FWIW, a USB DVD or Blu-Ray drive can be had for a very reasonable price, and MakeMKV is pretty straightforward and works pretty much perfectly on the big three OS's (Windows, Mac, Linux). If you're afraid of the DVDs breaking, it's not necessarily a bad idea to just keeping a digital backup somewhere.

Of course, if you're not careful you end up like me having spent multiple thousands on disks and servers and data tape backups, so be less dumb than me.
