Unfortunately, I'm not quite as convinced as the other buyers. BackupBliss is expensive in comparison and has to be rated as such.
It usually works well for smaller sites, but the free version is also sufficient. I find the quick migration via link particularly good and helpful.
With my "normal" sites, which are somewhat larger, there are always errors - sometimes during the backup, at the latest during the restore. Unfortunately, this is not something I can rely on at the moment. Support usually only responds after weeks.
Unfortunately, this will probably be my first refund at AppSumo. I have WPVivid for the same price and even though it may not be as convenient, it runs much more reliably.
