Good question. I'm interested as well.  This sounds very bizzare to me.

A few weeks ago I reported inability to restore a file (times out),
except to the backup server itself.

After a few weeks and getting several people involved, we've discovered
the cause: our router has a sensitivity to a certain sequence of=20
characters of data ... and this file had that sequence!    There is a
fix available to the router and it should be applied next week.

Thanks to all who offered suggestions!

cheers, wayne
