Backup a VeraCrypt (TrueCrypt) volume on Windows gives an error

When doing a backup of a VeraCrypt drive on Windows I get the read-error: error: Open: open \\?\S:\System Volume Information:

Backup command: restic.exe backup --iexclude="s:\temp" "s:"

The backup seems to succeed and the error seems to come in the middle of the backup, not in the beginning nor the end. Should I be worried?

Full status:

repository 4cf59dcd opened (repository version 2) successfully, password is correct
no parent snapshot found, will read all files
error: Open: open \\?\S:\System Volume Information: Access is denied.

I don’t think that this is veracrypt related. The system volume folder is not readable on a running system in anyway.
I would say you can ignore the error, or even more elegant, exclude the folder from your backup.


I didn’t even consider it to be a real folder, but of course it it! I just exclude it.
I just unconsciously thought of it to be something deeper in the filesystem and not a folder.
I should just have done a “dir /a-”
