    Massive irretrievable data loss...

    Malcolm Tucker has some words for this

    WTF is the backup?

    Who is this outsourced to ? Anyone know?

    Why there is even a possibility to delete any records in such database?

      They should have asked a data scientist like me. Clearly they have been mining the data lake. This was bound to happen when one of the mines exploded.

      Since they followed the advice from the other thread, they only had one lake, there was no backup.

      So, unfortunate, but they were following best practice according to CUK.

          It's not a database, it's a federated group of databases spread over multiple server farms. All you have to do is delete one of the ones that holds the key information that links them together.

          And looking at current cloud technology and operations, backup appears to be an outmoded concept.

          It seems they are trying to recover it all. I suspect that means rebuilding the database that was "damaged" from other sources and then rebuilding the overall mapping.

          That said, as an ex-service management guy, the whole thing is f***ing appallingly amateurish.

            Not even Federales in Mexico (with double the population) got so much crime to require so much hardware

              Are there databases involved? ?

              I was under the impression it was a spreadsheet in sharepoint that got deleted by accident.

                Um, no. Only by people who don't know what they are doing.

                Granted you no longer need to worry about hardware failure (as redundancy is built into the service you are buying) but you should be doing snapshots prior to major operations.

                  Sounds like a microservices type of issue where they are linking different datasets for things like DNA and fingerprints and a cascade delete went through them all.

                  It would seem that in lieu of a transaction log to roll back they would have queues between the datasets to provide loose coupling and resilience that could allow similar undo capability by rolling back the queue actions. Presuming audit requirements are in place to keep a log of all actions especially updates and deletes so there is always a trail, and worse case they manually re-enter the trail of deletions.
                  Maybe tomorrow, I'll want to settle down. Until tomorrow, I'll just keep moving on.

                    Don't tell me, let me guess - It's all in Excel spreadsheets, right? These amateurs seem to have a thing about Excel

                    I assumed it was an "accidental on purpose" deletion, e.g. to lose evidence that might have lead to more convictions and increased the prison population, or to reduce the number of sex trafficking and grooming convictions among the vibrant community. But if they are genuinely scrabbling around trying to recover the data then maybe it was an actual mistake.
