I have used Acronis for more than a decade. However in the last years their approach to marketing makes it a very unattractive option (they started to sell 1 yr - time limited licenses - you have to pay again if you want to continue using it, even locally).
I would be interested in a replacement software with one-off license fee. I use it two-ways:
- C: disk backup, so I can restore system if the disk fails
- regular directories/files backup
