How to securely set up Rackspace Cloud Files for backups
Rackspace Cloud Files allows you to set up users that have access to only one container in your Cloud Files account – and to nothing else. This is the most secure configuration. It means that admin users on your WordPress site, even if they can copy the Rackspace access details from the UpdraftPlus configuration, can do nothing more with them than access the UpdraftPlus backups.
The easiest way to set up Rackspace Cloud Files in this way is using Rackspace Cloud Files enhanced, a feature of UpdraftPlus Premium.
