Question

Why do I see 'You do not have the feature “backup”.'?

Answer

If you attempt to generate a user backup using the uapi Backup API call documented at Back up cPanel account to home directory

and you see error output of

func: fullbackup_to_homedir
module: Backup
result:
data: ~
errors:
- You do not have the feature “backup”.
messages: ~
metadata: {}

then the feature list used by that user needs to have "Backup Manager" enabled.

Please refer to the following on creating a feature list.
