How Do I Backup My PostgreSQL Database with Cron?

Question

I can run commands like vacuumdb, pg_dump, and psql just fine in a script if I preface them like so:

/usr/bin/sudo -u postgres /usr/bin/pg_dump -Fc mydatabase &g         


        

Answer 1

I have set my cron like this. Every 59 minutes since monday to friday

*/59 * * * 1-5 sh /home/my_user/scripts/back_my_bd.sh 

The script to run the backup is inside back_my_bd.sh file and the content is:

pg_dump -U USERDATABASE DATABASENAME > /home/my_user/sql/mybackup.sql

And i created the .pgpass file inside home directory to allow the backup whithout specify the user and password

localhost:5432:DATABASENAME:USER:PASSWORD

Sorry my english is not good!
