My photos rest on my 8tb WD Pro NAS drive, and OMV does a backup on another smaller 2TB drive. I also have an external 2TB for occasional extra backups. I plan on converting all my dvdr and cdrs into hdd data. Sadly, a bunch of my cdrs are kaput, rotted and falling apart. I never realized how important it was to buy burnable media that uses chemicals instead of organic dyes. I guess I just assumed 15yrs ago it was all chemical.
