I am not sure if this post belong in this forum or the Windows Guest Forum, so if it is in the wrong place I would appreciate it if one of the moderators would move it. I was going through some of the general settings for my Windows VM when I noticed the Acronis software offer for backing up the VM. I am familiar with Acronis since I used their backup software when I worked on Windows, but I wondered if there was any particular reason to not use other backup software for the VM. I know that the recommended settings are for Time Machine to not back up the VM but, since my VM pvm file is on an external ssd, Time Machine does not see it anyway. I have been backing up my VM pvm, along with everything else on my usb 3 ssd, with Carbon Copy Cloner but the Acronis offer made me wonder if there is some reason for not doing that. That is, is there any particular reason for using the Acronis software rather than some other backup software for backing up the VM pvm file? Is there something particular about the file that makes backing it up with regular backup software fail?
