[KLUG Members] xfsdump

i.e.:

TODAY="$(date +%Y%m%d)"
xfsdump -e -o -l 0 -F -L "root-${TODAY}"  -f /dev/st0 /
xfsdump -e    -l 0 -F -L "srv-${TODAY}" -f /dev/nst0 /srv
xfsdump -e    -l 0 -F -L "home-${TODAY}" -f /dev/nst0 /home
xfsdump -e    -l 0 -F -L "boot-${TODAY}" -f /dev/nst0 /boot
xfsdump -e    -l 0 -F -L "opt-${TODAY}" -f /dev/nst0 /opt
xfsdump -e    -l 0 -F -L "var-${TODAY}" -f /dev/nst0 /var
