postgresql备份的sh

 

 

#!/bin/sh
# Get FileName from 'Date' command
DATAFILE=`date '+testdb2009_back%y%m%d.gz'`
DATADIR=/usr/local/pgsql/backup_testdb2009

echo "Backup is beginning."
/usr/local/pgsql/bin/pg_dump testdb2009 | /bin/gzip > "$DATADIR/$DATAFILE"
echo "Backup is done."

 

 

 

稍微修改下

   su -l postgres -c "/usr/local/pgsql/bin/pg_dump testdb2009 | /bin/gzip > '$DATADIR/$DATAFILE'　"
放到/etc/cron.daily下面每天备份

要是有问题，一般是权限问题
