I was looking for a tool to automatically backup a repository website which contains a lot of files and data. After Upgrading to a new server with a newer php and MySql version I had to go through the nightmare of manually inserting tables into the new database. I wish I had this tool then.
So a yesterday I purchased the version for unlimited use (99 dollar) installed it, but didn't get the automatic cronjob to work. Today I posted a ticket for support. In less then 30 minutes I received an email, granted them temporarily backend access and after some trial and error they solved the problem without having to rewrite some backend server script or use the cron functionality on cPanel (which I don't have, btw)
Conclusion: Buy it, install it, use it and have no worries!
