That was the conclusion Bern jumped to, not me. Had you actually read the original post to which I was referring to you would realise he hypothesised (incorrectly) that only "paper records with cash" were processed and, as such, there was a complete and total storage failure in the part of Woolworths which "led to an inability to process any kind of transaction".
I was merely pointing out this was not the case and made no actual assumption regarding the actual configuration, which could have these transactions kept elsewhere on storage that did not fail.

And no offence but you assumption could still be wrong.
The reality is it could have been logged to failed storage but they recovered that first since that database would not need previous rows to complete the transaction (whereas credit/debit might). Furthermore you don't know for a fact that a cash transaction requires connecting to any kind of back-end system. If it does it doesn't mean that system needs storage, etc. etc. etc.
Complete storage failure was still possible.
Then how did it store card transactions?
I have transactional systems that can cache transactions before they are committed to db....
And where is this cache stored?
I wonder if they imported their computer system from China like all the clothes they sell?
Ram backed by local raid. Ie, not on the SAN.
So not a total storage failure then?
If this works so well you'd imagine they'd do it for all transactions. However, all things being equal, I'm inclined to believe that it wasn't a total storage failure but something else.
Maybe all the switches in the SAN?
But would that count as something else?
Ag shamepies let that BEE a lesson to you.
For your information. It was a hack group and nothing to do with WoolWorth's various stuff of South Africans.
