Acronis Backup charges you for local data backups from one device to the other. So basically if you are using Acronis to move data from your local drive to another local device like a NAS, you pay money for every gigabyte transferred. During the time I worked for them, the script to run the transfer was literally the most simple robocopy command, even simpler than one you could write yourself. And they still do it, charge for local to local data movement. Its fucking insane. One of my clients had a $15k a month bill for local data movement. Straight up highway robbery.
I know a lot of MSPs who sell this product because it makes them tons of money. I find it to be completely evil to make your customers pay for something that shouldn't cost anything.
