[Bug 1290563] Re: tar backup and restore produces corrupt data

[Robert Nemeth]

I get the same error using cp - this is very very bad..... an example of
the resulting error is this:

this is the ls -lR output from the root of the drive:

./AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/G300stuff/full backup of
OS/App2SD/AcerLaptop/2gbSD/ebay/Pinnacle/Program Files (x86)/.......

As you can see it is totally screwed up.  This is about as serious a bug
as it gets, as read works, but write is as good as useless.

Title:
  tar backup and restore produces corrupt data

Status in “xfsprogs” package in Ubuntu:
  New

Bug description:
  I'm using xfsprogs 3.1.9ubuntu1 on 13.10.

  I tar'd a disk partition from a connected drive taken from a Buffalo
  Linkstation using

  tar pcvf /home/.../xfs.tar .  (whilst on the relevant dir)

  The tar worked fine (as far as I could tell), but when I restored this
  to a new drives xfs partition, the resulting restore was totally
  messed up.  It 'looked' ok from an ls of the root, but several folders
  down and directories were listed as files, and a fourth level
  directory listed the second level directory as it's contents.  It is
  totally unusable.
