RE: My client backup is populating directory names, but not files

[Martinez, Michael - CSREES/ISTM]

Okay I've narrowed down the problem. 

Orginally I was having problems restoring data (checksum errors; missing
files). I was using "dump", so I switched to gnutar.

Gnutar worked better, in that I was able to restore files. But when I went
and did a diff or a cmp, many of the restored files do not match their
originals: random byte-replacement; eg. the letter "g" intead of "e"; or the
character of "-" instead of "/"; and so on.

I stuck in a new cleaning tape; ran it through; stuck in a brand new tape;
and did a direct tar to tape of one of my filesystems. I restored it back -
same problem; lack of integrity in the data. Random bytes not pulling over
