rsync - Aug 2012 - [Bug 9103] New: ext4 creation timestamp

https://bugzilla.samba.org/show_bug.cgi?id=9103

           Summary: ext4 creation timestamp
           Product: rsync
           Version: 3.1.0
          Platform: x64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: enda_k2 at yahoo.com
         QAContact: rsync-qa at samba.org


Is there a way to backup (copy) data with their time creation stamps from a
NTFS filesystem to a ext4 filesystem?

http://computer-forensics.sans.org/blog/2011/03/14/digital-forensics-understanding-ext4-part-2-timestamps:
There's a "crtime" (create time) timestamp in the debugfs stat
output. Yes,
EXT4 finally supports a "born on" time (btime) like NTFS, giving the
timestamp
for when the file was created within the disk volume.

This hasn't been implemented, but sounds like something that woulnd't be
that
hard to code up into the the crtime patch.

Hi Wayne, I'd like to thank you for picking this up.  What's the current
status?  I would also love to see Samba preserving NTFS file creation
timestamps ? many people have gathered files over the years, and now want to
move to a Linux-based NAS.  To me, these file creation timestamps are very
important.  (File modification timestamps work as expected.)

If someone would like to research how code checks a crtime, coming up with a
patch that changes the existing crtime.diff patch would be appreciated (or even
just reporting the result of the research).  Otherwise I will look into it at
some point in the future.
