There are quite a few reasons in an EDP environment for restoring
files.  For example, before a large unreversible process, it is
common to dump the entire database partition so it can be restored
if the process is found to have completed incorrectly.  This is
very common for such operations as payroll, monthly account closing,
quarterly stuff, etc.

The answer to questions like "How often do you do X" often come
down to "Often enough that we can't stand it any longer."
