Wow Ryan - I know this is really late................
But it looks to me like your database was backed up in chunks - i.e. the backup was spanned among several files....stdin.001, stdin.002, etc.
If this is the case then it looks like your backup is corrupt - or at least the first file of the backup is corrupt and hence, unreadable.
Sorry for taking so long...........I'm not around much anymore - life tends to get in the way.
So this probably didn't help you at all.
Which reminds me why I want to start working on a beowulf-on-a-backplane design: I want to be the one to write the program called "clusterfsck."
