Can you send the patches you're proposing?

I think Stefan's point about the system view overhead is related to 1)
the inherent overhead in the XML encoding, 2) the base64-encoding of
binaries, and 3) the hierarchical view of the content. 1 and 2 are
pretty well handled by zip compression, but 3 requires the backup tool
to walk the tree hierarchy (in comparison to just linearly dumping all
the node states) when doing the backup.

Using the system view has its benefits and drawbacks, and although I
wouldn't originally have used it for the backup tool, I think Nicolas
has a good case for going with the system view, at least for a first
version of the backup tool. The hard part in that decision is figuring
out the way to do the restore...
