‘Cloud computing’, where the data is stored safely away from the user’s device is an old idea.
Until the 1990’s most office computers were ‘dummy terminals’: a keyboard and monitor linked to a separate server (usually in the IT dept.) where all the data was stored, on what we now call the shared hard drive.
That all changed with the arrival of ‘personal computers’ or PCs. Users began storing data on the local hard drive of their computer. The benefits were obvious. You no longer needed to be connected to the office server so you could update your sales figures from home or on the road.
Then at the next sales meeting, all the attendees would have the same group spreadsheet… only slightly different versions, as not everyone had undertaken the tedious task of copying their latest figures on their personal hard drives to the spreadsheet on the shared drive.
Next the data on your home PC is corrupted or your laptop is stolen. All the latest performance draining virus protection you installed won’t bring back the data you failed to back up. Hmmm.
