I am trying to add zisofs compression to an existing script that
uses xorriso to make a backup ISO image (NOT incremental) of
some files and directories. I have not been able to decipher the
documentation to figure out how to do this. Specifically, the
man page seems to say that that -exec is an xorriso option and
that
- -exec set_filter --zisofs --
can be used to set up a compression filter. But when I do that I
get the message
xorriso : FAILURE : Not a known command: '-exec'
Here's the present xorriso command. What I want is to compress
the files with zisofs so that the ISO image can be mounted and
files read transparently.
The OS is Debian Buster.
xorriso -outdev $BACKUPNAME/$FILENAME".iso" \
-volid $BACKUPNAME-$BACKUPDATE \
-not_paths /home/jack/Downloads /home/jack/Music -- \
-not_leaf '*.iso' \
-not_leaf '*.vdi' \
-not_leaf 'Downloads' \
-add /etc /var/www /home/jack*
Is there an example somewhere that shows how to do this?
Thanks!
