Problem description / Steps to reproduce

Edit Office files (MSWord, Excel, Powerpoint) while running a backup.

Expected behavior

Up to now, I did not notice errors related to the files that I was working on during backups.
I expect that the backup can run in the background without interfering with the work I do.

Actual behavior

I was working with a Powerpoint file while the backup was running.
The temporary file that Powerpoint creates caused the following error:

restic.exe : error: incomplete metadata for Home\@Work\02-Areas\Teaching\Python-DSBA\slides\~$Python-1.pptx: multiple
errors occurred: [get named security info failed with: The system cannot find the file specified.; get EA failed while
opening file handle for path Home\@Work\02-Areas\Teaching\Python-DSBA\slides\~$Python-1.pptx, with: The system cannot
find the file specified.]

Do you have any idea what may have caused this?

This file has been removed when I closed Powerpoint during the backup.

Did restic help you today? Did it make you happy in any way?

Definitely yes : I rely on restic for my home computers backups for a few years now.
It is by far the best tool that I could find for this job.
