# Does UpDraft plus interact with wp-cron.php?

 * In the past 2 weeks we have been having a lot of server downtime and our host’s
   support claims it is because of Cron scripts that are running across the domains.
   We recently installed UpdraftPlus across all our domains; does it interact with
   wp-cron.php in anyway/could it be at all related to our problem (which ultimately
   leads to Internal Server errors and Fatal Errors (“Allowed memory exhausted”).
 * Any insight is appreciated.

 * Hi Amanda,
 * wp-cron.php is the WordPress scheduling system, and hence is used by everything
   that wants to schedule anything (in this case, backups).
 * See here for more on what resources UD needs, and what can be done: [http://updraftplus.com/faqs/how-much-resources-does-updraftplus-need/](http://updraftplus.com/faqs/how-much-resources-does-updraftplus-need/)
 * Best wishes,

 * Thank you for that article David.
    So you are confirming that UpDraft Plus uses
   wp-cron.php? A lot of our host’s techs are suggesting that we get a caching plugin.
   Would that help with the overload?

 * Hi Amanda,
 * Yes, it does. Talking about wp-cron.php is synonymous with talking about WordPress’s
   scheduled task system. There’s only one.
 * Cacheing plugins do help with site load, yes – typically they reduce the time
   needed for each normal page by about two-thirds. However, whether that’ll solve
   your problem depends on whether the major bulk of the site load is ordinary pages,
   or the backup run. (They really shouldn’t be having a problem with the backup
   run, if you’ve scheduled it to run in the small hours – you should ask the host
   what hour their server is least loaded, so that you can check you’re scheduling
   it at the best time for them).
