They've been promising them for ages - I'll believe it when I see it. > The best approach to backing up is usually to say no.

With a statement like that, it's pretty obvious you haven't worked in the financial, insurance or government industries. Backups of financial data can be legally required in court, showing the ORIGINAL data, for up to 15 years after the fact. Insurance is worse, I believe. And some government departments - police, RTA, courts etc - worse still. Saying NO to backups is suicide - certainly for any SysAdmin's career, usually for the company involved as well. Sooner or later, some form of failure comes back to bite you in the arse. > Next best approach is to only do it incrementally, forever. I.e. use > rsync to remote copy.

Believe it or not, despite this being a Unix users list, a good percentage of the commercial world does NOT run *nix. > Whatever you do, compare the cost of backing up versus the probability > of losing the data times the cost of losing the data. Is the complete and total extinction of the company you work for justification enough to backup? Thanks for your advice - personally and professionally, I'll stick to my backup regeim.
