Ever given any thought to breaking those filesystem up? We have similar
issue w/ some of our NAS volumes and are trying to push back to get them
smaller...

The full backups are sort of spacing themselves out (my 2 primary file
servers have a total of about 75 file system). However, your point is
valid, I'll work on spreading the full policies out over the 4 weeks.
As for design rule #2, I have some multi-terabyte file systems that take
longer than 24 hours to back up. In fact, depending on what's happening
with research, users can generate more than a terabyte in a day on some
of them, which means incremental backups of those file systems can take
more than 24 hours.

Given that we're seeing explosive growth in data storage demands, I'll
take all the drives I can get my hands on.
However, we're trying to get budget to add disk staging, which should
reduce the number of drives needed.
