Hi,

Output of restic version

restic 0.9.6 compiled with go1.13.4 on windows/amd64
I use restic on Microsoft Windows 10 (1903).
I run restic on command line with administrator access.

How did you run restic exactly?

restic -r D:\restic --verbose backup C:\ProgramData\restic\shadow\C

C:\restic>restic -r D:\restic -f --verbose backup C:\ProgramData\restic\shadow\C

open repository
enter password for repository:
repository cacd2f5e opened successfully, password is correct
lock repository
load index files
start scan on [C:\ProgramData\restic\shadow\C]
start backup on [C:\ProgramData\restic\shadow\C]
scan finished in 0.255s: 0 files, 0 B
error: NodeFromFileInfo: Readlink: readlink \\?\C:\ProgramData\restic\shadow\C: The parameter is incorrect.
 
Files:           0 new,     0 changed,     0 unmodified
Dirs:            4 new,     0 changed,     0 unmodified
Data Blobs:      0 new
Tree Blobs:      0 new

processed 0 files, 0 B in 0:00

But, if I backup a subfolder it works:

C:\restic>restic -r D:\restic --verbose backup C:\ProgramData\restic\shadow\C\tmp

open repository
enter password for repository:
repository cacd2f5e opened successfully, password is correct
lock repository
load index files
start scan on [C:\ProgramData\restic\shadow\C\tmp]
start backup on [C:\ProgramData\restic\shadow\C\tmp]
scan finished in 0.268s: 1 files, 213 B
 
Files:           1 new,     0 changed,     0 unmodified

Data Blobs:      1 new

What backend/server/service did you use to store the repository?

Local

Expected behavior

Backup of the files.

Actual behavior

Backup end with no file but snapshot created.

Steps to reproduce the behavior

1/ Init a new repository
2/ Do a Shadow Copy of C:
3/ Create a symlink to allow access of this Shadow Copy
4/ Start backup of the root of symlink.
PS: If I try to backup a subfolder it works (for example : restic -r D:\restic --verbose backup C:\ProgramData\restic\shadow\C\tmp instead of restic -r D:\restic --verbose backup C:\ProgramData\restic\shadow\C).

Do you have any idea what may have caused this?

No :(
Maybe me but I don't understand.

Do you have an idea how to solve the issue?

No :(

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

Yes :)
