Hello,
I'm getting the same error message on my test VM without lve_suwrapper as well:
[[email protected] ~]# /usr/local/cpanel/scripts/cpbackup
[cpbackup] Backup Not Enabled (This can be adjusted in WHM => Backup => Legacy Backup Configuration)
Please try to add 'lve_suwrapper 50' to the cron task, so it should look like this:
0 1 * * * lve_suwrapper 50 /usr/local/cpanel/scripts/cpbackup
