data recovery and rsync, among other things

[Dan Stromberg]

I've been trying to extract some of my clients' data from a flakey lustre
filesystem, and as a result, took some time to write up a page about
pulling data out of a semi-crashy filesystem.  The page includes a variety
of ways of doing so, those ways including but not being limited to
rsync and a program I wrote called try-copying-up-to-n-times that was
inspired to some extent by rsync.

I hope someone will find it useful:
