Thanks James for a non-hifalutin, direct, clear explanation of your method.
It is what I surmised, and is clearly the most logical, cost-effective, and safe way of storing all those records for the required 7-10 years.
How do you recommend storage of the charts? My whole database and ImportedItems will fit on a 64G flash drive, but will that be readable in 7-10 years?
Would an SSD be better for storage? Or even a standard hard drive? What can just sit on a shelf and not lose data?
What has the best chance of long term survival?
The Googlable gurus are not totally clear or convincing about long term storage.
