Force detailed log of all backup files and missing files

IF you are doing the standard system calls for enumeration, you should not care what path or files the filesystem returns.

Duplicati is written in C# and uses the standard enumeration and access. It is technically possible to use other Windows API calls, but the ones in C# are the ones the .NET team (mostly Microsoft) considers the “best ones”.

I agree with your statement, it should not matter, but there are always details.

@Richard_DeVito_Jr

IS THERE a way to force duplicati to do a FULL backup each time?

Not really, it is not designed for that. It makes differential backups, only unknown stuff, but I don’t think that detail is relevant for your case.

The source volume is the Q: volume. It is a mapped drive to a netware volume.

This is likely the problem. Duplicati expects a local file system as the source. It should in principle work with a mounted folder, but it looks like there is some small quirk here.

I think this is the same issue we discussed in “Failed backup but why”, but there it was the destination that was a NetWare folder, and here it is the source?

I have found a new article that mentions the same problem and it states that it is an issue with NetWare not supporting long paths:

• https://s3.amazonaws.com/asigra-documentation/Help/DS-Client%20Help/index.html#page/DS-Client_Help/Backup__2f_Restore_of_Novell_NetWare_files_from_a.html
  

Based on that, I think there is some issue with the paths, where C#/.NET/Duplicati transforms the paths from old-style C:\Folder\File to the newer UNC style \\?\C:\Folder\File and this does not work with the NetWare drivers.

Another comment here says anything larger than 5MB seems to fail:

And I saw a recommendation to update the Novel Client, if that is possible.
