I beg to differ. I customarily use dump to backup everything in my
workstation (both data and programs), before doiong any major change
like an upgrade of kernel & userland after a buildworld/buildkernel
run. I check this by restoring to a spare partition, to make sure
that if anything goes wrong I can roll back to a known, working state
of everything, and then do the dangerous upgrade stuff.
This seems to work on both data and programs. In fact, programs being
mostly static, are a lot easier to grab in a well-known state, as
opposed to randomly[1] changing data, like database tables or log
files.
[1] "Randomly" as far as dump is concerned, which doesn't need to know
what that data represents or how it's accessed or changed by their
respective programs.
