It took a moment to think about it, but just to be certain, would "recovering a file" from this entail the following:

   cat backup* | gunzip | tar -x <files-to-restore>

I'm still a little fuzzy on whether or not some "temporary" file might be involved (which might run into the 4GB filesize limit)  or is that the nature of "pipes" in that these programs actually work "concurrently" so that the number of bytes "in the queue" remains trivially small?
