Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
It seems the file permissions on that backup system can’t access that file. Anyway, you don’t have to back up the sitemap cache (it is the best to avoid troubles when restoring the backup), so I recommend you to exclude the sitemap-cache folder from your backup.
Looking forward to helping you. Thank you.

Hello,
I disabled my cache plugin but still get the same error. How do I turn this off?
Hello,
The cache of the sitemaps is created by Rank Math, not by your cache plugin. To fix the issue you could fix the permissions to access that folder (try to set them temporarily to 755) or you could set the backup program to ignore that folder (which you don’t need to backup since it is just a cache).
Looking forward to help you.
