Post Windows recovery problem
Hi all,

I use fsarchiver and ntfs-3g to recovery my Windows Embedded 8 standard(WE8S) system.

I use these steps to backup and recovery my WE8S image:

1. Install WE8S to the device
2. Use compact.exe to compress WE8S system.
3. Run sysprep.exe to initialize WE8S system.
4. Backup WE8S image by fsarchiver 6.10 and ntfs-3g 2012.1.15
5. Recovery WE8S image to other devices by fsarchiver 6.10 and ntfs-3g 2012.1.15
6. After recovery image, boot the system.
7. The system would initialize failed or there are some files corrupted on the system.

During backup image, there are many error messages [errno=31, Too many links].
During recovery image, there are many error messages [errno=2, No such file or directory].

I attached my error logs,and I also test many versions of ntfs-3g(2012.1.15, 2013.1.13, 2013.1.13AR4), but the result is same.

ntfs-3g-2012.1.15 doesn't have [errno=31, Too many links] error, but the system have file corrupted problem.
ntfs-3g-2013.1.13 and ntfs-3g-2013.1.13AR4 have [errno=31, Too many links] error, and the system also have file corrupted problem.

After recovery image, I also run chkdsk on the system.

Chkdsk shows these message:
Found an unneeded link ($FILE_NAME: "igdfcl64.dll") in index "$I30" of directory "\Windows\System32 <0x1,0x4bd3>"
... repaired online.
Found an unneeded link ($FILE_NAME: "igdfcl32.dll") in index "$I30" of directory "\Windows\SysWOW64 <0x1,0x80d7>"
... repaired online.
Found an unneeded link ($FILE_NAME: "ieframe.dll") in index "$I30" of directory "\Windows\WinSxS\amd64_microsoft-windows-ieframe_31bf3856ad364e35_10.0.9200.20534_none_ed0c3dc1062db9ad <0x1,0x97d0>"
... repaired online.
Found an unneeded link ($FILE_NAME: "wmp.dll") in index "$I30" of directory "\Windows\WinSxS\amd64_microsoft-windows-mediaplayer-core_31bf3856ad364e35_6.2.9200.16384_none_64336a83d8ddef8c <0x1,0x9985>"
.
.
.


It seems that index "$I30" have many unneeded link.
Could anyone help me to solve this problem?

Hi,

Getting the short name through extended attributes for files which have several names has been deprecated. This was needed because the system interface used by fuse cannot reliably identify the directory used to designate the file.

In ntfs-3g-2012.1.15 getting short names for files with several names was still allowed... but this sometimes lead to short names being associated to a wrong directory. This is why this possibility has since been deprecated.

This depends on how fsarchiver reacts on errno 31. If it just ignores the short name when the error occurs and goes on processing the other names, these short names will just be missing from the restored file system, and this will be a problem only if you use an old software which requires short names.

However chkdsk found discrepancies between files and directories, and the wording "unneeded" tends to mean it deletes the names from directories instead of inserting an extra name to the file. This is bad.

Note : for saving/restoring a Windows 8 system partition (which has a lot of hard links), ntfsclone is more likely to do the job. Also wimlib should be able to save/restore short names on files with several names : http://sourceforge.net/projects/wimlib/

Regards

Jean-Pierre
