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.
