Do these error messages indicate a problem with my backup?
Please see below, the beginning and ending of a recent log file emailed to me from Acronis True Image 2020 after a recent file backup of my C: and D: disks. There are some embedded "error" messages but the final lines seem to indicate the backup was successful. How should I interpret this log? Do I trust this backup file?

Peter, the error messages do indicate that some parts of your backup source data were not able to be captured in the backup image, but otherwise the backup was successful.
Error 0x40011: Link target was not backed up.
This error would suggest that you are including files that are not physically on the source drive, i.e. such as those on OneDrive when using Files on Demand etc which use reparse points as markers for the linked files in the cloud service.

According to https://kb.acronis.com/content/46585 this is expected behavior if you are backing up something with symbolic links or junction points. Based on other messages in the log, the "problem" was a link in iNetCache. On my computer, there is a link in iNetCache to "Content.ie5".
You certainly don't need need that backed up.
I wonder why I don't see that error in my backups.

So are these more like warnings rather than errors? Is this backup valid, meaning that should I expect that this backup is capable of being used to restore the files I backed up, if I need to restore one, or more, or all the file?

The path shown in the trace under the Link target not backed up message is the destination of a symbolic link or junction. This can happen when something included in your backup selection is actually a link to something outside the backup selection.
Windows has quite a few of these links set up. If you want to see them, under a command prompts enter the command:
dir /al /s c:\
Looking at your log, the first error (not highlighted) shows C:\ProgramData as the path. On my system, I can see a link set up by Windows from C:\Users\AllUsers to C:\ProgramData. It looks like C:\Users is included in your backup task, but C:\ProgramData is not.
By the way, to fully see it, I had to unhide system files in Explorer and then I could see C:\Users\AllUsers and when I clicked on it, it went to C:\ProgramData.
In summary, the message is normal and you should be fine. Error... Warning... who decides?
