The Restic docs state the quoted text below regarding using SMB as a repo. Sadly, that’s exactly the scenario I had in mind (store the data on my NAS via an SMB share).
On Linux, storing the backup repository on a CIFS (SMB) share is not recommended due to compatibility issues. Either use another backend or set the environment variable GODEBUG to asyncpreemptoff=1. Refer to GitHub issue #2659 for further explanations.
I’m using the restic windows binaries, which were compiled with GO 1.13 (restic 0.9.6 compiled with go1.13.4 on windows/amd64) and how I read the issue it seems to be an GO 1.14 issue? Is it safe to use Restic with an SMB repo in my case?
