    DVD Backup - technique, not licencing/copyright

    I have a collection of school made DVD films, some of which are quite valuable as teaching resources (especially film of dodgy experiments with mercury etc) that I want to back up. This is in addition to making them available on ClickView, but we need to avoid compression losses.

    What I'd like to have some view on, is how to do it. I'm thinking of copying them to an external HDD, and then storing that somewhere safe. What is the best way to create an image on a HDD that can simply be copied onto a new DVD in the event of loss or damage.

    Is it best to simply copy the Video TS folder across? Or is there a better way to create a burnable image?

    I would make .iso s out of them, that way you can burn them quickly and play them if you have something like daemon tools or vlc.

    ImgBurn will create ISO files, and I think it might also have its own error-checked image format. All ISO files are are simply copies of an entire CD or DVD, so on Linux you can simply use dd:

    dd if=/dev/cdrom of=myImage.iso

    If you wanted something automated you could maybe make a script that did the above dd command everytime a new DVD was placed in the drive.

    I'd also convert them to ISO with DVD Decrypter. You could save a bit of space by converting them to AVI.

    I'd go for ISOs but also make master dvd backups because if a teacher needs it for the next lesson and they're being monitored and the world will end if..., you probably won't have time to burn a new dvd.

    Their problem, not mine! But thanks for the iso thoughts, I'll experiment.
