Обсуждение: Re(2): Crontab and PostgreSQL Backup

you can also try this:

#!/bin/sh

# Backing up each database...
pg_dumpall -o | bzip2 > /var/lib/pgsql/backups/pgdumpall_`date
"+%Y%m%d"`.bz2

# Removing backups of last seven days...
find /var/lib/pgsql/backups -mtime +7 -exec rm -f {} \;

or:

#!/bin/bash
PREFIX=/directory
DATABASE=db
rm -f $PREFIX.last
pg_dump -d $DATABASE -f $PREFIX.last
ln -f $PREFIX.last $PREFIX.hour.`date +%H`
ln -f $PREFIX.last $PREFIX.day.`date +%d`
ln -f $PREFIX.last $PREFIX.month.`date +%Y%m`

Run this every hour, and $PREFIX will contain backups for every hour for
the last day, every day for the last month and one backup for every
month.

here's a backup script we use

#!/bin/sh
cd /pgsql/backups
if [ ! -d $1 ]
then
        mkdir $1
fi
cd $1
for i in `ls $2 | egrep -v "template1|udmsearch"`
do
        /usr/local/bin/rotate_files.pl $i 7
        /pgsql/bin/pg_dump -p $1 -h localhost $i > $i.0
        gzip -f $i.0 &
done
