I'm about to archive important photos onto 10x 25GB M-Discs. I would appreciate it if my archival strategy could be sanity checked before I burn through $50 of disks.
My plan to to manually break up the photos into 5x ~20GB folders. Each folder will be replicated onto two disks for redundancy. I'm not zipping the folders because the files are in mostly compressed image formats already. I also don't want another layer of potential failure for if I went to unzip the folder 20 years the future. I am going to create a checksum of the root folder on each disk as well and store it on the disk as a text file. I believe SHA256 is a decent hash to use. I am still trying to decide between imgburn and Nero Burn and Archive which is included with my Verbatim drive writer. Any thoughts? My main priority is the ability to access the data easily in the future regardless of what formats are supported then.
