On a Windows 7 PC running Paragon Backup Version 18.104.22.16881 I'm trying to run a "Files Backup". The operation seems to start, and then it just hangs while Estimating. The estimating does get to a certain point and just stops midway. The file it gets stuck at doesn't seem to matter. I then can't end the backup process (using the "Cancel" option does nothing, I either have to kill the process or reboot the system). First of all is there no option available to turn the "Estimation" off? In my point of view that isn't necessary and just uses more time. I can't find any such option in the interface though. Second, how can I get a file backup to run through? Edit: Things I've noticed in the meantime that may or may not be relevant: I checked the windows eventlog and saw an error 8194 with the Volume shadow service. I checked the services and there it is started. Also this error happens long before the backup gets stuck, and the files where it gets stuck aren't open, so I don't really think that this has anything to do with the issue, but I thought I'd mention it anyway. Thanks for any help.
