I am in need of backuping quite a volume of data, so DVD's would feel like old time floppy backup. I was thinking of turning to blu-ray (M-Disc as they advertise long life).
Does anyone know if TDE's k3b can write on Blu-ray, or would I have to install KDE's (or rather some Gnome stuff?). Debian Buster here.

Hi Thierry, we did some work recently on TDE to add some support for bluray discs, but I have no clue if it works in k3b. If you are on PSB or PTB you could give it a try and let us know.
Personally, if I need to back up lot of data (perhaps frequently) I would buy a cheap harddisk and use that as backup. IF you need extra protection you can have more than one HD and either have multiple backups or use RAID config.

I will do, as I'd rather not pull KDE in. There seems to be an appimage of k3b however, which could be a solution if TDE's k3b does not do the job.

M Discs pretend to be secure for 1000 years (!) although I guess that in 30 years or so I won't bother anymore :)
I do have hard disc backups but hard discs do die...

I can appreciate your not wanting to mess up your TDE system with krap from KDE4/5 or Plasma, and other desktops have their problems, too. So I would install a non-TDE version of K3b only as a last resort.
It may be that you only need the blu-ray libraries. I would be glad to test this for you, but I have no blu-ray discs, and besides I have just blown my wad on buying a small collection of hard drives for extra storage and backup.
When I run "sudo apt-cache search blu-ray", the Devuan/Debian repositories only return a few items:
libbluray-bin libbluray1-dbg aacskeys dumphd libbluray-bdj libbluray-dev libbluray-doc libbluray1
also tsmuxer tsmuxergui (And I believe these last couple are just for burning films to DVD, rather than data.)
Otherwise, you might consider trying command-line, as there is no need to install anything that is non-TDE, and you are basically performing the same tasks, only without the GUI.
https://www.linuxquestions.org/questions/slackware-14/k3b-and-bluray-burning... https://wiki.debian.org/BurnCd https://www.linuxsecrets.com/2964-burning-cd-dvd-drives https://help.ubuntu.com/community/CdDvd/Burning
A couple of those links are pretty detailed, and if it is possible, they lay it out for you step-by-step.
Good luck!

Well, it does not work. k3b does "see" the blu-ray disc and it's capacity, but it obviously doesn't know that more than a DVD DL can be burned (I tried with TDE 4.0.9).
I found out that xfburn (leftover from my initial xfce install) does work (although it also does not offer "Blu-Ray". So I'd say the limitation is in k3b's code (k3b actually let's me add data, but it does not accept the Blu-Ray disc as a possible target).

Unless the Trinity people have added it in KDE/K3B did not have the ability to write Blu-rays until they moved to the 4 code base. You will have to use a different piece of software or command line unfortunately.

ah ah, thanks for checking on this :-) aat least now we know that.
Harddisks do fail from time to time, that is why I suggested you could use more than one. The likelihood of 2 or more HD failing at the same time + your main HD to fail at the same time as well is super low. CD/DVD/BD disks could potentially fail too, get scratched, broken.....

Definitly. But CD/DVD/BD use less space, you can burn 10 of them if necessary :)

I can second that. It seems it depends on the materials use for producing them. Last year I checked many backup cds from the past before throwing away. Some written in 2002 were working and most written in 2007 were failing. The hard drives written back then still work. And today we have also SSDs - I don't know how long they can reliably store information without being powered. Does someone has reference?

Don't go for a promotion and buy several from the same production lot. Did that one time and the three discs died the same week... So super low but possible.

The fist recordable CDs were *a lot* more expensive then. I guess you get what you pay for.
The hard drives written back then still work.
I got some Samsungs that would never power on after a few years on the shelf.
So, for very important data, I backup on everything :) When you loose data and have no backup you can curse your own stupidity. But when you know you are secure because you have a backup and then your backup is unreadable...

thats why I moved on to backup server 5.5TB with borg build on tiny core2 board. Every other way is too time consuming and/or expensive. With deduplication and 6months retention it has 1.2TB Now considering 3-4TB SSD to make backup of the backup :)

Speaking of backup strategies, I keep backup on two external drives (both are intended to be mirrors of each other in case one fails) and sychnronise everything using a tool known as unison. Unison also supports remote backups, so that you can use it with a remote server via ssh.

Heresay with no proof, but, I've heard SSD's:
- data is good for about 6 months without power. - data is dead after about 1 year without power.
Read it on the internets...

I always write CDs/DVDs at 1/2 or a little more of the maximum speed of the drive or the disk, whichever is lower. It seems to get a better write than using the max speed, because I never have write failures, and I have disks that are almost 20 years old and still readable.

Sometimes you can get an old drive to spin up by giving it a quick twist around the axis. The idea is to make the platters move a little; then sometimes it'll start.

apart from the blu-ray question regarding k3b
why don't you use external hard drive? IMO optical media for backup is not reliable Also I can recommend borg as it deduplicates, so you'll save a lot of space.
if I were you, I would go this way.

caveat: retired no longer have my workstation:
It has been a few years, I used to back-up my business home directory with Bluray. at the time none of the gui apps in any of the DE's supported bluray, if I am rembering correctly.
I was using the 25GB disks , there is more capacity now. Afaik, you can get "archival" quality BD disks. I created a "file" of my home dir, then burned it to BD, Easy to store.
Some notes left over :
truncate --size=25GB /pub/bluray.udf mkudffs /pub/bluray.udf sudo mount -oloop,rw /pub/mybr.udf /mnt/bluray sudo chown pabi.pabi /mnt/bluray
#growisofs -speed=6 -Z /dev/dvd=/pub/bluray.udf
