Backing up a FreeBSD system

[Martin Schweizer]

Hello Steve

I copied once a week my filesystems /, /usr and /var to a second hard drive 
with the following cron batch (it also mailed my the important files, fstab, 
dmesg.boot and disklabes):

#!/bin/sh
# Definition des Formates für das angehängte Datum
datum=`date "+%Y%m%d"`

# Sendet die Disklabels
/sbin/disklabel ad0 | /usr/bin/mail -s ad0_disklabel your at isp.com
/sbin/disklabel ad2 | /usr/bin/mail -s ad2_disklabel your at isp.com
# Sendet fstab
/usr/bin/mail -s fstab your at isp.com < /etc/fstab
# Sendet dmesg.boot
/usr/bin/mail -s dmesg.boot your at isp.com< /var/run/dmesg.boot

# Löschen der bestehenden Dateien
/bin/rm /disk2/backup/*.dmp

# Dump wird erstellt. Wenn nicht erfolgreich (-> exit codes), 
# wird ein Mail an your at isp.com versendet
/sbin/dump -0au -f /disk2/backup/usr_$datum.dmp /usr || /usr/bin/mail -s Backup-Fehler your at isp.com
/sbin/dump -0au -f /disk2/backup/var_$datum.dmp /var || /usr/bin/mail -s Backup-Fehler your at isp.com
/sbin/dump -0au -f /disk2/backup/root_$datum.dmp / || /usr/bin/mail -s Backup-Fehler your at isp.com

# Exitcode
exit 0

Hope, this helps.
