the problem is between drive and medium. growisofs tries to let the
drive reserve the predicted size of the emerging ISO 9660 filesystem.
The drive replies by SCSI error code 3,57,00 which is classified by
the specs as "Medium Error". But it may also be the drive's fault.
The message "FEATURE 21h is not on, engaging DAO" indicates that your
medium is DVD-R or DVD-RW, and that the drive does not offer the
opportunity to write it with write type "Incremental". So growisofs
chooses the other type "Disk-At-Once", which needs the RESERVE TRACK
command.
If the medium is a DVD-RW, then try whether it helps to format it.
Code:
dvd+rw-format -force /dev/sr0
Formatted DVD-RW get written without RESERVE TRACK command.
Given that there are obvious hardware problems, this might fail too.
If the medium is DVD-R or if DVD-RW formatting does not bring success,
consider to try your medium in a different DVD drive or to try different
media in the drive which you use now.
I expect best chances for success with DVD+RW media. They are quite
different from DVD-R and normally more reliable than DVD-RW.
DVD+R are treated different from DVD-R, too.
That's not the problem here. The missing "TABLE-OF-CONTENTS" is the
place where burners record the start addresses and sizes of the "tracks"
and their attributions to "sessions".
The failed growisofs command with option -Z expects to be applied to
a medium which is overwritable or blank. DVD-R cannot be overwritable
and cannot get blanked after having been written.
So this media type must be yet unused or it is not suitable for
growisofs -Z. I.e. zero tracks in zero sessions have to recorded in the
table-of-content.
> I now wonder what backup tool to use to create RO offsite, any ideas
What's "RO" in this context ?
Well, i do my backups locally to DVD and BD by my own programs scdbackup
and xorriso. So remote storage is out of my scope.
Note: compiling with Large File Support
compiling program temp_lock.c
temp_lock.c: In function ‘Get_username’:
temp_lock.c:47:15: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘__uid_t {aka unsigned int}’ [-Wformat=]
sprintf(name,"uid_%ld",geteuid()

Have a nice day

I tried to install your impressive software but sourceforge had 0.8 version.
I did find 0.9.2
./CONFIGURE_DVD
it reported similar errors
I will keep reading learning
thank you

Reason: structure
temp_lock.c:47:15: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘__uid_t {aka unsigned int}’ [-Wformat=]
sprintf(name,"uid_%ld",geteuid()
Hm. In my version i have a "(long int)" cast operator which prevents
this warning. It is quite a harmless problem, though.

This explains a lot.
Please post the complete compiler warnings and error messages (as attachment,
if large) or send them to scdbackup@gmx.net .

Whatever, scdbackup is specialized on using multiple media for one
backup. As substitute for dkopp you should first explore xorriso, which
is the backend for a single medium.
It is packaged as binary with most distros.
Have a look at https://www.gnu.org/software/xorriso/
and search for "The following command performs incremental backup.".
The example would have to be written as shell script and adjusted to the
names of your local files.
If you need a GUI, try xorriso-tcltk. (Packaged rarely by distros.
Just download https://dev.lovelyhq.com/libburnia/l.../xorriso-tcltk
put it into /usr/bin and give it x-permissions.)
Klick on the dark "Help" button to the upper right https://www.gnu.org/software/xorriso...ltk-screen.gif
nd read the description of
"- Burn a directory as only content onto a CD, DVD or BD"
"- Add more data to an appendable medium or to an ISO image data file"
