(There are more in /var/cron/crontabs) Also, I suggest for completeness that you always specify the "-f" flag to tar, so that the device is clear to someone reading the file. Trusting the defaults, which might change one day, is nerve wracking. Also, consider that the restore may be done in a stressful situation. The default (on my system) is /dev/rsa0 which rewinds after close. I also suggest that you always make tapes with relative paths (even though our version of tar can treat absolute paths as relative). Add "-C / ." to the flags. > The mail generated by the backup appeared good (although I am uncertain > whether /root or the others were in the list). Too bad you didn't save this. Perhaps change the crontab entry to dump this to a file. > tar -tvz displays entries from: /dev, /stand, /etc. It does not show > those mentioned above.

Do you get different results without the -z switches? The first thing I suggest is making another tape (via the same procedure, or by hand) and saving the output. Then saving the "-xvf" output. At that point we can look to see what definately did or did not show up on the tape.
