Our incrementals take about 2 hours (both backends are done at the same
time). Our fulls take an entire day, but we only do fulls once a month.
I'm hoping that using smaller partitions will let us do backups in shorter
times, assuming we stay with tape-backups.

I'm curious what storage hardware you are exploring. What are you using
now for your 7 backends?
