Mine is neatly and reproducibly ill.
LOL
What is not ill on my system is xorriso.
Did you try it meanwhile ?
No I didn't as of then. My bad. I just wanted to try a couple more
things in cdrskin first, amonst the "other" IT work I'm doing :P
So, I diffidently need to try it before I responed back. WOW. Looking
at your man page, this is come impressive stuff! (After my experience
with all the other stuff) I have to say, I tried breaking it and for the
most part...getting the data saved, that worked!
Both problem reports seem to be related with
block device buffered i/o after expanding the
content of the media.
xorriso does not do such i/o.
Yeap, it still doesn't quite work there. I would mount the drive, even
after using a -commit switch and it still wouldn't work until I did an
eject-reinject. But I did do a continous three session burn without
ejecting, and it still retained all the previous files :)
A test run for only checking readability of
the directory tree would be:
$ xorriso -indev /dev/sr0 -dus '/*'
xorriso 0.1.0 : RockRidge filesystem manipulator, libburnia project.
...
xorriso : UPDATE : 41941 nodes read in 13 seconds
Drive current: -indev '/dev/sr0'
Media current: DVD+RW
Media status : is written , is appendable
Media summary: 1 session, 720130 data blocks, 1407m

Here's my newly, modified script:
------------------------------
#!/bin/bash -x
echo "Initializing Burn.Zimbra"
discDrive=/dev/scd0
backupLoc=/media/sdc1/raws/backups/zimbra
isoLoc=/zimbra
volID='Zimbra_Backup'
echo "Burning Disc"
xorriso -volid $volID -dev $discDrive -pathspecs on -overwrite off
-joliet on -add $isoLoc=$backupLoc -commit
echo "Backup Complete"
----------------------------------------------
I'm not sure if I really need the -commit since I'm only using one
drive. I'm assuming an -eject would fix my "readablity" problem, but I
haven't tried it yet. But I did as before, put the new file in
directory, move the old file out of directory, burn. Repeat. This works.
Tomarrow, I try doing a lot with and without ejecting the disc to test.
