Hi David,

good to read that I'm not alone :).

I don't care that much for live data. To loose a few minutes or even a
few days isn't fun, but bearable. Backups and archives can contain a
full life.

Unfortunately integrity checks are way to often a PITA :(.

My current strategy is an obsessional neurosis. It's a little bit more a
psychopathological workaround, than a computer technical attempt.

I have got tons of backups (unfortunately not stored in different
locations, just on different drives) and from time to time I restore
backups or archives using a sandbox, just for testing purpose.

Regards,
Ralf
