the sysad on my end, does something like this (backs up the entire
directory) as a weekly cronjob:
/etc/init.d/postgresql stop > /dev/null
rsync -a -H --delete /var/lib/pgsql/ /scratch/pgsql
/etc/init.d/postgresql start > /dev/null
then /scratch/pgsql is backed up over to two different machines. the
DB that i run does not need to be live 24/7, so this stopping and
starting works with us. how safe is this method? in other words, when
things get screwed, will a rsync from /scratch/pgsql to /var/lib/pgsql
save a life? i know it DIDNOT when the server was upgraded from 32-bit
to 64-bit and i was forced to recreate the whole DB!!
