Please ask your host to correct these errors on their server configuration.

Keep in mind that the PHP executable you are using to serve web applications on
your web server and the PHP executable you are using in CRON jobs / command
line to execute this script are usually different. Different executables have
different configuration files. The php.ini file loaded for PHP $phpversion ($phpenvironment) is:

$iniFileLoaded

You need to modify that file to fix the issues listed above. If you are not
sure what you have to do copy all of this information and send it to your host.
They know what to do. Alternatively set "Secure settings" to Off in the options
page.

An error has occurred:
Could not decrypt settings for profile #$profile

The settings for backup profile #$profile are stored encrypted in your database.
However, PHP $phpversion ($phpenvironment) on your server -which you use to run this backup
script- does not support encrypted settings. Since the settings cannot be read
the backup has failed.
