#886 — DVD-bak get2 DOS:8.3 FileNames?

While looking at my log of how to backup a partition to DVD,
I noticed that previous backups have got all file names in DOS:8.3
format.
That's no good, because multiple fileNames will translate to the
same DOS filename.

Here's the command line that I've got logged as what I used:--

-> use: 
mkisofs -R /mnt/p11  | cdrecord -v fs=6m speed=2 dev=2,0 -

What am I doing wrong?

== TIA

Not sure - I just tried 

mkisofs -R /etc/ > /tmp/iso.iso

mount -oloop /tmp/iso.iso /mnt
ls -l /mnt

and the result looks good.

bigger filenames are part of a DC/DVD extended format.

Frankly I have found DVDs crap for backup

What do you find bad about DVDs for backup?

For backups, I create a compressed tarball, split that up to DVD
size, and burn the DVDs.  For each DVD, I verify it on the drive
that burned it and then with a different drive.  Verification is
done by running 'diff' between the original tarball fragment and
the file from the mounted DVD.  Except for a drive going bad, it
is rare to see a coaster.

You need Rock Ridge Extensions, or Joliet Extensions, depending on 
whether you want to go Unixy or Windowsy. Or both?

Not enough switches?

I use :-

mkisofs \
-appid "Backup stuff" \
-publisher "Me" -preparer "Also Me" -sysid "LINUX" \
-volid "Volume name here" -gui \

-input-charset "iso8859-1" -iso-level 2 -joliet -joliet-long \
-rational-rock -full-iso9660-filenames \

-path-list "/tmp/listoffiles" \
-o "/tmp/theiso.iso"

Those two isolated lines of switches in the middle are my attempt to get 
compatibility with everything in sight. Seems to work for me.
