tar, backup, growisofs, file names
i want to backup my workstation (and soon my firewall remotely)
to the dvd+rw media i bought especially for that reason.
right now i use tar (for simplicity and long-term compatibility)
and growisofs like this:
/bin/tar cf - --files-from $INCLUDEFILE \
--exclude-from $EXCLUDEFILE \
--absolute-names \
| bzip2 --best --stdout \
| growisofs -Z /dev/dvd=/dev/fd/0
like this, growisofs writes to the raw medium, without a fs (i
think). that is half ok for full backups, but i wanted to do
incremental backups, too, to the same dvd.
how can i have * reading from stdin (from tar/bzip)
* named backup files and a filesystem
* no writing to hardisc first (i dont want
to rely on 4.4G beeing free.)
can i somehow give names to files which are created be reading
from stdin?
will i have a filesystem then, so i can mount the dvd and access
singel files?
