Ricky, you bring up an interesting idea.
We aren’t going to resolve it here, but could the major tech companies develop and agree on a standardized “archive” file format and perhaps even a device/media standard for storing this data too that could allow for permanent and reliable archival of critical data?
From the posts in this topic, it seems clear that many of us have concerns about this area of our digital lives as we move more and more toward a truly paperless world!
Right now I have a convoluted array of solutions to try to insure data integrity. I have on-site mechanical hard disks and optical M-DISCS as well as my NAS array, basically duplicate sync services using Dropbox and iCloud and topped off with BackBlaze cloud backup and a rotating system of hard drives with my most recent bootable clone and Time Machine data that are swapped at my bank safe deposit box monthly.
This is clearly overkill and requires a lot of effort to maintain, however I have lost critical data in the past and will not risk that happening again. Nothing is absolutely “bulletproof”, but I have gone above and beyond what any book on backup strategies has suggested - probably at least by a factor of two!
But it would be of incredible value to me to have a system that could replace most of this physical/on-site stuff with a single, highly reliable format and media.
I do have computer literate executor/trustees for our will/trust, however even so it is not an easy task to have to look through the various data storage locations to make sure they have the most current version of a particular file. Then, if for some reason that file were damaged, having to go through a half a dozen backup or synced sources to find the most current backup is also a pain.
However Dropbox and BackBlaze both have file versioning, and so does my NAS as well as Time Machine. Since those are all automated processes running in real time, there are several options for a good copy of a file that should be close to current.
Nevertheless, this is all overwhelming - even to me. Just writing this post has been exhausting (as it probably has been reading it for YOU)!
In summary…THERE HAS TO BE A BETTER WAY that still protects data integrity!
