I use the following command to do the backup:
tar -cSpvf - -V "Full Root Backup $datum" \
/System.* /bin /boot /dev /etc /home /lib /opt \
/root /sbin /usr /var /vmlinuz /vmlinuz.old \
2> /tmp/FullRootBackup.${datum} | \
gzip -q5 | \
buffer -o /dev/ntape -m 2048k -p 50
and the tape stops once a minute, but i think for changing the tape
direction. It does not this run-stop-rewind-run-stop-rewind-shit....
Another question (i asked earlier but no answers...)
I need a running bootdisk with ftape 4.02, the one i created does not work
cause of errors during reading the tape. Someone who has a good and
running boot/root disk set and who send me disk-images ?!?
Thanks,
Alexander.
