 Hi guys welcome back to my youtube channel this is Daniel Rosel here. I made a video before about burning M-discs on Windows and I ended up on Ubuntu sorry I ended up having to use VMware and you know virtual machine and it didn't work just fine I was actually not expecting that but then I saw on reddit people were saying yeah there's no problem getting the M-disc to burn using k3b so I knew there was something fishy and I went thinking about it and then I eventually figured it out what the problem was in my case I was connecting my M-disc burner, Blu-ray M-disc burner through USB hub and that was causing great issues with the USB rider being detected so I said why don't I try just connecting it directly to the computer and tape resto so here is so that's what I've just gone ahead and done so what I'm actually doing here is I'm going to be I'm really doing a duplication process here I've burned my the last three years my video production efforts on to an M-disc library using the previous method I described in VMware but of course I'd rather work directly in Linux what I'm doing now is I'm actually M-disc by M-disc I'm creating duplicates so that I can create an offsite backup archive so what you're seeing here and the program looks to be kind of just a little bit frozen for a tiny bit of time here what you're seeing is a folder with the contents of the previous M-disc so I'm just going to grab them all and I'm going to just chuck them over to the new M-disc and this is an M-disc it's a 25 gig capacity you get 23.3 of usable capacity so I'm filling up my archives to about the 20 I'm trying to get as close to 23 as possible but this one I left a little bit more but you can do more sophisticated stuff like leaving parity data I'm at the kind of elementary stage of this if you want to do this properly name your project etc etc but I'm going to go for the quick and dirty method I'm going to click on burn and you do get some options here you get for instance that the writing mode the the time can be up to four times and you've actually got an option to create multiple copies which would be super useful if you're doing this this sorry directly remember I just did a video about offsite approaches and you want to create three two one compliant backups always so you want to always burn each data each data pool twice one for your onsite one for your offsite so to make this process a bit less tedious you could do two copies and run them one after the other so I've dumped in my data I'm not doing anything fancy here I get I'm using auto speed mode I do get two times and four times these are four times four times disks but I'm going to just let the computer do it and I'm not going to verify the data this is again a kind of more quick and dirty if you will and then I'm going to click on burn basically so we are firing up in k3b onto an m disk it's enabled the udf extension now I'm not going to I'm going to click exit when we actually start the burning process because no one wants to sit through a 30 minute burn that's about how long it takes me to write 20 gigs onto each m disk I'm just going to get as far as to validate that it's that it's working I'm just paying attention at this moment to the various things here for instance this is the product name you can see wp-50 nb-40 it's from um LG company that's my burner so I know hey good we're using the right optical thing and once I see this I know we're in something's happening right so I'm watching so we've started the buffer the writing speed is uh is you can see 4496 kilobits per second one time so yeah this is going to be another slow burning process but um writing data is 71 85 of 1900 so we've just burned our first 100 megabytes of 19 uh 0.5 and everything looks like it's uh going ahead to me so this is uh k3b the burning process of an m disk I'm waiting for that first uh one percent to talk up to the clock up I guess it's going to be when I get to 192 there we go one percent estimated remaining time two hours this is dreadfully slow I think I was getting four times um write speed on the um using I'm using burnware on windows so the next disk because I have 16 of these delights to uh copy over to my offsite I'm going to play around and try manually crank that burn speed up to four because writing m disks writing 20 gigabytes at one time is burn speed as you can see is a rather painful process uh so this is it anyway here's k3b in action working away on burning a m disk m disk of course being a modified version of the blu-ray dvd for long term archival cold storage and a super cool project really interesting way in my opinion of doing backup instead of trusting your data to random cloud providers uh get yourself a code on a copy or you could just do you could also do backup onto your nes and then duplicate the nes onto m disk 20 25 50 or 100 gigs at a time and then set up your own offsite archive in somewhere like your um your your office or your friend's house or some uh you know um equivalent iron mountain that isn't a commercial service anyway this is k3b in action on an m disk hope this video was useful and feel free to subscribe to get more videos from this youtube channel thank you guys for
