I wouldn't touch Acronis.
After I saw your response it came to me.
I haven't used Acronis for Windows in quite some time.
I switched over to Macrium Reflect.
It's still installed on my machine I just don't use it any longer.
Is there anything for Mac you would recommend Richard?
I prefer to use something in addition to Time Machine.
From what I understand TM does a backup but only on most of the files.
If you have to do a major re-install TM restores many of the files but there are several system files it does not backup and requires several hours of downloading.
I would prefer to also have a disk image of everything on the drive.
If I need to replace a drive by cloning or have a major disaster I can be up again fairly quickly compared to TM. My problems with SD started when I reached a version where it had to reformat the backup drive to APFS. Right now it will not finish a complete backup. If I start a backup if never finishes and I am not successful in telling it to stop. It just keeps running until I literally have to forcefully power down the machine. Even telling the Macbook to shut down will not work. Disk Image does not work either.
