Oooh, I would give the name of the plugin I chose as an alternate, but I think the plugin author will dislike me posting that here.
I prefer the BackWPUP, when I can use it, but with GoDaddy, that was not possible.
Just do what I did, which was perform a little Google research (reviews) on WordPress backup plugins and there are a number of other good ones. Choose one, try it and see if it works in the GoDaddy Managed WordPress environment. If not, go to the next one. That is what I had to do.
If its just backing up you want, try to focus on finding a plugin that does the job and is not bloated with a lot of other unwanted features.
Always do a scan of your website for malicious malware, HTML pages and scripts with a good plugin before any backup.
Then, ensure that the plugin backs up WP folders, not just the SQL database and check that it occurred. I did not check one time as I should and only had the SQL backup.
Most of all, after the scan, ensure a copy wp-config and htaccess file is included in the backup.
I used one of the cloud storage services and saved a copy to my backup hard drive. Since this is part of my business, redundant backups are always a good measure.
