I don't know why this is not called "Premium" plugin.
I have been using free copy (thanks) of Updraftplus Backup/Restore.
It is one of the few plugins I consider essential for your site.
Updraftplus Backup/Restore has been generously doing backups on my Google drive. I wanted to download and check whether it will work or have some glitch. For you require Backup/Restore during time of crisis, an emergency. I didn't check (lazy) as I was taking frequent manual backups too.
Today when I have to reinstall the whole site after a dreadful Forbidden 403 error I opened the backup files for the first time. On comparing them with manual backups with FTP I found the contents were well preserved by Updraftplus. Updraftplus has been doing this for me every day. (Great).
I had phpMyAdmin backup too. However, this time when I used this backup method it said something about Droptables and directed me for details to another page.
After reading the Updraftplus guide under restore I decided that I may restore my manual FTP backups using FTP.
I may seem to be knowledgeable in web matters with the splatter of some terms. However, I am a beginner. It means, if I can understand and use Updraftplus any other beginner like me can.
Yes, it's reliable and easy to use. You can sleep (relatively) safely with Updraftplus Backup/Restore doing the job for you.
It is to me a "premium" plugin. If I meet the guys at Updraftplus I will shake hands with them and thank them personally. High quality freeware such as this enables me to deliver best quality free consultations on line.
