Re: database backup

Oh heck yeah. So here's a script for you (I wrote it mostly in the mail
client so you have to do your own testing). Now schedule that in cron via
a line like:

@daily /....command

#!/bin/sh
rm -rf /tmp/pg_data.*
TMPDIR=`mktemp -d /tmp/pg_data.XXX`
SENDTO=somone(at)somewhere

# Create the temporary directory
mkdir $TMPDIR/postgres

# dump each database schema/data separately
su -l postgresql -c "psql -At -F ' ' -U postgresql -d template1 <<__END__
SELECT datname FROM pg_database WHERE datallowconn;
__END__
" | while read DB; do
echo "PostgreSQL db $DB"
mkdir -p $TMPDIR/postgres/$DB

# schema
su -l postgresql -c "pg_dump -Cs -F c -Z 9 -S postgresql $DB" \
> $TMPDIR/postgres/$DB/schema.pg

# data
su -l postgresql -c "pg_dump -bd -F c -Z 9 -S postgresql $DB" \
> $TMPDIR/postgres/$DB/data.pg
done
# dump all globals (users/groups)
su -l postgresql -c "pg_dumpall -g" \
> $TMPDIR/postgres/globals.sql

# Create a archive, bzip it an mail it
tar cf - $TMPDIR/postgres | \
bzip -9 | \
perl -Mstrict -Mwarnings -MMIME::Base64 -e \
'my $buf;binmode STDIN;while(read(STDIN, $buf, 60*57)) {print
encode_base64($buf)}' | \
mail -s "Pg backup $SENDTO
