>Description:
Well, I missed a way to let the System do snapshots
in an automated way.
I try to add snapshots to /etc/periodic/daily/311.snapshots.
(I have no clue if one needs to order a number)
At current state I ask if it is a good a Idea to build
*daily* snapshots of a partition. According to some backup
strategies, I would say no.
(Well, some time ago, I submitted some simpler stuff for
security reasons, and It looks like no-one cares. :/
http://www.freebsd.org/cgi/query-pr.cgi?pr=82823
I conformed myself with the Idea that this patch simply
did not fit into the philosophy of freebsd. Maybe it is
a kind of freedom not to configure the Base System.)
>How-To-Repeat:
man mksnap_ffs
/.snap
/usr/.snap
/home/.snap
Watch empty .snap directories.
Watching at the .plan9 machine :)
>Fix:
First raw stuff that works for me:
case "$daily_snapshots_enable" in
[Yy][Ee][Ss])
echo ""
echo "Doing daily snapshot:"
enabled_snaps="/ /usr /home /nonexistant /var"
date="$(date +%Y-%m-%d.%H_%M)"
for s in $enabled_snaps; do
if ! test -d $s/.snap ; then
echo "failed chdir() to $s";
else
cd $s/.snap;
mksnap_ffs $s `basename $s`-$date; cd /;
fi;
done || rc=3
echo done. || rc=3
echo ""
echo "Listing current snapshots:"
snapinfo -a -v; ;;
*) rc=0;;
esac
exit $rc
