From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You should be able to make a complete backup of a DVD to an iso file using dd.

But then would I be able to read them on any computer without burning them?
Yes. You could use vlc or even as an iso file just open them as a virtual drive.
I think VLC can also open them on Android.
yep, unfortunately it doesn't seem to be able to read from actual drives though.
That would get you an exact copy of the disk with everything on it. And also, while 200 DVDs sounded a lot, it's "only" 860GB (assuming 4,3GB/disk which I think is the most common for movies), so it's not stupidly expensive either. Obviously you'll want a RAID setup and most likely backups for that, so it's more than just a single 1TB drive, but still quite manageable.
Actually, 8.5GB. Movies are typically on dual layer discs.
They would probably compress pretty well, I imagine.
Majority of the data (video) is already compressed as MPEG-2 so I'd think it doesn't compress very well. But if you don't have enough storage it's always an option to re-encode video with something more modern and achieve smaller file sizes from that. But that also removes at least DVD menu and other 'format dependent' options.
Yeah, but I'm assuming there are many gains to be had if your compression method doesn't need to be stream decoded for real time playback.
I used K3b for that. It can copy to image and even ignore errors if necessary, though I didn't yet have to try that. It's 8.5GB per disc, so get some 2TB HDD for that.
