1. Redundant copies.

2. Sometimes your filesystems are larger than the largest drives.
   For example, I'm currently seting up backups for a 24TB filesystem
   where a network-based DR is not feasible (the average rate of
   churn exceeds the available network bandwidth).  Good luck trying
   to find drives that big.

I had a sense of deja vu the other day; I was taken back to the time
when I first ran into a filesystem that was larger than the size
of a backup tape and the software I was using at the time (Amanda)
had the assumption that a single filesystem was smaller than a single
tape.  (I understand they fixed that assumption shortly thereafter,
but I had already moved on to another product.)

For the record, my favourite product is Bacula.
