It's been about 2 years since I've backed up my e-books to optical disk.
Since then I have acquired a bit more and my e-library now sizes about
100 Gb.

Holey fucking moley!  If all those volumes were paper they would weigh
a thousand fucking tons -- and that's no exaggeration.

So I have to burn four 25 Gb bdr (that's Blu-Ray) disks.

Here is the GNU/Linux command:

growisofs -dvd-compat -speed=2 -udf -iso-level 3 -Z /dev/sr0 -J -r -graft-points /<cd drive dir>/=/<local dir>/ ...

This will produce a hybrid UDF/ISO-9660 filesystem because ISO-9660
by itself does not support files larger than 4.38 Gb.

It will also allow direct copying of files without having to create
an intermediate UDF/ISO-9660 file mounted as loop back.

The "-J" option is a kludge to allow "Joliet extensions" which may
allow the disk to be read by the Microslop OS.  I say "may" because
Microslop has proven to be highly inferior when dealing with optical
media.  In the past I've had nothing but trouble, but the future promises
never to use Microslop again.  I shouldn't even use it but I need
to keep every avenue of recovery open -- even that garbage Microslop.

There is also a possible "-rock" option to create the Unix "Rock Ridge"
protocol, which is far, far, far superior in its capabilities than that
Microcrap Joliet.  However, because these files are just e-books in a
simple directory structure there is no need for it.

Now it's burn, baby, burn!

The "-speed=2" option will keep the burn speed at a minimum which
is much better for creating a faithful reproduction.  But the burn
time will be a few hours, even for 25 Gb.

I don't use higher capacity bdr, such as 100 Gb, because they may
be more error prone.

I also use M-Disc because it will outlive me (I am 24 years old):

Conclusion:

Unless you regularly burn your valuable data to optical media
then you are a fucking, losing, asshole idiot -- but we knew that
already.

Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha!

This is Nuxxie, out.
