Acronis True Image 2020 seems to be secretly reading unrelated files on my PC
Couple of days ago I started to experience an issue with Acronis True Image 2020. I have a Dropbox folder which is set to online-only so it downloads files only on demand. And for some reason out of blue it started to give me dozens of notifications about downloading and opening files. When I went to Resource Monitor I saw that it's Acronis True Image doing this. It was just blanket reading everything from my Dropbox. And now I have about 20,000 files queued by Dropbox to download.
The thing is I don't have any backups in True Image which are in any way related to my Dropbox folder! It's already online, why would I want to back it up. And I don't do any backups to the folder too.
It happened again today but this time Acronis accessed these files together with Windows Defender so I was thinking what if it's Defender scanning them and Acronis is there only because its Active Protection tries to protect me from Windows Defender. But I went to Defender options and saw that last scan was 2 days ago. And I also clearly remember that when the issue happened for the first time only Acronis was accessing the files without Defender.
Why does Acronis read my personal files and how do I stop this?
