You can use tar command as usaul for making up backup. Generally tape device name is st0 under OpenBSD.
To find out tape device use dmesg command: Code:
dmesg Code:
dump -0au -f /dev/nrst0 /dev/rsd0h a = determine tape media length u - Update the file /etc/dumpdates to record when backup was last created -f /dev/nrst0 = tape name /dev/rsd0h = partition name (use mount command to see all partition names) Rewind tape Code:
mt -f /dev/rst0 rewind Code:
restore -tvs 1 -f /dev/rst0 To restore use commad (let us say /home again) Code:
cd /home restore -rs 1 -f /dev/rst0
