Original Poster Here: Query? - There are "Ultra-High Grade" Discs made with Gold (to resist corrosion), High Grade Plastics to resist scratches and etc, and with the use of 'higher' stability Dyes (?) all put together with high quality construction processes in their production. The prices are very high for these discs compared to the el-cheapo spindles on sale every week at the BigBox stores. eg: a hundred discs are 150 bucks versus 10 bucks. The 'Tested' theoretical life of these gold disks are 300yrs versus 100yrs for 'normal' High Grade disks. In my non-digital photo printing life there was an outfit doing printing paper and storage methods testing for expected life spans and such who's AUTHORITY and METHODS were exceptionally well regarded. Where is an organization like this for storage mediums. One (or more) has to exist but where do I find it?
Query: Where is the 'glaring hole' in my data backup plan for these image files? My 'intended' burning methodologies are to burn very slowly (1x if possible) which in theory and personal experience gives very nice burns with excellent readability in multiple drives. Multiple data integrity tests using multiple drives to verify the burns contents is intended. These methods combined with numerous multiple copies of the entire data set seems like it would give a LOT of data security. With the 'Science' & 'Experience' I have and know about - My intended use of 'Ultra-Grade' materials and 'Ultra-Careful' methods to create at least 10 pristine duplicate Disc Sets that will be stored 'as sets', in a durable container, with each disc in individual jewel cases, and a Case that promotes vertical storage, should be an Ass Kicking method to ensure that say 5yrs from now a 'Pristine' copy of this data set exists to be replicated onto whatever is the best method to use 5yrs from now. I would also provide to each 'set holder' a User Copy to use and abuse as they access and view the images. I personally DON'T see the hole in this plan. It will be time and labor intensive to implement this plan, but I have nothing but time on my hands and the 'labor' is labor I can do with my physical limitations. I am 100% - hands on - personally aware of the perils Data burned on Optical Media present. I'm currently dealing with a large cd binder of cd-r's that a roof leak gunked up in the family office. Some of these discs are surface ruined from previous rough handling, some are substrate damaged/corrossion, and some have the reflective layer flaking off the topside. I also note that -absent mildew/moisture- that the 5yr old Name Brand disks that were clean read perfectly. I'm thinking well made disc's that are well stored (some in safety deposit boxes - I hope) are going to be there for us to use for many many years.
