Some days, no matter how hard you try, your fingers just don’t seem to do the right thing when interacting with a computer. Other days they accurately do the right thing every time. Most days for normal people, however, your fingers do a mixture of the two. The Badger experiences the same phenomenon when playing his electric guitar, although in this case you can hear the finger trouble!
When news broke last week, see here for example, that records in the UK Police National Computer (PNC) database had been wrongly deleted, the Badger, conditioned by decades in the IT industry, immediately suspected that ‘finger trouble’ would have played a part. It nearly always does somewhere along the line when operational services have issues. It was, therefore, no surprise that the UK policing minister said ‘…down to human error, some defective code was introduced as part of that routine maintenance earlier this week and that’s resulted in a deletion of some records …’.
The minister’s words trigger many questions about what happened and why, and why recovering deleted records is more difficult than one might anticipate. The Badger was immediately drawn to three things – possible complacency in routine maintenance, testing, and mechanisms for backup and recovery. The media has concentrated on political points and ‘woe is me’ about the impact on arrests and prosecutions, but the uncomfortable truth is that events like the PNC will occasionally happen. The IT that is behind every facet of daily life is complex, handles huge amounts of data, and has been built and it is maintained by highly skilled and professional people, but there is no such thing as a guarantee of perfection. There is no immunity to finger trouble, and neither is there a crystal ball to predict ‘defective code’. The Badger therefore feels some sympathy for whoever pushed the button that deleted the PNC records.
We’ve all had finger trouble and accidentally deleted things from our computers. When it happens, it often provides a reminder that you should have backups! In today’s world the amount of data created every day is staggering and the whole concept of backup and recovery for major IT systems, and the legal rules for retaining data, is very different to that of the Badger’s formative years in IT. It’s not a surprise, therefore, that deleted PNC records cannot simply be restored from a good old-fashioned, off-site, backup tape!
Nevertheless, the PNC issue should be a reminder for each of us to take regular backups of information that you never want to lose. These days it’s cheap to do and one day you might be relieved that you did. After all, the heavenly alignment of finger trouble, defective software, and/or defective hardware can align to cause a problem at any time.
