I looked into recovering files for a 550 before. The XFS filesystem has
sadly, never been designed to make this possible. It is a logn story, and i
tried a lot of tools for the customer at that time, but the bottom line is
that it is close to impossible with xfs to do any recovery, especialy
automated ones.

this is what de faq from the xfs developers has to say about it;

[quote]
Q: Does the filesystem have a undelete function?

There is no undelete in XFS, in fact once you delete something, the chances
are the space it used to occupy is the first thing reused. Undelete is
really something you have to design in from the start. Getting anything back
after a accidental rm -rf is near to impossible.
