What version of ATI do you have?

I have always bought ATI perpetual. I started with 1 copy ATI 2015 but upgraded that to ATI 2017. I also bought a full version of ATI 2017. ATI 2017 had a bug where option to automatically delete old backups wouldn't stay selected. That caused backups to fail because the backup drive would be full. I had to manually delete the old backups to continue.I bought ATI 2018 for my main computer because the bug was fixed. Also, they added the ability to back up my phone. I stopped using that when I bought 3 copies of ATI 2021. ATI 2021 was a big disappointment. It's interface was painfully slow and the last update broke phone backups. Acronis supported was no help. I talked them into replacing the licenses with 3 of ATI 2018. I am now running 4 copies of ATI 2018. No problems with ATI 2018. I have used the restore file and whole disk several times with no problems.
