"I think you'll find that there is no garantuee as to the safety of your data in that 'well looked after, heavily DR supported system' of yours. You see, back-ups cost money. Things that cost money, especially things that don't have immediately apparent consequences (like not making back-ups) have an annoying tendency to get cut."
err, any SAAS seller is going to be out of business fairly fast if they dont have decent DR and real time off site data backup
"Local database, with redundancy, encrypted and off-site back-ups is still the only reasonably secure way to go."
Depends on your rate of data flow, even a loss of 24 hours between backup and failure can cripple a business.
We do SAAS for the management of Yoga/Pilates/FItness facilities around the world, none of those sectors are renowned for there IT capabilities, data backups or budget for there own hardware, servers, offsite back up etc etc. I have had people in tears on the phone who didnt bother with back ups and then had there comp stolen or destroyed, doesnt happen now.
"And anybody who runs a database and fails to back-up regularly deserves to be shot anyways."
On that we agree.
