I've been playing catch up this week due to data loss.
An upgrade of the OS went off as scheduled, but it unfortunately erased about two years of projects that were stored on that computer. When the system was added to the shared storage array, the projects were still being stored locally. Pilot error that didn't kick in for about 18 months.
The primary effect was losing the bin data on a half dozen projects that are in production, but it will also mean that if asked to make changed or simply recreate an old project I will be starting from scratch.
In the old CMX days there would have been pages of notes and perhaps a paper EDL to work from on the rebuild, but not anymore. Digital does have drawbacks, and I'm living them this week.
