This is how I always backed up my digital photos: burn them on one brand of DVD-R(Verbatim, for example), then burn again on a different brand of DVD-R(Sony or TDK), then copy all of them to a WD external hard drive. I keep them in separate places. On top of that, I also back them up on a cloud server. Yes, I know that sounds very paranoid, but as the "official" keeper of family photos, I have photos dating all the way back to 1940. It took me two and half years to scan carefully, one at a time. I could have sent them out and had them done commercially, but I seriously had doubt that they would look at EACH photo carefully before scanning them. At last count, there are almost 50,000 photos.
Now that I have a new BD-R burner, I figured I might as well make another copy on BD-R. My first batch consists of 11,000 digital photos. It sure took a long time to burn them, as there are 11,000 files. I'm wondering if I should place them in a zipped or RAR file so they burn as one single file? Which is better for data integrity in the long run?
Thanks!
