Benachrichtigung beim Kopieren von Dateien ohne Eigenschaften

[Tiras]

Hallo Zusammen,

 

ich habe versucht eine Ubuntu iso von meinem Windows Client auf meinen Unraid Server zu kopieren und erhalte die nachfolgende Meldung.

Nach meiner Recherche soll diese Fehlermeldung nur dann auftreten, wenn es sich bei der Source und dem Target um unterschiedliche Dateisysteme handelt.

Da ich diese Benachrichtigung zuvor nicht erhalten habe, frage ich mich, was nun anders ist. Kann hier jemand vielleicht weiterhelfen?

Die Datei hat irgendein spezielles NTFS Attribut, das beim Kopieren auf ein SMB Ziel verloren geht. Auch weil dahinter ja eine XFS oder BTRFS formatierte Festplatte steckt. Bei einer ISO sind die egal.

 

Wenn du es genau wissen willst was verloren geht, könntest du im Explorer per rechter Maustaste auf die Spalte, die "Attribute" aktivieren:

 

Dann kopierst du die Datei auf den Unraid Server und schaust dir an welches nun fehlt.

 

Was die Buchstaben bedeuten:

C = Compressed: This is a compressed file or folder that cannot be encrypted.

D = Directory: This is the bit that differentiates between entries that describe files and those that describe subdirectories within the current directory. In theory you can convert a file to a directory by changing this bit. Of course in practice, trying to do this would result in a mess–the entry for a directory has to be in a specific format.

E = Encrypted: This is an encrypted file or folder that cannot be compressed.

H = Hidden: This one is pretty self-explanatory as well; if the file is marked hidden then under normal circumstances it is hidden from view. DOS will not display the file when you type “DIR” unless a special flag is used, as shown in the earlier example.

I = Not content indexed: This file may be indexed by search services but the contents of the file are not.

L = Reparse Points: This means it is only a LINK to another location

N = Not Indexed: The file is not included in the search services index.

O = Offline: This means it is not stored locally.  Perhaps it is in Azure File Sync so your machine only has a link to it

P = Sparse File: This makes disk space usage more efficient. When sparse file functionality is enabled, the system does not allocate hard disk drive space to a file except in regions where it contains nonzero data. When a write operation is attempted where a large amount of the data in the buffer is zeros, the zeros are not written to the file. Instead, the file system creates an internal list containing the locations of the zeros in the file, and this list is consulted during all read operations.  You might find THIS and THIS interesting.

R = Read-Only: Most software, when seeing a file marked read-only, will refuse to delete or modify it. This is pretty straight-forward. For example, DOS will say “Access denied” if you try to delete a read-only file. On the other hand, Windows Explorer will happily munch it. Some will choose the middle ground: they will let you modify or delete the file, but only after asking for confirmation.

S = System: This flag is used to tag important files that are used by the system and should not be altered or removed from the disk. In essence, this is like a “more serious” read-only flag and is for the most part treated in this manner. It is also a “super-hidden” attribute. Even if you enable “Show hidden files”, system files will not be displayed. (You can display them by disabling “Hide protected operating system files.”)

T = Temporary: The file is marked as non-permanent.  Many pieces of software (like backup software) will ignore files with the T attribute.
