Uh huh. My taxes at work ;-)

You can secure your data without full journalising batch processes. I'll
agree that real time should be journalised, so that recovery time is
minimised.

? You go back further to a working version and roll that forward. You DO
keep multiple backups, don't you? If data's critical, you should have
copies of the backup anyway - one copy onsite, one offsite at the very
least.

Yeah. I didn't know they couldn't do it, but it's no surprise. They're
hackers.
