Shadow Copy Storage
I've been reading through that wonderful best-seller, the Event Log, now that the machine is back to working more or less as it should after last week's joy of "all folders locked, and you're not allowed in there, peasant!"
There is some wondrous stuff in the Event Log, showing just how abstruse Windows 7 can be when you get into the realms of who owns which drive/partition/folder and who can do what to it - after it's all gone wrong.
I've sorted most of that, and it's down to 3 or 4 "Red errors" a day now. Some of those are of the "where's my Jepp datacard writer gone?" type - the device is back in its box on the shelf till next month. No issue.
But occasionally it will spawn a load along the lines of "shadow copy storage is full" or "cannot be accessed" or "is trying to shadow itself and has a headache". I think shadow copy storage is a sort of "roll back file changes" facility, but ...
question for the wise of PPRuNe...
... should I bother to use shadow copy storage, or is it a waste of space and time?
I've found where to switch it on and off.
