## Environment info
- **Duplicati version**: 2.0.6.3_beta_2021-06-17
- **Operating system**: Win10
- **Backend**: SMB via TrueNAS-12.0-U5.1
## Description
A backup creates new files that does not have any visible access time causing the backend validation part to fail.
The backup job is considered a fail and no logs are saved via the GUI.
The email report contains:
```
Failed: Not a valid Win32 FileTime.
Parameter name: fileTime
Details: System.ArgumentOutOfRangeException: Not a valid Win32 FileTime.

I have other backup jobs to this same backend that is running with issue.
## Steps to reproduce
1. Run backup
- **Actual result**:
Backup failure
- **Expected result**:
Successful backup
## Screenshots
## Debug log
The reason for the invalid timestamp is somewhat of a mystery, I believe. Duplicati is not responsible for it, but a fix for Duplicati has been proposed so it will ignore these invalid timestamps.

any fix yet ? on what file we have to modify in windows ?
Looks like the fix has been merged, so it will be available in the next Canary release.
In the meantime, use touch or a similar command to fix the timestamps. See the post I linked to above for more information.
