I upgraded one machine to this, a Windows server from the previous canary (2.0.3.14), and now I get a warning that snapshots are failing:

```
2018-11-13 13:23:38 +01 - [Warning-Duplicati.Library.Main.Operation.BackupHandler-SnapshotFailed]: Failed to create a snapshot: System.NullReferenceException: Object reference not set to an instance of an object.

```

I run it as a service, Local System, usn is “on” and snapshots are set to “on” and none of the writers report a problem and nothing is logged in the Windows event logs. Disabling usn makes no difference, I have also rebooted.

If you downgrade to 2.0.3.14 do the snapshots work again?

@kenkendk, by removing OneDrive v1 have we just orphaned any v1 specific settings such that users migrating away for it can’t get to them in the GUI for removal anymore?

Spooky, that just went through my mind, and yes going back to 2.0.3.14 (re-ran installer then had to run a repair as the main exe had vanished and service would not start), snapshot is fine.

Can see this here too after running a backup on 2.0.4.2, installing upgrade, manual service restart, try again. Changing snapshot-policy to off avoids it, but with it on, which is what I want, profiling log shows the following:

Heh - I can think of some former co-workers that could benefit from a little mind sharing… 😉

If you feel game, would you consider updating to .4.1 or .4.2 to see it we can pin down where the issue came in?

Edit: scratch that test - it sounds like @ts678 can confirm it worked fine in 2.0.4.2.

So it’s failing when CLOSING the snapshot?

Odd - I don’t know where that happens in the backup process but does that backup appear in your restore list?

Yes, and confirmed by doing another one with --snapshot-policy=On (and getting the Warning). In spite of the timed log I posted earlier, I also observed visually that I no longer got the 50-or-so-second delay VSS usually throws into my starting phase. Looking at announce and code, I see wide [changes](https://github.com/duplicati/duplicati/pull/3456) got done in path handling.

Yes, a lot of code was changed. Technically it should work as before, but I’m not surprised if something broke. I will look into it.

Edit: Can you open an issue on github? I will handle the problem from there then, so I can also refer to the issue number for upcoming commits.

[2.0.4.3 canary --snapshot-policy Windows VSS System.NullReferenceException regression #3494](https://github.com/duplicati/duplicati/issues/3494) is GitHub’s version of this (with some additional testing). Thanks for your code @verhoek, and looking at apparent bug.

Possible regression (unless it’s an undocumented feature) from 2.0.4.2 is that GUI Commandline on a backup with a passphrase no longer includes job’s passphrase, and fails (e.g. on backup) as below. 2.0.4.4 does too.

```
ErrorID: PassphraseChangeNotSupported
You have attempted to change a passphrase to an existing backup, which is not supported. Please configure a new clean backup if you want to change the passphrase.
Return code: 100

```

Workaround is to manually add the passphrase option, or export as commandline for command prompt use.

[added checkbox to allow exporting backup passwords #3467](https://github.com/duplicati/duplicati/pull/3467)  
[hide encryption passphrase when exporting to commandline #3474](https://github.com/duplicati/duplicati/pull/3474)  
[Exporting a backup configuration should not export passwords by default #3466](https://github.com/duplicati/duplicati/issues/3466)

Maybe @Pectojin can say whether the GUI Commandline was supposed to be impacted. It **IS** more secure because previously the field of asterisks hiding the passphrase could be bypassed by clicking “Edit as text”.

That’s definitely regression. It was never intended to affect the commandline UI 🙂
