the same content.
- Do Duplicator and UpdraftPlus back up the same files?
- No. UpdraftPlus includes wp-config.php, which Duplicator leaves out. A smaller archive is not automatically a better one, and a faster backup is partly explained by there being less of it.
- How big are the backups?
- Duplicator averages 83 MB per backup and UpdraftPlus averages 69 MB, measured on the same site profiles. Multiply by however many copies you keep before deciding the difference is academic.
- How does Backup Arena measure this?
- Both plugins run inside identical Docker containers against the same WordPress snapshot, on six hosting profiles ranging from constrained shared hosting to a dedicated box. Each configuration runs a discarded warm-up followed by three measured iterations, and the site is reset to a verified snapshot between every run. A backup that will not restore is a loss regardless of how quickly it was written.
- How much should I trust these numbers?
- This matchup has 5 recorded battles, which is enough to be indicative and not enough to be final. Every run is published with its logs so you can check the workings, and reruns can be requested.
