Ok, thanks.

Also, do you keep backup tapes for a while, or are they reused every
week?

It is easy to restore a set of files from the previous day's rsync
"hotcopy"?

I suggest 'du -sh' ;)

Did so :) I also issued a series of 'make -f rules/debian clean' in
compilation-environment to remove around 4GB.

Tell us how well the clean-up worked!

You may add:
/sys
/subsystems/*/sys
/tmp
/subsystems/*/tmp
/var/cache/apt/archives/*
/subsystems/apt-proxy/var/cache/apt-proxy/* (but keep .apt-proxy)

You may remove:
/subsystems/cvs/cvsroot.sv/*/dev/ (I trashed cvsroot/sv)
/savannah/tmpfs/ (Unused -> deleted)
/root/deleted-projects/*/cvsroot/dev/null (I removed those)
/initrd (is it necessary to exclude it?)

You should rename:
/savannah -> /subsystems/savannah


Also: is, for example, /subsystems/arch/home restored in the case of a
complete recovery? It's not the same as /subsystems/arch/home/*, and
the directory itself may not be restored. We would need the empty
directories (/home, /dev, /initrd, etc.) to be restored.
