Windows NTFS Alternate Data Streams are not supported through Samba
Windows NTFS Alternate Data Streams are not supported on Ext2/Ext3 file systems and consequently neither on HSM file systems. Therefore, they cannot be migrated to FSE media.
Windows-specific limitations
Unsupported Windows services and file system features
FSE implementation does not operate in some Windows environment configurations and does not support some Windows services and NTFS file system features:
•Microsoft Cluster Server environment is not supported.
•Windows Terminal Server or Citrix Metaframe interoperability is not supported.
•Removable Storage Manager (RSM) interoperability is not supported. RSM must be disabled to enable normal FSE implementation operation.
•Remote Storage Service (RSS) interoperability is not supported.
RSS must be disabled to enable normal FSE implementation operation.
•NFS server products running on top of the FSE implementation are not supported.
•Distributed File System (DFS) integration with the FSE implementation is not supported.
•Encryption File System (EFS) and HSM file system integration is not supported. EFS encrypted files should not reside on the HSM file system.
•HSM file system does not support compressed files.
•Operating system components and installed applications cannot reside on the HSM file system (page file, system restore data, temporary files, binaries, and
•Junction points, resource forks, and reparse points cannot reside on the HSM file system.
•FSE implementation interoperability with File Replication Services is neither tested nor certified.
Unsupported third-party software
FSE cannot be integrated with certain
•VERITAS Storage Exec (former name: VERITAS StorageCentral)
•Microsoft iSCSI Software Initiator
•Microsoft Firewall Client 2004
Move operations to overwrite existing files on HSM file system are denied
FSE prevents move operations to overwrite existing files on the HSM file system which could lead to missing delete events. Attempts to move to overwrite an existing file is denied and the move operation fails. For a move operation to succeed, remove the target file or directory first.
Recycle Bin must be disabled on FSE implementation
FSE does not support the Recycle Bin for HSM file systems. The Recycle Bin must be disabled on a consolidated FSE implementation and FSE clients for all HSM file system volumes since the files cannot be restored back to these volumes. Note that the disabling is performed automatically during the installation of FSE, and no action from the FSE administrator is required.
To disable the Recycle Bin, change the following registry key to the suggested value:
\HKEY_LOCAL_MACHINE
\SOFTWARE
\Microsoft
\Windows
\CurrentVersion
